powerpc: Fixup oddity in entry_32.S
When I "fixed" the CONFIG_TRACE_IRQFLAGS case on interrupt entry, I screwed up a little bit with the test for user space vs. kernel. The code is fine, there's just some dead code around it. I basically removed the test and always create the added stack frame whether coming from user or kernel since in any case we do need to save a bunch of volatile registers or bad things would happen (we can take page faults in the kernel for example).
