Subject: [PATCH v2 00/20] localize xtime_lock usage to kernel/time/
This patchseries cleans up the unnecessary export of xtime_lock
to arch code. After this series is applied its only used in
kernel/time/
- move do_timer() into kernel/time/timekeeping.c
and provide a version which properly takes the xtime_lock.
- get_jiffies_64() is moved to kernel/time/jiffies.c
- provide get_xtime_and_monotonic_offset() for use in
kernel/hrtimer.c and use that.
- make all arch code use the new xtime_update() function.
- finally moves do_timer() and xtime_lock into a header file
private to kernel/time
ChangeLog:
for v2:
- add maintainer CC to all the arch commits.
- improved commit logs based on tglx comments.
- also deals with kernel/time.c and kernel/hrtimer.c
by moving get_jiffies_64() and providing a function
for kernel/hrtimer.c to use.
- fix kdoc comment for xtime_update.

Torben Hohn (20):
move do_timer() from kernel/timer.c into kernel/time/timekeeping.c
move get_jiffies_64 to kernel/time/jiffies.c
provide get_xtime_and_monotonic_offset() and use it in hrtimer.c
provide xtime_update() which does not require the caller to hold xtime_lock
alpha: change do_timer() to xtime_update()
arm: switch from do_timer() to xtime_update()
arm/mach-clps711x: switch do_timer() to xtime_update()
blackfin: switch from do_timer() to xtime_update()
cris/arch-v10: switch do_timer() to xtime_update()
cris/arch-v32: switch do_timer() to xtime_update()
frv: switch do_timer() to xtime_update()
h8300: switch do_timer() to xtime_update()
ia64: switch do_timer() to xtime_update()
m32r: switch from do_timer() to xtime_update()
m68k: switch do_timer() to xtime_update()
mn10300: switch do_timer() to xtimer_update()
parisc: switch do_timer() to xtime_update()
sparc: switch do_timer() to xtime_update()
xtensa: switch do_timer() to xtime_update()
make do_timer() and xtime_lock private to the timer code
