The comment says it's using trialcs->mems_allowed as a temp variable but
it didn't match the code. Change the code to match the comment.
This fixes an issue when writing in cpuset.mems when a sub-directory
exists: we need to write several times for the information to persist:

The ESP code has been updated to generate a completely linear
AD SG list. This unfortunately broke authencesn which expects
the AD to be divided into at least three parts.
This patch fixes it to cope with the new format. Later we will
fix it properly to accept arbitrary input and not rely on the
input being linear as part of the AEAD conversion.

Since 906c55579a63 ("timekeeping: Copy the shadow-timekeeper over the
real timekeeper last") it has become possible on arm64 to:
- Obtain a CLOCK_MONOTONIC_COARSE or CLOCK_REALTIME_COARSE timestamp
via syscall.
- Subsequently obtain a timestamp for the same clock ID via VDSO which
predates the first timestamp (by one jiffy).
This is because arm64's update_vsyscall is deriving the coarse time
using the __current_kernel_time interface, when it should really be
using the timekeeper object provided to it by the timekeeping core.
It happened to work before only because __current_kernel_time would
access the same timekeeper object which had been passed to
update_vsyscall. This is no longer the case.

Upon receipt of SYNACK from the server, ipt_SYNPROXY first sends back an ACK to
finish the server handshake, then calls nf_ct_seqadj_init() to initiate
sequence number adjustment of forwarded packets to the client and finally sends
a window update to the client to unblock it's TX queue.
Since synproxy_send_client_ack() does not set synproxy_send_tcp()'s nfct
parameter, no sequence number adjustment happens and the client receives the
window update with incorrect sequence number. Depending on client TCP
implementation, this leads to a significant delay (until a window probe is
being sent).

Commit 77a3c6fd90c9 ("[media] vb2: Don't WARN when v4l2_buffer.bytesused
is 0 for multiplanar buffers") uses the __WARN() macro which isn't
defined when CONFIG_BUG isn't set. This introduces a compilation
breakage. Fix it by using WARN_ON() instead.
The commit was also broken in that it merged v1 of the patch while a new
v2 version had been submitted, reviewed and acked. Fix it by
incorporating the changes from v1 to v2.

It was possible for a synchronous update of the RX index in the error
case to get ahead of the asynchronous RX index update in the normal
case. Change the RX processing to preserve an RX completion order.
There were two error cases. First, if a buffer is not present to
receive data, there would be no queue entry to preserve the RX
completion order. Instead of dropping the RX frame, leave the RX frame
in the ring. Schedule RX processing when RX entries are enqueued, in
case there are RX frames waiting in the ring to be received.
Second, if a buffer is too small to receive data, drop the frame in the
ring, mark the RX entry as done, and indicate the error in the RX entry
length. Check for a negative length in the receive callback in
ntb_netdev, and count occurrences as rx_length_errors.

Pull MIPS fixes from Ralf Baechle:
"Another round of MIPS fixes for 4.2. No area does particularly stand
out but we have a two unpleasant ones:
- Kernel ptes are marked with a global bit which allows the kernel to
share kernel TLB entries between all processes. For this to work
both entries of an adjacent even/odd pte pair need to have the
global bit set. There has been a subtle race in setting the other
entry's global bit since ~ 2000 but it take particularly
pathological workloads that essentially do mostly vmalloc/vfree to
trigger this.
This pull request fixes the 64-bit case but leaves the case of 32
bit CPUs with 64 bit ptes unsolved for now. The unfixed cases
affect hardware that is not available in the field yet.
- Instruction emulation requires loading instructions from user space
but the current fast but simplistic approach will fail on pages
that are PROT_EXEC but !PROT_READ. For this reason we temporarily
do not permit this permission and will map pages with PROT_EXEC |
PROT_READ.

and the short log explains them well"

Currently the sh_cmt clocksource timer is disabled or enabled
unconditionally on clocksource suspend resp. resume, even if a
better clocksource is present (e.g. arch_sys_counter) and the
sh_cmt clocksource is not enabled.
As sh_cmt is a syscore device when its timer is enabled, this
may lead to a genpd.prepared_count imbalance in the presence of
PM Domains, which may cause a lock-up during reboot after s2ram.
During suspend:
- pm_genpd_prepare() is called for all non-syscore devices (incl.
sh_cmt), increasing genpd.prepared_count for each device,
- clocksource.suspend() is called for all clocksource devices,
- sh_cmt_clocksource_suspend() calls sh_cmt_stop(), which is a no-op
as the clocksource was not enabled.
During resume:
- clocksource.resume() is called for all clocksource devices,
- sh_cmt_clocksource_resume() calls sh_cmt_start(), which enables the
clocksource timer, and turns sh_cmt into a syscore device,
- pm_genpd_complete() is called for all non-syscore devices (excl.
sh_cmt now!), decreasing genpd.prepared_count for each device but
sh_cmt.
Now genpd.prepared_count of the PM Domain containing sh_cmt is
still 1 instead of zero. On subsequent suspend/resume cycles,
sh_cmt is still a syscore device, hence it's skipped for
pm_genpd_{prepare,complete}(), keeping the imbalance of
genpd.prepared_count at 1.
During reboot:
- platform_drv_shutdown() is called for any platform device that has
a driver with a .shutdown() method (only rcar-dmac on R-Car Gen2),
- platform_drv_shutdown() calls dev_pm_domain_detach(), which
calls genpd_dev_pm_detach(),
- genpd_dev_pm_detach() keeps calling pm_genpd_remove_device() until
it doesn't return -EAGAIN[*],
- If the device is part of the same PM Domain as sh_cmt,
pm_genpd_remove_device() always fails with -EAGAIN due to
genpd.prepared_count > 0.
- Infinite loop in genpd_dev_pm_detach()[*].
[*] Commit 93af5e9354432828 ("PM / Domains: Avoid infinite loops in
attach/detach code") already limited the number of loop iterations,
avoiding the lock-up.
To fix this, only disable or enable the clocksource timer on
clocksource suspend resp. resume if the clocksource was enabled.
This was tested on r8a7791/koelsch with the CPG Clock Domain:
- using arch_sys_counter as the clocksource, which is the default, and
which showed the problem,
- using sh_cmt as a clocksource ("echo ffca0000.timer > \
/sys/devices/system/clocksource/clocksource0/current_clocksource"),
which behaves the same as before.

Pull sound fixes from Takashi Iwai:
"The only bulk changes in this request is ABI updates for ASoC topology
API. It's a new API that was introduced in 4.2, and we'd like to
avoid ABI change after the release, so it's taken now. As there is no
real in-tree user for this API, it should be fairly safe.
Other than that, the usual small fixes are found in various drivers:
ASoC cs4265, rt5645, intel-sst, firewire, oxygen and HD-audio"

Clocks 0 to 31 are on CKENA, and not CKENB. The clock register names
were inadequately inverted. As a consequence, all clock operations were
happening on CKENB, because almost all but 2 clocks are on CKENA.
As the clocks were activated by the bootloader in the former tests, it
escaped the testing that the wrong clock gate was manipulated. The error
was revealed by changing the pxa3xx-nand driver to a module, where upon
unloading, the wrong clock was disabled in CKENB.
