mfd: rtsx_pcr: Disable interrupts before cancelling delayed works

This fixes a kernel panic when resuming from suspend to RAM.
Without this fix an interrupt hits after the delayed work is canceled
and thus requeues it. So we end up freeing an armed timer.

rename ARCH_BCM to ARCH_BCM_MOBILE (clocksource)

Currently ARCH_BCM has been used for Broadcom
Mobile V7 based SoCs. In order to allow other Broadcom
SoCs to also use mach-bcm directory and files, this patch
renames the original ARCH_BCM to ARCH_BCM_MOBILE, and
uses ARCH_BCM to define any Broadcom chip residing
in mach-bcm directory.

writeback: Fix data corruption on NFS

Commit 4f8ad655dbc8 "writeback: Refactor writeback_single_inode()" added
a condition to skip clean inode. However this is wrong in WB_SYNC_ALL
mode because there we also want to wait for outstanding writeback on
possibly clean inode. This was causing occasional data corruption issues
on NFS because it uses sync_inode() to make sure all outstanding writes
are flushed to the server before truncating the inode and with
sync_inode() returning prematurely file was sometimes extended back
by an outstanding write after it was truncated.

So modify the test to also check for pages under writeback in
WB_SYNC_ALL mode.

mac80211_hwsim: Fix NULL pointer dereference

mac80211_hwsim was crashing when receiving tx information from user
space. Crash happens because txi->rate_driver_data[0] is pointing to a
non valid memory address.

This code path is only used by wmediumd and wmediumd doesn't provide
multiple channel support, so we can pass the channel struct
(data2->channel) directly to mac80211_hwsim_monitor_ack function.

mac80211: move "bufferable MMPDU" check to fix AP mode scan

The check needs to apply to both multicast and unicast packets,
otherwise probe requests on AP mode scans are sent through the multicast
buffer queue, which adds long delays (often longer than the scanning
interval).

ARM: hisi: rename hi3xxx to hisi

Since some new Hisilicon SoCs are not named as hi3xxx, rename mach-hi3xxx
to mach-hisi instead. And the pronounciation of "hisi" is similar to the
chinese pronounciation of Hisilicon. So Hisilicon guys like this name.

ARCH_HI3xxx will be renamed later since other drivers are using it and
they are still in linux-next git tree. So rename ARCH_HI3xxx later.

ARM: fix footbridge clockevent device

The clockevents code was being told that the footbridge clock event
device ticks at 16x the rate which it actually does.  This leads to
timekeeping problems since it allows the clocksource to wrap before
the kernel notices.  Fix this by using the correct clock.
