ARM: OMAP: fix iommu, not mailbox
commit 134d12fae0bb8f3d60dc7440a9e1950bb5427167 upstream.
For some weird (freudian?) reason, commit 435792d "ARM: OMAP: make
iommu subsys_initcall to fix builtin omap3isp" unintentionally changed
the mailbox's initcall instead of the iommu's.
Fix that.

dm raid: set MD_CHANGE_DEVS when rebuilding
commit 3aa3b2b2b1edb813dc5342d0108befc39541542d upstream.
The 'rebuild' parameter is used to rebuild individual devices in an
array (e.g. resynchronize a RAID1 device or recalculate a parity device
in higher RAID). The MD_CHANGE_DEVS flag must be set when this
parameter is given in order to write out the superblocks and make the
change take immediate effect. The code that handles new devices in
super_load already sets MD_CHANGE_DEVS and 'FirstUse'. (The 'FirstUse'
flag was being set as a special case for rebuilds in
super_init_validation.)
Add a condition for rebuilds in super_load to take care of both flags
without the special case in 'super_init_validation'.

dm flakey: fix crash on read when corrupt_bio_byte not set
commit 1212268fd9816e3b8801e57b896fceaec71969ad upstream.
The following BUG is hit on the first read that is submitted to a dm

defer_bh() takes the lock which is hold during unlink_urbs(). The safe

carl9170: fix frame delivery if sta is in powersave mode
commit 9926a67557532acb6cddb1c1add02952175b5c72 upstream.
Nicolas Cavallari discovered that carl9170 has some
serious problems delivering data to sleeping stations.
It turns out that the driver was not honoring two
important flags (IEEE80211_TX_CTL_POLL_RESPONSE and
IEEE80211_TX_CTL_CLEAR_PS_FILT) which are set on
frames that should be sent although the receiving
station is still in powersave mode.

carl9170: Fix memory accounting when sta is in power-save mode.
commit 992d52529d7840236d3059b51c15d5eb9e81a869 upstream.
On Access Point mode, when transmitting a packet, if the destination
station is in powersave mode, we abort transmitting the packet to the
device queue, but we do not reclaim the allocated memory. Given enough
packets, we can go in a state where there is no packet on the device
queue, but we think the device has no memory left, so no packet gets
transmitted, connections breaks and the AP stops working.
This undo the allocation done in the TX path when the station is in
power-save mode.

hwmon: (zl6100) Maintain delay parameter in driver instance data
commit 7ad6307ad6968ce25cecf209d4822d4c722be030 upstream.
A global delay parameter has the side effect of being overwritten with 0 if a
single ZL2004 or ZL6105 is instantiated. If other chips supported by the same
driver are in the system, this will result in access errors for those chips.
To solve the problem, keep a per-instance copy of the delay parameter, and do
not change the original parameter.

Input: ALPS - fix touchpad detection when buttons are pressed
commit 99c90ab31fad855b9da9dee3a5aa6c27f263e9d6 upstream.
ALPS touchpad detection fails if some buttons of ALPS are pressed.
The reason is that the "E6" query response byte is different from
what is expected.
This was tested on a Toshiba Portege R500.

media: staging: lirc_serial: Fix init/exit order
commit 9105b8b200410383d0854bbe237ee385d7d33ba6 upstream.
Currently the module init function registers a platform_device and
only then allocates its IRQ and I/O region. This allows allocation to
race with the device's suspend() function. Instead, allocate
resources in the platform driver's probe() function and free them in
the remove() function.
The module exit function removes the platform device before the
character device that provides access to it. Change it to reverse the
order of initialisation.

xscale2 PMUs indicate overflow not via the PMU control register, but by

This patch fixes the xscale2 PMU code to use this register to detect

this could be false, so check that we do have a valid event before

commit 99c1745b9c76910e195889044f914b4898b7c9a5 upstream.
When disabling a counter on an ARMv7 PMU, we should also clear the
overflow flag in case an overflow occurred whilst stopping the counter.
This prevents a spurious overflow being picked up later and leading to
either false accounting or a NULL dereference.

