Merge branch 'core/signal' into perfcounters/core

This is necessary to avoid the conflict of syscall numbers.

Conflicts:
	arch/x86/ia32/ia32entry.S
	arch/x86/include/asm/unistd_32.h
	arch/x86/include/asm/unistd_64.h

Fixes up the borked syscall numbers of perfcounters versus
preadv/pwritev as well.
