ARM: 7599/1: head: Remove boot-time HYP mode check for v5 and below
The kernel can only be entered on HYP mode on CPUs which actually
support it, i.e. >= ARMv7. pre-v6 platform support cannot coexist
in the same kernel as support for v7 and higher, so there is no
advantage in having the HYP mode check on pre-v6 hardware.
At least one pre-v6 board is known to fail when the HYP mode check
code is present, although the exact cause remains unknown and may
be unrelated. [1]
This patch restores the old behaviour for pre-v6 platforms, whereby
the CPSR is forced directly to SVC mode with IRQs and FIQs masked.
All kernels capable of booting on v7 hardware will retain the
check, so this should not impair functionality.

The SP804 driver statically initialises the cpumask of the clock event

constant NR_CPUS. This breaks SMP_ON_UP systems where the interrupt
controller handling the sp804 doesn't have the irq_set_affinity callback

Dave Jones reported a bug with futex_lock_pi() that his trinity test
exposed. Sometime between queue_me() and taking the q.lock_ptr, the
lock_ptr became NULL, resulting in a crash.
While futex_wake() is careful to not call wake_futex() on futex_q's with
a pi_state or an rt_waiter (which are either waiting for a
futex_unlock_pi() or a PI futex_requeue()), futex_wake_op() and
futex_requeue() do not perform the same test.
Update futex_wake_op() and futex_requeue() to test for q.pi_state and
q.rt_waiter and abort with -EINVAL if detected. To ensure any future
breakage is caught, add a WARN() to wake_futex() if the same condition
is true.
This fix has seen 3 hours of testing with "trinity -c futex" on an

writeback: put unused inodes to LRU after writeback completion
Commit
169ebd90131b ("writeback: Avoid iput() from flusher thread")
removed iget-iput pair from inode writeback. As a side effect, inodes
that are dirty during iput_final() call won't be ever added to inode LRU
(iput_final() doesn't add dirty inodes to LRU and later when the inode
is cleaned there's noone to add the inode there). Thus inodes are
effectively unreclaimable until someone looks them up again.
The practical effect of this bug is limited by the fact that inodes are
pinned by a dentry for long enough that the inode gets cleaned. But
still the bug can have nasty consequences leading up to OOM conditions
under certain circumstances. Following can easily reproduce the
problem:
for (( i = 0; i < 1000; i++ )); do
mkdir $i
for (( j = 0; j < 1000; j++ )); do
touch $i/$j
echo 2 > /proc/sys/vm/drop_caches
done
done
then one needs to run 'sync; ls -lR' to make inodes reclaimable again.
We fix the issue by inserting unused clean inodes into the LRU after
writeback finishes in inode_sync_complete().

mm: vmscan: check for fatal signals iff the process was throttled
Commit
5515061d22f0 ("mm: throttle direct reclaimers if PF_MEMALLOC
reserves are low and swap is backed by network storage") introduced a
check for fatal signals after a process gets throttled for network
storage. The intention was that if a process was throttled and got
killed that it should not trigger the OOM killer. As pointed out by
Minchan Kim and David Rientjes, this check is in the wrong place and too
broad. If a system is in am OOM situation and a process is exiting, it
can loop in __alloc_pages_slowpath() and calling direct reclaim in a
loop. As the fatal signal is pending it returns 1 as if it is making
forward progress and can effectively deadlock.
This patch moves the fatal_signal_pending() check after throttling to
throttle_direct_reclaim() where it belongs. If the process is killed
while throttled, it will return immediately without direct reclaim
except now it will have TIF_MEMDIE set and will use the PFMEMALLOC
reserves.
Minchan pointed out that it may be better to direct reclaim before
returning to avoid using the reserves because there may be pages that
can easily reclaim that would avoid using the reserves. However, we do
no such targetted reclaim and there is no guarantee that suitable pages
are available. As it is expected that this throttling happens when
swap-over-NFS is used there is a possibility that the process will
instead swap which may allocate network buffers from the PFMEMALLOC
reserves. Hence, in the swap-over-nfs case where a process can be
throtted and be killed it can use the reserves to exit or it can
potentially use reserves to swap a few pages and then exit. This patch
takes the option of using the reserves if necessary to allow the process
exit quickly.
If this patch passes review it should be considered a -stable candidate
for 3.6.

