Subject: [PATCH] x86/AMD/NB: Fix amd_set_subcaches() parameter type

This is under CAP_SYS_ADMIN, but Smatch complains that mask comes
from the user and the test for "mask > 0xf" can underflow.

The fix is simple: amd_set_subcaches() should hand down not an 'int'
but an 'unsigned long' like it was originally indended to do.
