parents390: TASK_SIZE for kernel threads (diff)
Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull more s390 updates from Martin Schwidefsky: "Next to the usual bug fixes (including the TASK_SIZE fix), there is one larger crypto item. It allows to use protected keys with the in-kernel crypto API The protected key support has two parts, the pkey user space API to convert key formats and the paes crypto module that uses a protected key instead of a standard AES key" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390: TASK_SIZE for kernel threads s390/crypt: Add protected key AES module s390/dasd: fix spelling mistake: "supportet" -> "supported" s390/pkey: Introduce pkey kernel module s390/zcrypt: export additional symbols s390/zcrypt: Rework CONFIG_ZCRYPT Kconfig text. s390/zcrypt: Cleanup leftover module code. s390/nmi: purge tlbs after control register validation s390/nmi: fix order of register validation s390/crypto: Add PCKMO inline function s390/zcrypt: Enable request count reset for cards and queues. s390/mm: use _SEGMENT_ENTRY_EMPTY in the code s390/chsc: Add exception handler for CHSC instruction s390: opt into HAVE_COPY_THREAD_TLS s390: restore address space when returning to user space s390: rename CIF_ASCE to CIF_ASCE_PRIMARY
