Ben Tebulin reported:
"Since v3.7.2 on two independent machines a very specific Git
repository fails in 9/10 cases on git-fsck due to an SHA1/memory
failures. This only occurs on a very specific repository and can be
reproduced stably on two independent laptops. Git mailing list ran
out of ideas and for me this looks like some very exotic kernel issue"
and bisected the failure to the backport of commit 53a59fc67f ("mm:
limit mmu_gather batching to fix soft lockups on !CONFIG_PREEMPT").
That commit itself is not actually buggy, but what it does is to make it
much more likely to hit the partial TLB invalidation case, since it
introduces a new case in tlb_next_batch() that previously only ever
happened when running out of memory.
The real bug is that the TLB gather virtual memory range setup is subtly
buggered. It was introduced in commit 597e1c3580 ("mm/mmu_gather:
enable tlb flush range in generic mmu_gather"), and the range handling
was already fixed at least once in commit e6c495a96c ("mm: fix the TLB
range flushed when __tlb_remove_page() runs out of slots"), but that fix
was not complete.
The problem with the TLB gather virtual address range is that it isn't
set up by the initial tlb_gather_mmu() initialization (which didn't get
the TLB range information), but it is set up ad-hoc later by the
functions that actually flush the TLB. And so any such case that forgot
to update the TLB range entries would potentially miss TLB invalidates.
Rather than try to figure out exactly which particular ad-hoc range
setup was missing (I personally suspect it's the hugetlb case in
zap_huge_pmd(), which didn't have the same logic as zap_pte_range()
did), this patch just gets rid of the problem at the source: make the
TLB range information available to tlb_gather_mmu(), and initialize it
when initializing all the other tlb gather fields.
This makes the patch larger, but conceptually much simpler. And the end
result is much more understandable; even if you want to play games with
partial ranges when invalidating the TLB contents in chunks, now the
range information is always there, and anybody who doesn't want to
bother with it won't introduce subtle bugs.
Ben verified that this fixes his problem.

In the previous QUERY_PAGES command version we used one command to get the
required amount of boot, init and post init pages. The new version uses the
op_mod field to specify whether the query is for the required amount of boot,
init or post init pages. In addition the output field size for the required
amount of pages increased from 16 to 32 bits.
In MANAGE_PAGES command the input_num_entries and output_num_entries fields
sizes changed from 16 to 32 bits and the PAS tables offset changed to 0x10.
In the pages request event the num_pages field also changed to 32 bits.
In the HCA-capabilities-layout the size and location of max_qp_mcg field has
been changed to support 24 bits.
This patch isn't compatible with firmware versions < 5; however, it turns out that the
first GA firmware we will publish will not support previous versions so this should be OK.

NULL pointer dereference in tg3 driver when !netdev || !netif_running(netdev)
condition is met and netdev is NULL. Then, the jump to the 'done' label
calls dev_close() with a netdevice that is NULL. Therefore, only call
dev_close() when we have a netdevice, but one that is not running.

ASoC: Fixes for v3.11
A few driver specific fixes here plus one core fix for a memory
corruption issue in DAPM initialisation which could lead to crashes.
This patch implements fallocate and punch hole support for Ceph kernel client.

ceph_check_caps() requests new max size only when there is Fw cap.
If we call check_max_size() while there is no Fw cap. It updates
i_wanted_max_size and calls ceph_check_caps(), but ceph_check_caps()
does nothing. Later when Fw cap is issued, we call check_max_size()
again. But i_wanted_max_size is equal to 'endoff' at this time, so
check_max_size() doesn't call ceph_check_caps() and we end up with
waiting for the new max size forever.
The fix is duplicate ceph_check_caps()'s "request max size" code in
check_max_size(), and make try_get_cap_refs() wait for the Fw cap
before retry requesting new max size.
This patch also removes the "endoff > (inode->i_size << 1)" check
in check_max_size(). It's useless because there is no corresponding
logic in ceph_check_caps().

