Merge commit 'v2.6.30-rc1' into perfcounters/core
Conflicts: arch/powerpc/include/asm/systbl.h arch/powerpc/include/asm/unistd.h include/linux/init_task.h Merge reason: the conflicts are non-trivial: PowerPC placement of sys_perf_counter_open has to be mixed with the new preadv/pwrite syscalls. Signed-off-by: Ingo Molnar <mingo@elte.hu>
