[PATCH 14/14] arm: Convert arm to use read_persistent_clock
From: John Stultz
Date: Wed Mar 03 2010 - 22:58:54 EST
This patch converts the arm architecture to use the generic read_persistent_clock and update_persistent_clock interfaces, reducing the amount of arch specific code we have to maintain, and allowing for further cleanups in the future.
Also removes a direct xtime access, replacing it with current_kernel_time()
I have not built or tested this patch, so help from arch maintainers would be appreciated.
