Josh Poimboeuf 4ab980b5c3 objtool, panic: Disable SMAP in __stack_chk_fail()
[ Upstream commit 72c774aa9d1e16bfd247096935e7dae194d84929 ]

__stack_chk_fail() can be called from uaccess-enabled code.  Make sure
uaccess gets disabled before calling panic().

Fixes the following warning:

  kernel/trace/trace_branch.o: error: objtool: ftrace_likely_update+0x1ea: call to __stack_chk_fail() with UACCESS enabled
