In Linux-3.9 we removed the mwait_idle() loop:
69fb3676df ("x86 idle: remove mwait_idle() and "idle=mwait" cmdline param")
The reasoning was that modern machines should be sufficiently
happy during the boot process using the default_idle() HALT
loop, until cpuidle loads and either acpi_idle or intel_idle
invoke the newer MWAIT-with-hints idle loop.
But two machines reported problems:
1. Certain Core2-era machines support MWAIT-C1 and HALT only.
MWAIT-C1 is preferred for optimal power and performance.
But if they support just C1, cpuidle never loads and
so they use the boot-time default idle loop forever.
2. Some laptops will boot-hang if HALT is used,
but will boot successfully if MWAIT is used.
This appears to be a hidden assumption in BIOS SMI,
that is presumably valid on the proprietary OS
where the BIOS was validated.
https://bugzilla.kernel.org/show_bug.cgi?id=60770
So here we effectively revert the patch above, restoring
the mwait_idle() loop. However, we don't bother restoring
the idle=mwait cmdline parameter, since it appears to add
no value.
Maintainer notes:
For 3.9, simply revert 69fb3676df
for 3.10, patch -F3 applies, fuzz needed due to __cpuinit use in
context For 3.11, 3.12, 3.13, this patch applies cleanly

plane->state->fb and plane->fb should always reference the same FB so
that atomic and legacy codepaths have the same view of display state.
However, there are some places in kernel code that directly set
plane->fb and neglect to update plane->state->fb. If we never do a
successful update through the atomic pipeline, the RmFB cleanup code
will look at the plane->state->fb pointer, which has never actually
been set to a legitimate value, and try to clean it up, leading to
BUG's.
Add a quick helper function to synchronize plane->state->fb with
plane->fb and call it everywhere the driver tries to manually set
plane->fb outside of the atomic pipeline. In this function, use
drm_atomic_set_fb_for_plane instead of writing plane->state->fb
directly to keep the reference count right.

drm/i915: Ensure plane->state->fb stays in sync with plane->fb
However this bug exists in mainline kernel too, so I created this to fix
it in mainline kernel.
A minor change is to use drm_atomic_set_fb_for_plane instead of update
reference count manually.

If the AP is confused and starts doing a CSA to the same channel,
just ignore that request instead of trying to act it out since it
was likely sent in error anyway.
In the case of the bug I was investigating the GO was misbehaving
and sending out a beacon with CSA IEs still included after having
actually done the channel switch.

As HT/VHT depend heavily on QoS/WMM, it's not a good idea to
let userspace add clients that have HT/VHT but not QoS/WMM.
Since it does so in certain cases we've observed (client is
using HT IEs but not QoS/WMM) just ignore the HT/VHT info at
this point and don't pass it down to the drivers which might
unconditionally use it.

When a beacon from the AP contains only the ECSA IE, and not a CSA IE
as well, this ECSA IE is not considered for calculating the CRC and
the beacon might be dropped as not being interesting. This is clearly
wrong, it should be handled and the channel switch should be executed.
Fix this by including the ECSA IE ID in the bitmap of interesting IEs.

Since moving the interface combination checks to mac80211, it's
broken because it now only considers interfaces with an assigned
channel context, so for example any interface that isn't active
can still be up, which is clearly an issue; also, in particular
P2P-Device wdevs are an issue since they never have a chanctx.
Fix this by counting running interfaces instead the ones with a
channel context assigned.

sc->nbcnvifs tracks assigned beacon slots, not enabled beacons.
Therefore, it cannot be used to decide if cur_conf->enable_beacon (bool)
should be updated, or if beacons have been enabled already.
With the current code (depending on the order of calls), beacons often
do not get enabled in an AP+STA setup.
To fix tracking of enabled beacons, convert cur_conf->enable_beacon to a
bitmask of enabled beacon slots.

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

Finally there are fixes for drivers that improperly compared struct clk

until we started generating unique struct clk pointers for every

Parentheses removal were left to the script. However, there were some
cases that were handled manually. In addition, handling pointer casts
were done manually too because not all replacements generated by the
script were suitable. When pointer casts on function arguments were
in the form:
<func>(...,(<type> *)&<expression>,...)
the replacements were discarded due to compilation warnings.

The function setup_timer combines the initialization of a timer with the
initialization of the timer's function and data fields.
So, this patch combines the multiline code for timer initialization using the function
setup_timer. This issue is identified via coccinelle script.
