Tracepoint for dynamic PLE window, fired on every potential change.
Signed-off-by: Radim Krčmář <rkrcmar@redhat.com>

Window is increased on every PLE exit and decreased on every sched_in.
The idea is that we don't want to PLE exit if there is no preemption
going on.
We do this with sched_in() because it does not hold rq lock.
There are two new kernel parameters for changing the window:
ple_window_grow and ple_window_shrink
ple_window_grow affects the window on PLE exit and ple_window_shrink
does it on sched_in; depending on their value, the window is modifier
like this: (ple_window is kvm_intel's global)
ple_window_shrink/ |
ple_window_grow | PLE exit | sched_in
-------------------+--------------------+---------------------
< 1 | = ple_window | = ple_window
< ple_window | *= ple_window_grow | /= ple_window_shrink
otherwise | += ple_window_grow | -= ple_window_shrink
A third new parameter, ple_window_max, controls the maximal ple_window;
it is internally rounded down to a closest multiple of ple_window_grow.
VCPU's PLE window is never allowed below ple_window.

EPT misconfig handler in kvm will check which reason lead to EPT
misconfiguration after vmexit. One of the reasons is that an EPT
paging-structure entry is configured with settings reserved for
future functionality. However, the handler can't identify if
paging-structure entry of reserved bits for 1-GByte page are
configured, since PDPTE which point to 1-GByte page will reserve
bits 29:12 instead of bits 7:3 which are reserved for PDPTE that
references an EPT Page Directory. This patch fix it by reserve
bits 29:12 for 1-GByte page.

Increase max i2c bus frequency beyond the default for faster
data transfers. According to the manual, these faster speeds are
only available when the board is wired up the right way. In this case,
the vendor kernel has run at this speed for a long time.
sda-delay is needed for talking to RTC on PMIC, otherwise the i2c
controller never sees an ACK. Strangely the other PMIC i2c slave (the
main one) works fine even without this delay. I Chose value 100 to
match the vendor kernel.
