Oliver O'Halloran 2400fd822f powerpc/asm: Mark cr0 as clobbered in mftb() ... The workaround for the CELL timebase bug does not correctly mark cr0 as being clobbered. This means GCC doesn't know that the asm block changes cr0 and might leave the result of an unrelated comparison in cr0 across the block, which we then trash, leading to basically random behaviour.
