Subject: [GIT PULL] s390 updates for v4.15
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
