Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky: "One additional new feature for 4.1, a new PRNG based on SHA-512 for the zcrypt driver. Two memory management related changes, the page table reallocation for KVM is removed, and with file ptes gone the encoding of page table entries is improved. And three bug fixes" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390/zcrypt: Introduce new SHA-512 based Pseudo Random Generator. s390/mm: change swap pte encoding and pgtable cleanup s390/mm: correct transfer of dirty & young bits in __pmd_to_pte s390/bpf: add dependency to z196 features s390/3215: free memory in error path s390/kvm: remove delayed reallocation of page tables for KVM kexec: allocate the kexec control page with KEXEC_CONTROL_MEMORY_GFP
