add getcpu support

[Ulrich Drepper]

This patch adds support for the getcpu syscall and is meant to be
applied on top of the eventfd patch.  Even though x86-64 does not have
the syscall it is needed because x86 needs it for the compat support.

	* process.c (sys_getcpu): New function.
	* linux/syscall.h: Declare sys_getcpu.
	* linux/syscallent.h: Add entry for getcpu.
