8b3dfdaf0c ALSA: hda - Adjust speaker HPF and add LED support for HP Spectre 13
HP Spectre 13 has the IDT 92HD95 codec, and BIOS seems to set the
default high-pass filter in some "safer" range, which results in the
very soft tone from the built-in speakers in contrast to Windows.
Also, the mute LED control is missing, since 92HD95 codec still has no
HP-specific fixups for GPIO setups.

This patch adds these missing features: the HPF is adjusted by the
vendor-specific verb, and the LED is set up from a DMI string (but
with the default polarity = 0 assumption due to the incomplete BIOS on
the given machine).

0ffbce80c2 blk-mq: blk_mq_start_hw_queue() should use blk_mq_run_hw_queue()
Currently it calls __blk_mq_run_hw_queue(), which depends on the
CPU placement being correct. This means it's not possible to call
blk_mq_start_hw_queues(q) from a context that is correct for all
queues, leading to triggering the

WARN_ON(!cpumask_test_cpu(raw_smp_processor_id(), hctx->cpumask));

in __blk_mq_run_hw_queue().

8c9eb041cf MIPS: KVM: Fix memory leak on VCPU
kvm_arch_vcpu_free() is called in 2 code paths:

1) kvm_vm_ioctl()
       kvm_vm_ioctl_create_vcpu()
           kvm_arch_vcpu_destroy()
               kvm_arch_vcpu_free()
2) kvm_put_kvm()
       kvm_destroy_vm()
           kvm_arch_destroy_vm()
               kvm_mips_free_vcpus()
                   kvm_arch_vcpu_free()

Neither of the paths handles VCPU free. We need to do it in
kvm_arch_vcpu_free() corresponding to the memory allocation in
kvm_arch_vcpu_create().

b8e46d22dc This includes three patches from Oleg Nesterov. The first is a fix to a
race condition that happens between enabling/disabling syscall tracepoints
 and new process creations (the check to go into the ptrace path for a process
 can be set when it shouldn't, or not set when it should). Not a major bug
 but one that should be fixed and even applied to stable.
 
 The other two patches are cleanup/fixes that are not that critical, but
 for an -rc1 release would be nice to have. They both deal with syscall
 tracepoints.
 
 It also includes a patch to introduce a new macro for the TRACE_EVENT()
 format called __field_struct(). Originally, __field() was used to record
 any variable into a trace event, but with the addition of setting the
 "is signed" attribute, the check causes anything but a primitive variable
 to fail to compile. That is, structs and unions can't be used as they
 once were. When the "is signed" check was introduce there were only
 primitive variables being recorded. But that will change soon and it
 was reported that __field() causes build failures.
 
 To solve the __field() issue, __field_struct() is introduced to allow
 trace_events to be able to record complex types too.

8dcd598c74 misc: atmel_pwm: fix Kconfig symbols
AT91 symbols AT91SAM9263, AT91SAM9RL, and AT91SAM9G45 do not exist and this
patch changes them to their correct ARCH_* version.
These symbols are chosen instead of the SOC_* ones because this driver is not
converted to DT.
Anyway, the ATMEL_PWM symbol and the associated driver will be removed soon,
during the move to the PWM sub-system.

Its due to the fact that we call a potentially sleeping function from the bnx2fc
rcv path with preemption disabled (via the get_cpu call embedded in the per-cpu
variable stats lookup in bnx2fc_l2_rcv_thread.

Easy enough fix, we can just move the stats collection later in the function
where we are sure we won't preempt or sleep.  This also allows us to not have to
enable pre-emption when doing a per-cpu lookup, since we're certain not to get
rescheduled.

9172b763a7 bnx2fc: do not scan uninitialized lists in case of error.
In case of of error, the bnx2fc_cmd_mgr_alloc() function will call
the bnx2fc_cmd_mgr_free() to perform the cleanup.
The problem is that in one case the latter may try to scan
some not-yet initialized lists, resulting in a kernel panic.

This patch prevents this from happening by freeing the lists
before calling bnx2fc_cmd_mgr_free().

c2cbcf533a powerpc/module: Fix TOC symbol CRC
The commit 71ec7c55ed introduced the magic symbol ".TOC." for ELFv2 ABI.
This symbol is built manually and has no CRC value computed. A zero value
is put in the CRC section to avoid modpost complaining about a missing CRC.
Unfortunately, this breaks the kernel module loading when the kernel is
relocated (kdump case for instance) because of the relocation applied to
the kcrctab values.

