Modified files:
	arch/parisc/kernel: signal.c 

Log message:
Signal handlers seem to sort of work now (provided the stack is
executable).  sigcontext restoring is probably still broken though.

For some reason I need to pad the trampoline with some nops to make it
work.  This might just be cargo culting.

Also I'm not sure if we need the assembly for cache flushing or
should/could just fix __flush_icache_range.
