Merge tag 'metag-fixes-v4.0-1' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/metag
Pull arch/metag fix from James Hogan:
"This is just a single patch to fix the KSTK_EIP() and KSTK_ESP()
macros for metag which have always been erronously returning the PC
and stack pointer of the task's kernel context rather than from its
user context saved at entry from userland into the kernel, which
affects the contents of /proc/<pid>/maps and /proc/<pid>/stat"
