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" * tag 'metag-fixes-v4.0-1' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/metag: metag: Fix KSTK_EIP() and KSTK_ESP() macros