ARM: 7354/1: perf: limit sample_period to half max_period in non-sampling mode
commit 5727347180ebc6b4a866fcbe00dcb39cc03acb37 upstream.
On ARM, the PMU does not stop counting after an overflow and therefore
IRQ latency affects the new counter value read by the kernel. This is
significant for non-sampling runs where it is possible for the new value
to overtake the previous one, causing the delta to be out by up to
max_period events.
Commit a737823d ("ARM: 6835/1: perf: ensure overflows aren't missed due
to IRQ latency") attempted to fix this problem by allowing interrupt
handlers to pass an overflow flag to the event update function, causing
the overflow calculation to assume that the counter passed through zero
when going from prev to new. Unfortunately, this doesn't work when
overflow occurs on the perf_task_tick path because we have the flag
cleared and end up computing a large negative delta.
This patch removes the overflow flag from armpmu_event_update and
instead limits the sample_period to half of the max_period for
non-sampling profiling runs.

OMAPDSS: HDMI: PHY burnout fix
commit c49d005b6cc8491fad5b24f82805be2d6bcbd3dd upstream.
A hardware bug in the OMAP4 HDMI PHY causes physical damage to the board
if the HDMI PHY is kept powered on when the cable is not connected.
This patch solves the problem by adding hot-plug-detection into the HDMI
IP driver. This is not a real HPD support in the sense that nobody else
than the IP driver gets to know about the HPD events, but is only meant
to fix the HW bug.
The strategy is simple: If the display device is turned off by the user,
the PHY power is set to OFF. When the display device is turned on by the
user, the PHY power is set either to LDOON or TXON, depending on whether
the HDMI cable is connected.
The reason to avoid PHY OFF when the display device is on, but the cable
is disconnected, is that when the PHY is turned OFF, the HDMI IP is not
"ticking" and thus the DISPC does not receive pixel clock from the HDMI
IP. This would, for example, prevent any VSYNCs from happening, and
would thus affect the users of omapdss. By using LDOON when the cable is
disconnected we'll avoid the HW bug, but keep the HDMI working as usual
from the user's point of view.

ARM: orion: Fix Orion5x GPIO regression from MPP cleanup
commit b06540371063f0f07aafc1d1ac5e974da85c973c upstream.
Patchset "ARM: orion: Refactor the MPP code common in the orion
platform" broke at least Orion5x based platforms. These platforms have
pins configured as GPIO when the selector is not 0x0. However the
common code assumes the selector is always 0x0 for a GPIO lines. It
then ignores the GPIO bits in the MPP definitions, resulting in that
Orion5x machines cannot correctly configure there GPIO lines.
The Fix removes the assumption that the selector is always 0x0.
In order that none GPIO configurations are correctly blocked,
Kirkwood and mv78xx0 MPP definitions are corrected to only set the
GPIO bits for GPIO configurations.
This third version, which does not contain any whitespace changes,
and is rebased on v3.3-rc2.

commit 5ed80a75b248bfaf840ea6b38f941edcf6ee7dc7 upstream.
According to i.MX27 Reference Manual (p 1593) TXBIT0 bit selects
whether the most significant or the less significant part of the
data word written to the FIFO is transmitted.
As DSP_A is the same as DSP_B with a data offset of 1 bit, it
doesn't make any sense to remove TXBIT0 bit here.

being in full power mode but the shutdown functionality assumes these
things. Add checks for the bias level at each stage so that we don't

commit 050f0e02c8dc38b2b4f2df345ac760d22ca5c7ba upstream.
VX900 can do hardware scaling for both IGAs in contrast to previous
hardware which could do it only for IGA2. This patch ensures that
we set the parameter for IGA2 and not for IGA1. This fixes hardware
scaling on VX900 until we have the infrastructure to support it for
both IGAs.

