s390 patches for 4.9 merge window #1
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:
The new features and main improvements in this merge for v4.9
- Support for the UBSAN sanitizer
- Set HAVE_EFFICIENT_UNALIGNED_ACCESS, it improves the code in some places
- Improvements for the in-kernel fpu code, in particular the overhead for multiple consecutive in kernel fpu users is recuded
- Add a SIMD implementation for the RAID6 gen and xor operations
- Add RAID6 recovery based on the XC instruction
- The PCI DMA flush logic has been improved to increase the speed of the map / unmap operations
- The time synchronization code has seen some updates
And bug fixes all over the place.
