Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull more s390 updates from Heiko Carstens: "This includes one bpf/jit bug fix where the jit compiler could sometimes write generated code out of bounds of the allocated memory area. The rest of the patches are only cleanups and minor improvements" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390/irq: reduce size of external interrupt handler hash array s390/compat,uid16: use current_cred() s390/ap_bus: use and-mask instead of a cast s390/ftrace: avoid pointer arithmetics with function pointers s390: make various functions static, add declarations to header files s390/compat signal: add couple of __force annotations s390/mm: add __releases()/__acquires() annotations to gmap_alloc_table() s390: keep Kconfig sorted s390/irq: rework irq subclass handling s390/irq: use hlists for external interrupt handler array s390/dumpstack: convert print_symbol to %pSR s390/perf: Remove print_hex_dump_bytes() debug output s390: update defconfig s390/bpf,jit: fix address randomization