Hmm, so it's just took longer to hit the problem and observe
kswapd0 spinning on my CPU again - it's not as endless like before -
but still it easily eats minutes - it helps to turn off Firefox
or TB (memory hungry apps) so kswapd0 stops soon - and restart
those apps again. (And I still have like >1GB of cached memory)

prune_super+0x149/0x1b0
shrink_slab+0xba/0x510
The sysrq+m indicates the system has no swap so it'll never reclaim
anonymous pages as part of reclaim/compaction. That is one part of the
problem but not the root cause as file-backed pages could also be
reclaimed.
The likely underlying problem is that kswapd is woken up or kept awake
for each THP allocation request in the page allocator slow path.
If compaction fails for the requesting process then compaction will be
deferred for a time and direct reclaim is avoided. However, if there
are a storm of THP requests that are simply rejected, it will still be
the the case that kswapd is awake for a prolonged period of time as
pgdat->kswapd_max_order is updated each time. This is noticed by the
main kswapd() loop and it will not call kswapd_try_to_sleep(). Instead
it will loopp, shrinking a small number of pages and calling
shrink_slab() on each iteration.
The temptation is to supply a patch that checks if kswapd was woken for
THP and if so ignore pgdat->kswapd_max_order but it'll be a hack and not
backed up by proper testing. As 3.7 is very close to release and this
is not a bug we should release with, a safer path is to revert "mm:
remove __GFP_NO_KSWAPD" for now and revisit it with the view to ironing
out the balance_pgdat() logic in general.

of/address: sparc: Declare of_iomap as an extern function for sparc again
This bug-fix makes sure that of_iomap is defined extern for sparc so that the
sparc-specific implementation of_iomap is once again used when including
include/linux/of_address.h in a sparc context. OF_GPIO that is now available for
sparc relies on this.
The bug was inadvertently introduced in a850a75, "of/address: add empty static
inlines for !CONFIG_OF", that added a static dummy inline for of_iomap when
!CONFIG_OF_ADDRESS. However, CONFIG_OF_ADDRESS is never defined for sparc, but
there is a sparc-specific implementation /arch/sparc/kernel/of_device_common.c.
This fix takes the same approach as 0bce04b that solved the equivalent problem
for of_address_to_resource.

we forgot to drop buffer lock before waiting for transaction commit and thus
deadlock is possible when kjournald wants to lock the buffer.

Instead, check beforehand and stash the result in a temporary.

ARM: 7583/1: decompressor: Enable unaligned memory access for v6 and above
Modern GCC can generate code which makes use of the CPU's native
unaligned memory access capabilities. This is useful for the C
decompressor implementations used for unpacking compressed kernels.
This patch disables alignment faults and enables the v6 unaligned
access model on CPUs which support these features (i.e., v6 and
later), allowing full unaligned access support for C code in the
decompressor.
The decompressor C code must not be built to assume that unaligned
access works if support for v5 or older platforms is included in
the kernel.
For correct code generation, C decompressor code must always use
the get_unaligned and put_unaligned accessors when dealing with
unaligned pointers, regardless of this patch.

ipv4: do not cache looped multicasts
Starting from 3.6 we cache output routes for
multicasts only when using route to 224/4. For local receivers
we can set RTCF_LOCAL flag depending on the membership but
in such case we use maddr and saddr which are not caching
keys as before. Additionally, we can not use same place to
cache routes that differ in RTCF_LOCAL flag value.
Fix it by caching only RTCF_MULTICAST entries
without RTCF_LOCAL (send-only, no loopback). As a side effect,
we avoid unneeded lookup for fnhe when not caching because
multicasts are not redirected and they do not learn PMTU.
Thanks to Maxime Bizon for showing the caching
problems in __mkroute_output for 3.6 kernels: different
RTCF_LOCAL flag in cache can lead to wrong ip_mc_output or
ip_output call and the visible problem is that traffic can
not reach local receivers via loopback.

mt9v022_s_crop(). In manual mode this register should be set to the

outside of the actual control function means that the register value

md/raid10: close race that lose writes lost when replacement completes.
When a replacement operation completes there is a small window
when the original device is marked 'faulty' and the replacement
still looks like a replacement. The faulty should be removed and
the replacement moved in place very quickly, bit it isn't instant.
So the code write out to the array must handle the possibility that
the only working device for some slot in the replacement - but it
doesn't. If the primary device is faulty it just gives up. This
can lead to corruption.
So make the code more robust: if either the primary or the
replacement is present and working, write to them. Only when
neither are present do we give up.

