Hi Linus,
please pull from the 'for-linus' branch of
git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git for-linus
to receive the following updates:
Another two bug fixes for 4.7:
- The revert of patch which removed boot information for systems using an
intermediate boot kernel, e.g. the SLES12 grub setup.
- A fix for an incorrect inline assembly constraint that causes broken
code to be generated with gcc 4.8.5.
