![]() Some G3 CPUs can crash in funny way if a store from an FPU register instruction is executed on a register that has never been initialized since power on. This patch fixes it by making sure all FP registers have been properly initialized at kernel boot and when waking from sleep. It also makes the code that decides wether HID0_BTIC and HID0_DPM are allowed on a given CPU smarter (it can actually _clear_ them now if they are not allowed instead of just setting them when they are allowed in case the firmware got them wrong) Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org> |
