Subject[GIT PULL] s390 patches for the 3.15 merge window #2
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 second part of Heikos uaccess rework, the page table walker for uaccess
is now a thing of the past (yay!)

The code change to fix the theoretical TLB flush problem allows us to
add a TLB flush optimization for zEC12, this machine has new instructions
that allow to do CPU local TLB flushes for single pages and for all pages
of a specific address space.

Plus the usual bug fixing and some more cleanup.

Christian Borntraeger (1):
kvm/s390: also set guest pages back to stable on kexec/kdump

Gerald Schaefer (1):
s390/sclp: add timeout for queued requests

Heiko Carstens (2):
s390/bitops,atomic: add missing memory barriers
s390/uaccess: rework uaccess code - fix locking issues

Ingo Tuchscherer (1):
s390/zcrypt: add length check for aligned data to avoid overflow in msg-type 6

Martin Schwidefsky (3):
s390/3270: fix crash with multiple reset device requests
s390/mm,tlb: safeguard against speculative TLB creation
s390/mm,tlb: optimize TLB flushing for zEC12

Thomas Gleixner (3):
s390/tape: Use del_timer_sync()
s390/tape: Add missing destroy_timer_on_stack()
lcs: Add missing destroy_timer_on_stack()

Thomas Huth (2):
s390/irq: Add defines for external interruption codes
s390/irq: Use defines for external interruption codes
