Author: Kirill A. Shutemov

The arm_global_timer provides unstable clock to sched_clock, it will
be selected by default instead of rockchip_timer. The same issue has
been fixed in rk3188.
So we must disable arm_global_timer to get the correct clocksource.

Switch 'requests' to be explicitly 64-bit and update BUILD_BUG_ON check to
use the size of "requests" instead of the hard-coded '32'.
That gives us a bit more room again for arch-specific requests as we
already ran out of space for x86 due to the hard-coded check.

Dear Linux folks,
I am trying to reduce the boot time of a standard Linux distribution
kernel. Currently, distributions – at least Debian und Ubuntu – enable
function tracing.

This RT load tracking doesn't replace current rt_avg because they are
not using same period and providing same function
current rt_avg uses sysctl_sched_time_avg to

What I don't see in this patch-set is removal of the current rt_avg
stuff.
And I didn't look closely enough; but are the root cfs and rt pelt
windows aligned? They really should be; otherwise you can't combine them
sanely.

It is seen that just enabling the TSC module triggers a HW_PEN IRQ
without any interaction with touchscreen by user. This results in first
suspend/resume sequence to fail as system immediately wakes up from
suspend as soon as HW_PEN IRQ is enabled in suspend handler due to
On AM335x, ti_am335x_tsc can wake up the system from suspend, mark the
IRQ as wakeup capable, so that device irq is not disabled during system
suspend.

This patch series fixes couple of issues wrt suspend/resume with TI AM335x
TSC driver. Disable and clear any pending IRQs before suspend, and
handle case where TSC wakeup would fail, if there were touch events
during suspend.

Rebase onto latest linux-next.
v1:https://lkml.org/lkml/2016/5/16/15
From: Grygorii Strashko
Prevent system suspend while user has finger on touch screen,
because TSC is wakeup source and suspending device while in use will
result in failure to disable the module.
This patch uses pm_stay_awake() and pm_relax() APIs to prevent and
resume system suspend as required.
tcp_rcv_space_adjust is called every time data is copied to user space,
introducing a tcp tracepoint for which could show us when the packet is
copied to user.
This could help us figure out whether there's latency in user process.
When a tcp packet arrives, tcp_rcv_established() will be called and
