## Description

In the Linux kernel, the following vulnerability has been resolved:  x86: shadow stacks: proper error handling for mmap lock  김영민 reports that shstk_pop_sigframe() doesn't check for errors from mmap_read_lock_killable(), which is a silly oversight, and also shows that we haven't marked those functions with "__must_check", which would have immediately caught it.  So let's fix both issues.
