Use iosf_mbi_modify instead of iosf_mbi_read + iosf_mbi_write so that
we keep the iosf_mbi_lock locked during the read-modify-write done to
reset the semaphore.

On my cherrytrail tablet with axp288 pmic, just doing a bunch of repeated
reads from the pmic, e.g. "i2cdump -y 14 0x34" would lookup the tablet in
1 - 3 runs guaranteed.
This seems to be causes by the cpu trying to enter C6 or C7 while we hold
the punit bus semaphore, at which point everything just hangs.
Avoid this by disallowing the CPU to enter C6 or C7 before acquiring the
punit bus semaphore.

iosf_mbi_available() returns false when an i2c bus is not using the
punit semaphore.
Also move the if (!iosf_mbi_available()) check to above the
dev_info, so that we do not repeat the dev_info on every probe
until iosf_mbi_available() returns true.

Some drivers may need to acquire P-Unit managed resources from interrupt
context, where they cannot call iosf_mbi_punit_acquire().
This commit adds a notifier chain which allows a driver to get notified
(in a process context) before other drivers start accessing the PMIC bus,
so that the driver can acquire any resources, which it may need during
the window the other driver is accessing the PMIC, before hand.

In order to make cursor updates actually safe wrt. watermark programming
we have to clear the legacy_cursor_update flag in the atomic state. That
will cause the regular atomic update path to do the necessary vblank
wait after the plane update if needed, otherwise the vblank wait would
be skipped and we'd feed the optimal watermarks to the hardware before
the plane update has actually happened.
To make the slow vs. fast path determination in
intel_legacy_cursor_update() a little simpler we can ignore the actual
visibility of the plane (which can only get computed once we've already
chosen out path) and instead we simply check whether the fb is being
set or cleared by the user. This means a fully clipped but logically
visible cursor will be considered visible as far as watermark
programming is concerned. We can do that for the cursor since it's a
fixed size plane and the clipped size doesn't play a role in the
watermark computation.
This should fix underruns that can occur when the cursor gets
enable/disabled or the size gets changed. Hopefully it's good enough
that only pure cursor movement and flips go through unthrottled.

Board Data File (BDF) is loaded upon driver boot-up procedure. The right
board data file is identified, among others, by device and sybsystem ids.
The problem, however, can occur when the (default) board data file cannot
fulfill with the vendor requirements and it is necessary to use a different
board data file.
To solve the issue QCA uses SMBIOS type 0xF8 to store Board Data File Name
Extension to specify the extension/variant name. The driver will take the
extension suffix into consideration and will load the right (non-default)
board data file if necessary.
If it is unnecessary to use extension board data file, please leave the
SMBIOS field blank and default configuration will be used.
Example:
If a default board data file for a specific board is identified by a string
"bus=pci,vendor=168c,device=003e,subsystem-vendor=1028,
subsystem-device=0310"
then the OEM specific data file, if used, could be identified by variant
suffix:
"bus=pci,vendor=168c,device=003e,subsystem-vendor=1028,
subsystem-device=0310,variant=DE_1AB"
If board data file name extension is set but board-2.bin does not contain
board data file for the variant, the driver will fallback to the default
board data file not to break backward compatibility.
This was first applied in commit f2593cb1b2 ("ath10k: Search SMBIOS for OEM
board file extension") but later reverted in commit 005c3490e9 ("Revert
"ath10k: Search SMBIOS for OEM board file extension"". This patch is now
otherwise the same as commit f2593cb1b2 except the regression fixed.

Sergey reported a might sleep warning triggered from the hpet resume
path. It's caused by the call to disable_irq() from interrupt disabled
context.
The problem with the low level resume code is that it is not accounted as a
special system_state like we do during the boot process. Calling the same
code during system boot would not trigger the warning. That's inconsistent
at best.
In this particular case it's trivial to replace the disable_irq() with
disable_hardirq() because this particular code path is solely used from
system resume and the involved hpet interrupts can never be force threaded.

Wanpeng Li reported that since the following commit:
acb04058de ("sched/clock: Fix hotplug crash")
... KVM always runs with unstable sched-clock even though KVM's
kvm_clock _is_ stable.
The problem is that we've tied clear_sched_clock_stable() to the TSC
state, and overlooked that sched_clock() is a paravirt function.
Solve this by doing two things:
- tie the sched_clock() stable state more clearly to the TSC stable
state for the normal (!paravirt) case.
- only call clear_sched_clock_stable() when we mark TSC unstable
when we use native_sched_clock().
The first means we can actually run with stable sched_clock in more
situations then before, which is good. And since commit:
12907fbb1a ("sched/clock, clocksource: Add optional cs::mark_unstable() method")
... this should be reliable. Since any detection of TSC fail now results
in marking the TSC unstable.

Introduce a trivial, mostly empty <linux/sched/cputime.h> header
to prepare for the moving of cputime functionality out of sched.h.
Update all code that relies on these facilities.

We don't actually need the full rculist.h header in sched.h anymore,
we will be able to include the smaller rcupdate.h header instead.
But first update code that relied on the implicit header inclusion.

Update code that relied on sched.h including various MM types for them.
This will allow us to remove the <linux/mm_types.h> include from <linux/sched.h>.