netfilter: ipset: Fix range bug in hash:ip,port,net
Due to the missing ininitalization at adding/deleting entries, when
a plain_ip,port,net element was the object, multiple elements were
added/deleted instead. The bug came from the missing dangling
default initialization.
The error-prone default initialization is corrected in all hash:* types.

fix incorrect NR_FREE_PAGES accounting (appears like memory leak)
There have been some 3.7-rc reports of vm issues, including some kswapd
bugs and, more importantly, some memory "leaks":
http://www.spinics.net/lists/linux-mm/msg46187.html
https://bugzilla.kernel.org/show_bug.cgi?id=50181
Commit
1fb3f8ca0e92 ("mm: compaction: capture a suitable high-order page
immediately when it is made available") took split_free_page() and
reused it for the compaction code. It does something curious with
capture_free_page() (previously known as split_free_page()):
int capture_free_page(struct page *page, int alloc_order,
...
__mod_zone_page_state(zone, NR_FREE_PAGES, -(1UL << order));
- /* Split into individual pages */
- set_page_refcounted(page);
- split_page(page, order);
+ if (alloc_order != order)
+ expand(zone, page, alloc_order, order,
+ &zone->free_area[order], migratetype);
Note that expand() puts the pages _back_ in the allocator, but it does
not bump NR_FREE_PAGES. We "return" 'alloc_order' worth of pages, but
we accounted for removing 'order' in the __mod_zone_page_state() call.
For the old split_page()-style use (order==alloc_order) the bug will not
trigger. But, when called from the compaction code where we
occasionally get a larger page out of the buddy allocator than we need,
we will run in to this.
This patch simply changes the NR_FREE_PAGES manipulation to the correct
'alloc_order' instead of 'order'.
I've been able to repeatedly trigger this in my testing environment.
The amount "leaked" very closely tracks the imbalance I see in buddy
pages vs. NR_FREE_PAGES. I have confirmed that this patch fixes the
imbalance

md/raid5: Make sure we clear R5_Discard when discard is finished.
commit
9e44476851e91c86c98eb92b9bc27fb801f89072
MD: raid5 avoid unnecessary zero page for trim
change raid5 to clear R5_Discard when the complete request is
handled rather than when submitting the per-device discard request.
However it did not clear R5_Discard for the parity device.
This means that if the stripe_head was reused before it expired from
the cache, the setting would be wrong and a hang would result.
Also if the R5_Uptodate bit happens to be set, R5_Discard again
won't be cleared. But R5_Uptodate really should be clear at this point.
So make sure R5_Discard is cleared in all cases, and clear
R5_Uptodate when a 'discard' completes.

md/raid5: move resolving of reconstruct_state earlier in

The chunk of code in stripe_handle which responds to a
*_result value in reconstruct_state is really the completion
of some processing that happened outside of handle_stripe
(possibly asynchronously) and so should be one of the first
things done in handle_stripe().
After the next patch it will be important that it happens before
handle_stripe_clean_event(), as that will clear some dev->flags

ARM - OMAP: ads7846: fix pendown debounce setting
Commit
97ee9f01 (ARM: OMAP: fix the ads7846 init code) have enabled the
pendown GPIO debounce time setting by the below sequence:
gpio_request_one()
gpio_set_debounce()
gpio_free()
It also revealed a bug in the OMAP GPIO handling code which prevented
the GPIO debounce clock to be disabled and CORE transition to low power
states.
Commit c9c55d9 (gpio/omap: fix off-mode bug: clear debounce settings on
free/reset) fixes the OMAP GPIO handling code by making sure that the
GPIO debounce clock gets disabled if no GPIO is requested from current
bank.
While fixing the OMAP GPIO handling code (in the right way), the above
commit makes the gpio_request->set_debounce->free sequence invalid as
after freeing the GPIO, the debounce settings are lost.
Fix the debounce settings by moving the debounce initialization to the
actual GPIO requesting code - the ads7846 driver.

driver can not find any valid timing, the STDI block is restarted to measure
the video timings again. The function will return an error, but the restart of
STDI will generate a new STDI interrupt and the format detection process will
