Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky:
"The first part of the s390 updates for 4.14:
- Add machine type 0x3906 for IBM z14
- Add IBM z14 TLB flushing improvements for KVM guests
- Exploit the TOD clock epoch extension to provide a continuous TOD
clock afer 2042/09/17
- Add NIAI spinlock hints for IBM z14
- Rework the vmcp driver and use CMA for the respone buffer of z/VM
CP commands
- Drop some s390 specific asm headers and use the generic version
- Add block discard for DASD-FBA devices under z/VM
- Add average request times to DASD statistics
- A few of those constify patches which seem to be in vogue right now
- Cleanup and bug fixes"
