Subject[GIT PULL] s390 update for 4.14 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 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

My test merge revealed a small conflict, easy to resolve:
