Commit 92d5dd8cd6 ("nios2: update pt_regs") removed the nios2 specific
ucontext.h, replacing it with the version from asm-generic. Thus it's no
longer necessary to include ucontext.h in exported headers.

[I would really like an ACK on that one from dhowells; it appears to be
quite straightforward, but...]
MSG_PEEK isn't passed to ->recvmsg() via msg->msg_flags; as the matter of
fact, neither the kernel users of rxrpc, nor the syscalls ever set that bit
in there. It gets passed via flags; in fact, another such check in the same
function is done correctly - as flags & MSG_PEEK.
It had been that way (effectively disabled) for 8 years, though, so the patch
needs beating up - that case had never been tested. If it is correct, it's
-stable fodder.

It should be checking flags, not msg->msg_flags. It's ->sendmsg()
instances that need to look for that in ->msg_flags, ->recvmsg() ones
(including the other ->recvmsg() instance in that file, as well as
unix_dgram_recvmsg() this one claims to be imitating) check in flags.
Braino had been introduced in commit dcda13 ("caif: Bugfix - use MSG_TRUNC
in receive") back in 2010, so it goes quite a while back.

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
[PATCH] drm/mm: Fix support 4 GiB and larger ranges
driver fixes for new regressions since v3.19. Second are fixes to the
common clock divider type caused by recent changes to how we round clock
rates. This affects many clock drivers that use this common code.
Finally there are fixes for drivers that improperly compared struct clk
pointers (drivers must not deref these pointers). While some of these
drivers have done this for a long time, this did not cause a problem
until we started generating unique struct clk pointers for every
consumer. A new function, clk_is_match was introduced to get these
drivers working again and they are fixed up to no longer deref the
pointers themselves.

does not recognize the USB ID of the newer Slide Pro. This patch adds the
missing data structures so the newer remote will be recognized by the driver,
thereby allowing the TiVo, LiveTV, and Thumbs Up/Down buttons to be

There is an interesting bug in the vgic code, which manifests itself
when the KVM run loop has a signal pending or needs a vmid generation
rollover after having disabled interrupts but before actually switching
to the guest.
In this case, we flush the vgic as usual, but we sync back the vgic
state and exit to userspace before entering the guest. The consequence
is that we will be syncing the list registers back to the software model
using the GICH_ELRSR and GICH_EISR from the last execution of the guest,
potentially overwriting a list register containing an interrupt.
This showed up during migration testing where we would capture a state
where the VM has masked the arch timer but there were no interrupts,
resulting in a hung test.

The ARM architecture allows the caching of intermediate page table
levels and page table freeing requires a sequence like:
pmd_clear()
TLB invalidation
pte page freeing
With commit 5e5f6dc105 (arm64: mm: enable HAVE_RCU_TABLE_FREE logic),
the page table freeing batching was moved from tlb_remove_page() to
tlb_remove_table(). The former takes care of TLB invalidation as this is
also shared with pte clearing and page cache page freeing. The latter,
however, does not invalidate the TLBs for intermediate page table levels
as it probably relies on the architecture code to do it if required.
When the mm->mm_users < 2, tlb_remove_table() does not do any batching
and page table pages are freed before tlb_finish_mmu() which performs
the actual TLB invalidation.
This patch introduces __tlb_flush_pgtable() for arm64 and calls it from
the {pte,pmd,pud}_free_tlb() directly without relying on deferred page
table freeing.

A number of tx queue wake-up events went missing due to the
outlined scenario below. Start state is a pool of 16 tx URBs,
active tx_urbs count = 15, with the netdev tx queue open.
CPU #1 [softirq] CPU #2 [softirq]
start_xmit() tx_acknowledge()
................ ................
atomic_inc(&tx_urbs);
if (atomic_read(&tx_urbs) >= 16) {
-->
atomic_dec(&tx_urbs);
netif_wake_queue();
return;
<--
netif_stop_queue();
}
At the end, the correct state expected is a 15 tx_urbs count
value with the tx queue state _open_. Due to the race, we get
the same tx_urbs value but with the tx queue state _stopped_.
The wake-up event is completely lost.
Thus avoid hand-rolled concurrency mechanisms and use a proper
lock for contexts and tx queue protection.

The current driver assumes all RAPL domains within a CPU package
have the same energy unit. This is no longer true for HSW server
CPUs since DRAM domain has is own fixed energy unit which can be
different than the package energy unit enumerated by package
power MSR. In fact, the default HSW EP package power unit is 61uJ
whereas DRAM domain unit is 15.3uJ. The result is that DRAM power
consumption is counted 4x more than real power reported by energy
counters, similarly for max_energy_range_uj of DRAM domain.
This patch adds domain specific energy unit per cpu type, it allows
domain energy unit to override package energy unit if non zero.
Please see this document for details.

Dave could hit this assert consistently running btrfs/078. This is because
when we update the block groups we could truncate the free space, which would
try to delete the csums for that range and dirty the csum root. For this to
happen we have to have already written out the csum root so it's kind of hard to
hit this case. This patch fixes this by changing the logic to only write the
dirty block groups if the dirty_cowonly_roots list is empty. This will get us
the same effect as before since we add the extent root last, and will cover the
case that we dirty some other root again but not the extent root. Thanks,

My patch to properly count outstanding extents wrt MAX_EXTENT_SIZE introduced a
regression when re-dirtying already dirty areas. We have logic in split to make
sure we are taking the largest space into account but didn't have it for merge,
so it was sometimes making us think we were turning a tiny extent into a huge
extent, when in reality we already had a huge extent and needed to use the other
side in our logic. This fixes the regression that was reported by a user on

This problem is uncovered by a test case: http://patchwork.ozlabs.org/patch/244297.
Fsync() can report success when it actually doesn't. When we
have several threads running fsync() at the same tiem and in one fsync() we
get a transaction abortion due to some problems(in the test case it's disk
failures), and other fsync()s may return successfully which makes userspace
programs think that data is now safely flushed into disk.
It's because that after fsyncs() fail btrfs_sync_log() due to disk failures,
they get to try btrfs_commit_transaction() where it finds that there is
already a transaction being committed, and they'll just call wait_for_commit()
and return. Note that we actually check "trans->aborted" in btrfs_end_transaction,
but it's likely that the error message is still not yet throwed out and only after
wait_for_commit() we're sure whether the transaction is committed successfully.
This add the necessary check and it now passes the test.

inet_diag_dump_one_icsk() allocates too small skb.
Add inet_sk_attr_size() helper right before inet_sk_diag_fill()
so that it can be updated if/when new attributes are added.
iproute2/ss currently does not use this dump_one() interface,
this might explain nobody noticed this problem yet.

Originally, the thresholds used in the cpuidle driver for Armada SOCs
were temporarily chosen, leaving room for improvements.
This commit updates the thresholds for the Armada XP SOCs with values
that positively impact performances:
without patch with patch vendor kernel
- iperf localhost (gbit/sec) ~3.7 ~6.4 ~5.4
- ioping tmpfs (iops) ~163k ~206k ~179k
- ioping tmpfs (mib/s) ~636 ~805 ~699
The idle power consumption is negatively impacted (proportionally less
than the performance gain), and we are still performing better than
the vendor kernel here:
without patch with patch vendor kernel
- power consumption idle (W) ~2.4 ~3.2 ~4.4
- power consumption busy (W) ~8.6 ~8.3 ~8.6
There is still room for improvement regarding the value of these
thresholds, they were chosen to mimic the vendor kernel.
This patch only impacts Armada XP SOCs and was tested on Online Labs
C1 boards. A similar approach can be taken to improve the performances
of the Armada 370 and Armada 38x SOCs.
Thanks a lot to Thomas Petazzoni, Gregory Clement and Willy Tarreau
for the discussions and tips around this topic.

As stated in kernel/cpu_pm.c, "Platform is responsible for ensuring
that cpu_pm_enter is not called twice on the same CPU before
cpu_pm_exit is called.". In the current code in case of failure when
calling mvebu_v7_cpu_suspend, the function cpu_pm_exit() is never
called whereas cpu_pm_enter() was called just before.
This patch moves the cpu_pm_exit() in order to balance the
cpu_pm_enter() calls.

This reverts commit 2b995f6398.
Панов Андрей reported the following regression:
"Commit 2b995f6398 in 4.0.0-rc3 introduces a
nasty bug in transmit, corrupting packets.
To reproduce:
$ dd if=/dev/zero of=zeros bs=1M count=20
$ md5sum -b zeros
8f4e33f3dc3e414ff94e5fb6905cba8c *zeros
This checksum is correct.
Copy file "zeros" to another host with NFS, and it gets corrupted, checksum is
changed.
File should be big, small amounts of transmit isn't affected.
I use an i.MX6 Quad board.
If this commit is reverted, all works fine."
