Pull second set of s390 patches from Martin Schwidefsky: "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" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390/uaccess: rework uaccess code - fix locking issues s390/mm,tlb: optimize TLB flushing for zEC12 s390/mm,tlb: safeguard against speculative TLB creation s390/irq: Use defines for external interruption codes s390/irq: Add defines for external interruption codes s390/sclp: add timeout for queued requests kvm/s390: also set guest pages back to stable on kexec/kdump lcs: Add missing destroy_timer_on_stack() s390/tape: Add missing destroy_timer_on_stack() s390/tape: Use del_timer_sync() s390/3270: fix crash with multiple reset device requests s390/bitops,atomic: add missing memory barriers s390/zcrypt: add length check for aligned data to avoid overflow in msg-type 6 |
