Subject: linux-next: build warning after merge of the vfs tree

Hi all,

After merging the vfs tree, today's linux-next build (x86_64 allmodconfig)
produced this warning:

lib/strnlen_user.o: warning: objtool: strnlen_user()+0xf3: call to do_strnlen_user() with UACCESS enabled
lib/strncpy_from_user.o: warning: objtool: strncpy_from_user()+0x188: call to do_strncpy_from_user() with UACCESS enabled

Introduced by commit

  e33ea6e5ba6a ("x86/uaccess: Use pointer masking to limit uaccess speculation")

-- 
Cheers,
Stephen Rothwell
