Hi Thomas,

I've merged the latest Linus tree into the range-hrtimer tree (there
were a few trivial conflicts due to the many patches in the first part
of the merge window) and pushed it to the git-repo.



The following changes since commit 2e532d68a2b3e2aa6b19731501222069735c741c:
Linus Torvalds (1):
{pci,pnp} quirks.c: don't use deprecated print_fn_descriptor_symbol()

are available in the git repository at:

git://git.kernel.org/pub/scm/linux/kernel/git/arjan/linux-2.6-hrtimer.git for-linus

The range-hrtimer series significantly improves the quality of behavior of the select()
and poll() system calls, as well as using timer ranges to optimize the power impact
of these timers.

Arjan van de Ven (29):
select: Introduce a hrtimeout function
select: switch select() and poll() over to hrtimers
hrtimer: add abstraction functions for accessing the "expires" member
hrtimer: convert kvm to the new hrtimer apis
hrtimer: convert timerfd to the new hrtimer apis
hrtimer: convert net::sched_cbq to the new hrtimer apis
hrtimer: convert kernel/* to the new hrtimer apis
hrtimer: convert powerpc/oprofile to the new hrtimer apis
hrtimer: convert kvm-ia64 to the new hrtimer apis
hrtimer: convert s390 to the new hrtimer apis
hrtimer: convert sound/ to the new hrtimer apis
hrtimer: rename the "expires" struct member to avoid accidental usage
hrtimer: turn hrtimers into range timers
hrtimer: create a "timer_slack" field in the task struct
hrtimer: make select() and poll() use the hrtimer range feature
hrtimer: fix build bug found by Ingo
hrtimer: another build fix
hrtimer: add a hrtimer_start_range() function
hrtimer: incorporate feedback from Peter Zijlstra
hrtimer: show the timer ranges in /proc/timer_list
hrtimer: fix signed/unsigned bug in slack estimator
hrtimer: make the nanosleep() syscall use the per process slack
hrtimer: make the futex() system call use the per process slack value
hrtimer: peek at the timer queue just before going idle
select: fix alpha OSF wrapper
rangetimer: fix x86 build failure for the !HRTIMERS case
rangetimer: fix BUG_ON reported by Ingo
rangetimers: fix the bug reported by Ingo for real
Merge commit 'linus/master' into merge-linus

Stephen Rothwell (1):
DECLARE_PER_CPU needs linux/percpu.h

Thomas Gleixner (3):
select: add a timespec_add_safe() function
select: add poll_select_set_timeout() and poll_select_copy_remaining() helpers
select: add a poll specific struct to the restart_block union