This patch compute a CRC value for the TOC symbol which will match the one
compute by the kernel when it is relocated - aka '0 - relocate_start' done in
maybe_relocated called by check_version (module.c).

e2500be2b8 powerpc/powernv: Remove OPAL v1 takeover
In commit 27f4488872 "Add OPAL takeover from PowerVM" we added support
for "takeover" on OPAL v1 machines.

This was a mode of operation where we would boot under pHyp, and query
for the presence of OPAL. If detected we would then do a special
sequence to take over the machine, and the kernel would end up running
in hypervisor mode.

OPAL v1 was never a supported product, and was never shipped outside
IBM. As far as we know no one is still using it.

Newer versions of OPAL do not use the takeover mechanism. Although the
query for OPAL should be harmless on machines with newer OPAL, we have
seen a machine where it causes a crash in Open Firmware.

The code in early_init_devtree() to copy boot_command_line into cmd_line
was added in commit 817c21ad9a "Get kernel command line accross OPAL
takeover", and AFAIK is only used by takeover, so should also be
removed.

66b0686049 NFSv4: test SECINFO RPC_AUTH_GSS pseudoflavors for support
Fix nfs4_negotiate_security to create an rpc_clnt used to test each SECINFO
returned pseudoflavor. Check credential creation  (and gss_context creation)
which is important for RPC_AUTH_GSS pseudoflavors which can fail for multiple
reasons including mis-configuration.

Don't call nfs4_negotiate in nfs4_submount as it was just called by
nfs4_proc_lookup_mountpoint (nfs4_proc_lookup_common)

8445cd3528 NFS Return -EPERM if no supported or matching SECINFO flavor
Do not return RPC_AUTH_UNIX if SEINFO reply tests fail. This
prevents an infinite loop of NFS4ERR_WRONGSEC for non RPC_AUTH_UNIX mounts.

Without this patch, a mount with no sec= option to a server
that does not include RPC_AUTH_UNIX in the
SECINFO return can be presented with an attemtp to use RPC_AUTH_UNIX
which will result in an NFS4ERR_WRONG_SEC which will prompt the SECINFO
call which will again try RPC_AUTH_UNIX....

6edf96097b NFS: Don't mark the data cache as invalid if it has been flushed
Now that we have functions such as nfs_write_pageuptodate() that use
the cache_validity flags to check if the data cache is valid or not,
it is a little more important to keep the flags in sync with the
state of the data cache.
In particular, we'd like to ensure that if the data cache is empty, we
don't start marking it as needing revalidation.

f2467b6f64 NFS: Clear NFS_INO_REVAL_PAGECACHE when we update the file size
In nfs_update_inode(), if the change attribute is seen to change on
the server, then we set NFS_INO_REVAL_PAGECACHE in order to make
sure that we check the file size.
However, if we also update the file size in the same function, we
don't need to check it again. So make sure that we clear the
NFS_INO_REVAL_PAGECACHE that was set earlier.

18dd78c427 nfs: Fix cache_validity check in nfs_write_pageuptodate()
NFS_INO_INVALID_DATA cannot be ignored, even if we have a delegation.

We're still having some problems with data corruption when multiple
clients are appending to a file and those clients are being granted
write delegations on open.

To reproduce:

Client A:
vi /mnt/`hostname -s`
while :; do echo "XXXXXXXXXXXXXXX" >>/mnt/file; sleep $(( $RANDOM % 5 )); done

Client B:
vi /mnt/`hostname -s`
while :; do echo "YYYYYYYYYYYYYYY" >>/mnt/file; sleep $(( $RANDOM % 5 )); done

What's happening is that in nfs_update_inode() we're recognizing that
the file size has changed and we're setting NFS_INO_INVALID_DATA
accordingly, but then we ignore the cache_validity flags in
nfs_write_pageuptodate() because we have a delegation.  As a result,
in nfs_updatepage() we're extending the write to cover the full page
even though we've not read in the data to begin with.

66cb45aa41 block: add support for limiting gaps in SG lists
Another restriction inherited for NVMe - those devices don't support
SG lists that have "gaps" in them. Gaps refers to cases where the
previous SG entry doesn't end on a page boundary. For NVMe, all SG
entries must start at offset 0 (except the first) and end on a page
boundary (except the last).
