Since 7300711e ("clockevents: broadcast fixup possible waiters"),
the timekeeping duty is assigned to the CPU that handles the tick
broadcast clock device by the time it is set in one shot mode.
This is an issue in full dynticks mode where the timekeeping duty
must stay handled by the boot CPU for now. Otherwise it prevents
secondary CPUs from offlining and this breaks
suspend/shutdown/reboot/...
As it appears there is no reason for this timekeeping duty to be
moved to the broadcast CPU, besides nothing prevent it from being
later re-assigned to another target, let's simply remove it.

Commit 316ad24830 ("sched/x86: Rewrite
set_cpu_sibling_map()") broke the construction of sibling maps,
which also broke the booted_cores accounting.
Before the rewrite, if smt was present, then each map was
updated for each smt sibling. After the rewrite only
cpu_sibling_mask gets updated, as the llc and core maps depend
on 'has_mc = x86_max_cores > 1' instead. This leads to problems
with topologies like the following
(qemu -smp sockets=2,cores=1,threads=2)
processor : 0
physical id : 0
siblings : 1 <= should be 2
core id : 0
cpu cores : 1
processor : 1
physical id : 0
siblings : 1 <= should be 2
core id : 0
cpu cores : 0 <= should be 1
processor : 2
physical id : 1
siblings : 1 <= should be 2
core id : 0
cpu cores : 1
processor : 3
physical id : 1
siblings : 1 <= should be 2
core id : 0
cpu cores : 0 <= should be 1
This patch restores the former construction by defining has_mc
as (has_smt || x86_max_cores > 1). This should be fine as there
were no (has_smt && !has_mc) conditions in the context.
Aso rename has_mc to has_mp now that it's not just for cores.

====================
Please pull this batch of fixes intended for the 3.10 stream...
Regarding the NFC bits, Samuel says:
"This is the first batch of NFC fixes for 3.10, and it contains:
- 3 fixes for the NFC MEI support:
* We now depend on the correct Kconfig symbol.
* We register an MEI event callback whenever we enable an NFC device,
otherwise we fail to read anything after an enable/disable cycle.
* We only disable an MEI device from its disable mey_phy_ops,
preventing useless consecutive disable calls.
- An NFC Makefile cleanup, as I forgot to remove a commented out line when
moving the LLCP code to the NFC top level directory."
As for the mac80211 bits, Johannes says:
"This time I have a fix from Stanislaw for a stupid mistake I made in the
auth/assoc timeout changes, a fix from Felix for 64-bit traffic counters
and one from Helmut for address mask handling in mac80211. I also have a
few fixes myself for four different crashes reported by a few people."
And Johannes says this about the iwlwifi bit:
"This fixes a brown paper-bag bug that we really should've caught in
review. More details in the changelog for the fix."
On top of that...
Arend van Spriel and Hante Meuleman cooperate to send a series of AP
and P2P mode fixes for brcmfmac.
Gabor Juhos corrects a register offset for AR9550, avoiding a bus
error.
Dan Carpenter provides a fixup to some dmesg output in the atmel
driver.
And, finally...
Felix Fietkau not only gives us a trio of small AR934x fixes, but
also refactors the ath9k aggregation session start/stop handling
(using the generic mac80211 support) in order to avoid a deadlock.
Please let me know if there are problems!

In tick_nohz_cpu_down_callback() if the cpu is the one handling
timekeeping, we must return something that stops the CPU_DOWN_PREPARE
notifiers and then start notify CPU_DOWN_FAILED on the already called
notifier call backs.
However traditional errno values are not handled by the notifier unless
these are encapsulated using errno_to_notifier().
Hence the current -EINVAL is misinterpreted and converted to junk after
notifier_to_errno(), leaving the notifier subsystem to random behaviour
such as eventually allowing the cpu to go down.
Fix this by using the standard NOTIFY_BAD instead.

The kvm_host.h header file doesn't handle well
inclusion when archs don't support KVM.
This results in build crashes for such archs when they
want to implement context tracking because this subsystem
includes kvm_host.h in order to implement the
guest_enter/exit APIs but it doesn't handle KVM off case.
To fix this, move the guest_enter()/guest_exit()
declarations and generic implementation to the context
tracking headers. These generic APIs actually belong to
this subsystem, besides other domains boundary tracking
like user_enter() et al.
KVM now properly becomes a user of this library, not the
other buggy way around.

While computing the cputime delta of dynticks CPUs,
we are mixing up clocks of differents natures:
* local_clock() which takes care of unstable clock
sources and fix these if needed.
* sched_clock() which is the weaker version of
local_clock(). It doesn't compute any fixup in case
of unstable source.
If the clock source is stable, those two clocks are the
same and we can safely compute the difference against
two random points.
Otherwise it results in random deltas as sched_clock()
can randomly drift away, back or forward, from local_clock().
As a consequence, some strange behaviour with unstable tsc
has been observed such as non progressing constant zero cputime.
(The 'top' command showing no load).
Fix this by only using local_clock(), or its irq safe/remote
equivalent, in vtime code.

The present code does not wait for the SCC to finish resetting itself
before trying to initialise the device. The result is that the SCC
interrupt sources become enabled (if they weren't already). This leads to
an early boot crash (unexpected interrupt) given CONFIG_EARLY_PRINTK. Fix
this by adding a delay. A successful reset disables the interrupt sources.
Also, after the reset for channel A setup, the SCC then gets a second
reset for channel B setup which leaves channel A uninitialised again. Fix
this by performing the reset only once.

The old code allowed very strange memory types. Now it works like
all the other video drivers: ioremap_wc is used unconditionally,
and MTRRs are set if PAT is unavailable (unless MTRR is disabled
by a module parameter).
UC, WB, and WT support is gone. If there are MTRR conflicts that prevent
addition of a WC MTRR, adding a non-conflicting MTRR is pointless; it's
better to just turn off MTRR support entirely.
As an added bonus, any MTRR added is freed on unload.
