Subject: [PATCH] objtool: Fix obsolete reference to CONFIG_X86_SMAP
Date: Wed, 1 Jun 2022 09:42:12 -0700 [thread overview]

CONFIG_X86_SMAP no longer exists. For objtool's purposes it has been
replaced with CONFIG_HAVE_UACCESS_VALIDATION.
Fixes: 03f16cd020eb ("objtool: Add CONFIG_OBJTOOL")
Reported-by: Lukas Bulwahn <lukas.bulwahn@gmail.com>