osd_uld: Bump MAX_OSD_DEVICES from 64 to 1,048,576
commit 41f8ad76362e7aefe3a03949c43e23102dae6e0b upstream.
It used to be that minors where 8 bit. But now they
are actually 20 bit. So the fix is simplicity itself.
I've tested with 300 devices and all user-mode utils
work just fine. I have also mechanically added 10,000
to the ida (so devices are /dev/osd10000, /dev/osd10001 ...)
and was able to mkfs an exofs filesystem and access osds
from user-mode.
All the open-osd user-mode code uses the same library
to access devices through their symbolic names in
/dev/osdX so I'd say it's pretty safe. (Well tested)
This patch is very important because some of the systems
that will be deploying the 3.2 pnfs-objects code are larger
than 64 OSDs and will stop to work properly when reaching
that number.

iwlwifi: fix key removal
commit 5dcbf480473f6c3f06ad2426b7517038a2a18911 upstream.
When trying to remove a key, we always send key
flags just setting the key type, not including
the multicast flag and the key ID. As a result,
whenever any key was removed, the unicast key 0
would be removed, causing a complete connection
loss after the second rekey (the first doesn't
cause a key removal). Fix the key removal code
to include the key ID and multicast flag, thus
removing the correct key.

mm: thp: fix BUG on mm->nr_ptes
commit 1c641e84719429bbfe62a95ed3545ee7fe24408f upstream.
Dave Jones reports a few Fedora users hitting the BUG_ON(mm->nr_ptes...)
in exit_mmap() recently.
Quoting Hugh's discovery and explanation of the SMP race condition:
"mm->nr_ptes had unusual locking: down_read mmap_sem plus
page_table_lock when incrementing, down_write mmap_sem (or mm_users
0) when decrementing; whereas THP is careful to increment and
decrement it under page_table_lock.
Now most of those paths in THP also hold mmap_sem for read or write
(with appropriate checks on mm_users), but two do not: when
split_huge_page() is called by hwpoison_user_mappings(), and when
called by add_to_swap().
It's conceivable that the latter case is responsible for the
exit_mmap() BUG_ON mm->nr_ptes that has been reported on Fedora."
The simplest way to fix it without having to alter the locking is to make
split_huge_page() a noop in nr_ptes terms, so by counting the preallocated
pagetables that exists for every mapped hugepage. It was an arbitrary
choice not to count them and either way is not wrong or right, because
they are not used but they're still allocated.

kprobes: return proper error code from register_kprobe()
commit f986a499ef6f317d906e6f6f281be966e1237a10 upstream.
register_kprobe() aborts if the address of the new request falls in a
prohibited area (such as ftrace pouch, __kprobes annotated functions,
non-kernel text addresses, jump label text). We however don't return the
right error on this abort, resulting in a silent failure - incorrect
adding/reporting of kprobes ('perf probe do_fork+18' or 'perf probe
mcount' for instance).
In V2 we are incorporating Masami Hiramatsu's feedback.
This patch fixes it by returning -EINVAL upon failure.
While we are here, rename the label used for exit to be more appropriate.

commit 8617b093d0031837a7be9b32bc674580cfb5f6b5 upstream.
rate control algorithms concludes the rate as invalid
with rate[i].idx < -1 , while they do also check for rate[i].count is
non-zero. it would be safer to zero initialize the 'count' field.
recently we had a ath9k rate control crash where the ath9k rate control
in ath_tx_status assumed to check only for rate[i].count being non-zero
in one instance and ended up in using invalid rate index for
'connection monitoring NULL func frames' which eventually lead to the crash.
thanks to Pavel Roskin for fixing it and finding the root cause.

cifs: fix dentry refcount leak when opening a FIFO on lookup
commit 5bccda0ebc7c0331b81ac47d39e4b920b198b2cd upstream.
The cifs code will attempt to open files on lookup under certain
circumstances. What happens though if we find that the file we opened
was actually a FIFO or other special file?
Currently, the open filehandle just ends up being leaked leading to
a dentry refcount mismatch and oops on umount. Fix this by having the
code close the filehandle on the server if it turns out not to be a
regular file. While we're at it, change this spaghetti if statement
into a switch too.

