objtool warning from next-20230125

[Paul E. McKenney]

Hello!

I have started seeing these objtool warnings from a wide variety of
KASAN-enabled rcutorture-related test scenarios in next-20230125.  It has
been awhile since I tested -next, so I am not yet sure where this started.

vmlinux.o: warning: objtool: __asan_memset+0x34: call to __memset() with UACCESS enabled
vmlinux.o: warning: objtool: __asan_memmove+0x4d: call to __memmove() with UACCESS enabled
vmlinux.o: warning: objtool: __asan_memcpy+0x4d: call to __memcpy() with UACCESS enabled

As usual, should I be worried?

							Thanx, Paul
