nohz_full is only useful with isolcpus are also set, since
otherwise the scheduler has to run periodically to try to
determine whether to steal work from other cores.
Accordingly, when booting with nohz_full=xxx on the command
line, we should act as if isolcpus=xxx was also set, and set
(or extend) the isolcpus set to include the nohz_full cpus.

TIF_NOHZ is used by context_tracking to force syscall slow-path
on every task in order to track userspace roundtrips. As such,
it must be set on all running tasks.
It's currently explicitly inherited through context switches.
There is no need to do it in this fast-path though. The flag
could simply be set once for all on all tasks, whether they are
running or not.
Lets do this by setting the flag for the init task on early boot,
and let it propagate through fork inheritance.
While at it, mark context_tracking_cpu_set() as init code, we
only need it at early boot time.

Context tracking recursion can happen when an exception triggers
in the middle of a call to a context tracking probe.
This special case can be caused by vmalloc faults. If an access
to a memory area allocated by vmalloc happens in the middle of
context_tracking_enter(), we may run into an endless fault loop
because the exception in turn calls context_tracking_enter()
which faults on the same vmalloc'ed memory, triggering an
exception again, etc...
Some rare crashes have been reported so lets protect against
this with a recursion counter.

Currently KVM will clear the FPU bits in CR0.TS in the VMCS, and trap to
re-load them every time the guest accesses the FPU after a switch back into
the guest from the host.
This patch copies the x86 task switch semantics for FPU loading, with the
FPU loaded eagerly after first use if the system uses eager fpu mode,
or if the guest uses the FPU frequently.
In the latter case, after loading the FPU for 255 times, the fpu_counter
will roll over, and we will revert to loading the FPU on demand, until
it has been established that the guest is still actively using the FPU.
This mirrors the x86 task switch policy, which seems to work.

References (from Intel SDM):
"If the MP protocol has completed and a BSP is chosen, subsequent INITs (either

"If the processor is reset by asserting the INIT# pin, the x87 FPU state is not

"The state of the local APIC following an INIT reset is the same as it is after
a power-up or hardware reset, except that the APIC ID and arbitration ID
registers are not affected." [10.4.7.3: Local APIC State After an INIT Reset

This reverts commit 3a61e97563.
The Logitech TK820 seems to be affected by a firmware bug which
delays the sending of the keys (pressed, or released, which triggers
a key-repeat) while holding fingers on the touch sensor.
This behavior can be observed while using the mouse emulation mode
if the user moves the finger while typing (highly improbable though).
Holding the finger still while in the mouse emulation mode does
not trigger the key repeat problem.
So better keep things in their previous state to not have to
explain users that the new key-repeat bug they see is a "feature".
Furthermore, I noticed that I disabled the media keys whith

I think it is best to revert the patch, in all the current

'key' is set but never used in the first loop. So remove the set.
And indent the re-set of pm->last_key properly.

No functional change is introduced.