mm: memcg: Correct unregistring of events attached to the same eventfd
commit 371528caec553785c37f73fa3926ea0de84f986f upstream.
There is an issue when memcg unregisters events that were attached to
the same eventfd:
- On the first call mem_cgroup_usage_unregister_event() removes all
events attached to a given eventfd, and if there were no events left,
thresholds->primary would become NULL;
- Since there were several events registered, cgroups core will call
mem_cgroup_usage_unregister_event() again, but now kernel will oops,
as the function doesn't expect that threshold->primary may be NULL.
That's a good question whether mem_cgroup_usage_unregister_event()
should actually remove all events in one go, but nowadays it can't
do any better as cftype->unregister_event callback doesn't pass
any private event-associated cookie. So, let's fix the issue by
simply checking for threshold->primary.
FWIW, w/o the patch the following oops may be observed:

The problem lies with the allocation batching code. It will
opportunistically allocate kiocbs, and then trim back the list of iocbs
when there is not enough room in the completion ring to hold all of the
events.
In the case above, what happens is that the pruning back of events ends
up freeing up the last active request and the context is marked as dead,
so it is thus responsible for waking up waiters. Unfortunately, the
code does not check for this condition, so we end up with a hung task.

mmc: sdhci-esdhc-imx: fix for mmc cards on i.MX5
commit 5b6b0ad6e572b32a641116aaa5f897ffebe31e44 upstream.
On i.MX53 we have to write a special SDHCI_CMD_ABORTCMD to the
SDHCI_TRANSFER_MODE register during a MMC_STOP_TRANSMISSION
command. This works for SD cards. However, with MMC cards
the MMC_SET_BLOCK_COUNT command is used instead, but this
needs the same handling. Fix MMC cards by testing for the
MMC_SET_BLOCK_COUNT command aswell. Tested on a custom i.MX53
board with a Transcend MMC+ card and eMMC.
The kernel started used MMC_SET_BLOCK_COUNT in 3.0, so this
is a regression for these boards introduced in 3.0; it should
go to 3.0/3.1/3.2-stable.

Move Logitech Harmony 900 from cdc_ether to zaurus
commit ee932bf9acb2e2c6a309e808000f24856330e3f9 upstream.
In the current kernel implementation, the Logitech Harmony 900 remote
control is matched to the cdc_ether driver through the generic
USB_CDC_SUBCLASS_MDLM entry. However, this device appears to be of the
pseudo-MDLM (Belcarra) type, rather than the standard one. This patch
blacklists the Harmony 900 from the cdc_ether driver and whitelists it for
the pseudo-MDLM driver in zaurus.

genirq: Clear action->thread_mask if IRQ_ONESHOT is not set
commit 52abb700e16a9aa4cbc03f3d7f80206cbbc80680 upstream.
Xommit ac5637611(genirq: Unmask oneshot irqs when thread was not woken)
fails to unmask when a !IRQ_ONESHOT threaded handler is handled by
handle_level_irq.
This happens because thread_mask is or'ed unconditionally in
irq_wake_thread(), but for !IRQ_ONESHOT interrupts never cleared. So
the check for !desc->thread_active fails and keeps the interrupt
disabled.
Keep the thread_mask zero for !IRQ_ONESHOT interrupts.
Document the thread_mask magic while at it.

ALSA: hda - Add a fake mute feature
commit 3868137ea41866773e75d9ac4b9988dcc361ff1d upstream.
Some codecs don't supply the mute amp-capabilities although the lowest
volume gives the mute. It'd be handy if the parser provides the mute
mixers in such a case.
This patch adds an extension amp-cap bit (which is used only in the
driver) to represent the min volume = mute state. Also modified the
amp cache code to support the fake mute feature when this bit is set
but the real mute bit is unset.
In addition, conexant cx5051 parser uses this new feature to implement
the missing mute controls.

perf/x86/kvm: Fix Host-Only/Guest-Only counting with SVM disabled
commit 1018faa6cf23b256bf25919ef203cd7c129f06f2 upstream.
It turned out that a performance counter on AMD does not
count at all when the GO or HO bit is set in the control
register and SVM is disabled in EFER.
This patch works around this issue by masking out the HO bit
in the performance counter control register when SVM is not
enabled.
The GO bit is not touched because it is only set when the
user wants to count in guest-mode only. So when SVM is
disabled the counter should not run at all and the
not-counting is the intended behaviour.

