Merge commit 'v2.6.30-rc1' into perfcounters/core

Browse Source 
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.