I encountered below deadlock when running fsstress
wmtruncate work truncate MDS
--------------- ------------------ --------------------------
lock i_mutex
<- truncate file
lock i_mutex (blocked)
<- revoking Fcb (filelock to MIX)
send request ->
handle request (xlock filelock)
At the initial time, there are some dirty pages in the page cache.
When the kclient receives the truncate message, it reduces inode size
and creates some 'out of i_size' dirty pages. wmtruncate work can't
truncate these dirty pages because it's blocked by the i_mutex. Later
when the kclient receives the cap message that revokes Fcb caps, It
can't flush all dirty pages because writepages() only flushes dirty
pages within the inode size.
When the MDS handles the 'truncate' request from kclient, it waits
for the filelock to become stable. But the filelock is stuck in
unstable state because it can't finish revoking kclient's Fcb caps.
The truncate pagecache locking has already caused lots of trouble
for use. I think it's time simplify it by introducing a new mutex.
We use the new mutex to prevent concurrent truncate_inode_pages().
There is no need to worry about race between buffered write and
truncate_inode_pages(), because our "get caps" mechanism prevents
them from concurrent execution.

The invalidatepage code bails if it encounters a non-zero page offset. The
current logic that does is non-obvious with multiple if statements.
This should be logically and functionally equivalent.

The Tegra30 I2S driver was writing the AHUB interface parameters to the
playback path register rather than the capture path register. This
caused the capture parameters not to be configured at all, so if
capturing using non-HW-default parameters (e.g. 16-bit stereo rather
than 8-bit mono) the audio would be corrupted.
With this fixed, audio capture from an analog microphone works correctly
on the Cardhu board.

commit 56b765b79 ("htb: improved accuracy at high rates")
broke the "linklayer atm" handling.
tc class add ... htb rate X ceil Y linklayer atm
The linklayer setting is implemented by modifying the rate table
which is send to the kernel. No direct parameter were
transferred to the kernel indicating the linklayer setting.
The commit 56b765b79 ("htb: improved accuracy at high rates")
removed the use of the rate table system.
To keep compatible with older iproute2 utils, this patch detects
the linklayer by parsing the rate table. It also supports future
versions of iproute2 to send this linklayer parameter to the
kernel directly. This is done by using the __reserved field in
struct tc_ratespec, to convey the choosen linklayer option, but
only using the lower 4 bits of this field.
Linklayer detection is limited to speeds below 100Mbit/s, because
at high rates the rtab is gets too inaccurate, so bad that
several fields contain the same values, this resembling the ATM
detect. Fields even start to contain "0" time to send, e.g. at
1000Mbit/s sending a 96 bytes packet cost "0", thus the rtab have
been more broken than we first realized.

Drivers supporting NAPI should use a NAPI-specific function for receiving
packets. Hence netif_rx is changed to netif_receive_skb.
Furthermore netif_napi_del should be used in the probe and remove function
to clean up the NAPI resource information.

This reverts commit f83331bab1.
As the tests PPC64 (powernv platform) show, IOMMU pages are leaking
when transferring big amount of small packets (<=64 bytes),
"ping -f" and waiting for 15 seconds is the simplest way to confirm the bug.

It doesn't make sense to output a tunnel packet using the same
parameters that it was received with since that will generally
just result in the packet going back to us. As a result, userspace
assumes that the tunnel key is cleared when transitioning through
the switch. In the majority of cases this doesn't matter since a
packet is either going to a tunnel port (in which the key is
overwritten with new values) or to a non-tunnel port (in which
case the key is ignored). However, it's theoreticaly possible that
userspace could rely on the documented behavior, so this corrects
it.

If we get an error event really early in the driver setup sequence,

Oops. So try to avoid this.
Additionally with Haswell the transcoders are a separate bank of
registers from the pipes (4 transcoders, 3 pipes). In event of an
error, we want to be sure we have a complete and accurate picture of
the machine state, so record all the transcoders in addition to all
the active pipes.

drm/i915: convert PIPECONF to use transcoder instead of pipe
Based on the patch "drm/i915: Dump all transcoder registers on error"
from Chris Wilson:
v2: Rebase so that we don't try to be clever and try to figure out the
cpu transcoder from hw state. That exercise should be done when we
analyze the error state offline.
The actual bugfix is to not call intel_pipe_to_cpu_transcoder in the
error state capture code in case the pipes aren't fully set up yet.
v3: Simplifiy the err->num_transcoders computation a bit. While at it
make the error capture stuff save on systems without a display block.
v4: Fix fail, spotted by Jani.
v5: Completely new commit message, cc: stable.

Neil Brown reports that with libertas, my recent cfg80211
SME changes in commit ceca7b7121
("cfg80211: separate internal SME implementation") broke
libertas suspend because it we now asked it to disconnect
while already disconnected.
The problematic change is in cfg80211_disconnect() as it
previously checked the SME state and now calls the driver
disconnect operation unconditionally.
Fix this by checking if there's a current_bss indicating
a connection, and do nothing if not.