S390: KEYS: Enable the compat keyctl wrapper on s390x
commit 1d057720609ed052a6371fe1d53300e5e6328e94 upstream.
Enable the compat keyctl wrapper on s390x so that 32-bit s390 userspace can
call the keyctl() syscall.
There's an s390x assembly wrapper that truncates all the register values to
32-bits and this then calls compat_sys_keyctl() - but the latter only exists if
CONFIG_KEYS_COMPAT is enabled, and the s390 Kconfig doesn't enable it.
Without this patch, 32-bit calls to the keyctl() syscall are given an ENOSYS
error:

commit aed3f09db39596e539f90b11a5016aea4d8442e1 upstream.
Before loading the lut (gamma), check the active state of intel_crtc,
otherwise at least on gen2 hang ensue.
This is reproducible in Xorg via:
xset dpms force off
then
xgamma -rgamma 2.0 # freeze.

compat: fix compile breakage on s390
commit 048cd4e51d24ebf7f3552226d03c769d6ad91658 upstream.
The new is_compat_task() define for the !COMPAT case in
include/linux/compat.h conflicts with a similar define in
arch/s390/include/asm/compat.h.
This is the minimal patch which fixes the build issues.

Fix autofs compile without CONFIG_COMPAT
commit 3c761ea05a8900a907f32b628611873f6bef24b2 upstream.
The autofs compat handling fix caused a compile failure when
CONFIG_COMPAT isn't defined.
Instead of adding random #ifdef'fery in autofs, let's just make the
compat helpers earlier to use: without CONFIG_COMPAT, is_compat_task()
just hardcodes to zero.
We could probably do something similar for a number of other cases where
we have #ifdef's in code, but this is the low-hanging fruit.

autofs: work around unhappy compat problem on x86-64
commit a32744d4abae24572eff7269bc17895c41bd0085 upstream.
When the autofs protocol version 5 packet type was added in commit
5c0a32fc2cd0 ("autofs4: add new packet type for v5 communications"), it
obvously tried quite hard to be word-size agnostic, and uses explicitly
sized fields that are all correctly aligned.
However, with the final "char name[NAME_MAX+1]" array at the end, the
actual size of the structure ends up being not very well defined:
because the struct isn't marked 'packed', doing a "sizeof()" on it will
align the size of the struct up to the biggest alignment of the members
it has.
And despite all the members being the same, the alignment of them is
different: a "__u64" has 4-byte alignment on x86-32, but native 8-byte
alignment on x86-64. And while 'NAME_MAX+1' ends up being a nice round
number (256), the name[] array starts out a 4-byte aligned.
End result: the "packed" size of the structure is 300 bytes: 4-byte, but
not 8-byte aligned.
As a result, despite all the fields being in the same place on all
architectures, sizeof() will round up that size to 304 bytes on
architectures that have 8-byte alignment for u64.
Note that this is *not* a problem for 32-bit compat mode on POWER, since
there __u64 is 8-byte aligned even in 32-bit mode. But on x86, 32-bit
and 64-bit alignment is different for 64-bit entities, and as a result
the structure that has exactly the same layout has different sizes.
So on x86-64, but no other architecture, we will just subtract 4 from
the size of the structure when running in a compat task. That way we
will write the properly sized packet that user mode expects.
Not pretty. Sadly, this very subtle, and unnecessary, size difference
has been encoded in user space that wants to read packets of *exactly*
the right size, and will refuse to touch anything else.

ARM: OMAP: make iommu subsys_initcall to fix builtin omap3isp
commit 435792d93410f008120c4dbab148019a3cc31dbc upstream.
omap3isp depends on omap's iommu and will fail to probe if
initialized before it (which always happen if they are builtin).
Make omap's iommu subsys_initcall as an interim solution until
the probe deferral mechanism is merged.
