[GIT PULL] s390 updates for v4.15
From: Heiko Carstens
Date: Mon Nov 13 2017 - 01:38:00 EST
Hello Linus,
since Martin is on vacation you get the s390 pull request for the v4.15
merge window this time from me.
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:
Besides a lot of cleanups and bug fixes these are the most important changes:
- A new regset for runtime instrumentation registers
- Hardware accelerated AES-GCM support for the aes_s390 module
- Support for the new CEX6S crypto cards
- Support for FORTIFY_SOURCE
- Addition of missing z13 and new z14 instructions to the in-kernel
disassembler
- Generate opcode tables for the in-kernel disassembler out of a simple text
file instead of having to manually maintain those tables
- Fast memset16, memset32 and memset64 implementations
- Removal of named saved segment support
- Hardware counter support for z14
- Queued spinlocks and queued rwlocks implementations for s390
- Use the stack_depth tracking feature for s390 BPF JIT
- A new s390_sthyi system call which emulates the sthyi (store hypervisor
information) instruction
- Removal of the old KVM virtio transport
- An s390 specific CPU alternatives implementation which is used in the new
spinlock code
You will see two trivial merge conflicts caused by the "SPDX GPL-2.0 license"
commit and the removal of s390 specific header files:
arch/s390/include/asm/rwsem.h
arch/s390/include/uapi/asm/kvm_virtio.h
The resolution is to simply remove those files.
Thanks,
Heiko
