	gdb/
	* regcache.c (get_thread_arch_regcache): If creating a regcache for
	null_ptid, assume and allow a NULL address space, instead of
	asking the target for the ptid's address space.
	* infrun.c (ptid_is_pid): Remove assertion.

	gdb/testsuite/
	* gdb.base/maint.exp: Test that "maint print registers" works
	without a running program.
