Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky: "Bug fixes, small improvements and one notable change: the system call table and the unistd.h header are now generated automatically with a shell script from a text file" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390/decompressor: discard __ksymtab and .eh_frame sections s390: fix handling of -1 in set{,fs}[gu]id16 syscalls s390/tools: generate header files in arch/s390/include/generated/ s390/syscalls: use generated syscall_table.h and unistd.h header files s390/syscalls: add Makefile to generate system call header files s390/syscalls: add syscalltbl script s390/syscalls: add system call table s390/decompressor: swap .text and .rodata.compressed sections s390/sclp: fix .data section specification s390/ipl: avoid usage of __section(.data) s390/head: replace hard coded values with constants s390/disassembler: add generated gen_opcode_table tool to .gitignore s390: remove bogus system call table entries s390/kprobes: remove duplicate includes s390/dasd: Remove dead return code checks s390/dasd: Simplify code s390/vdso: revise CFI annotations of vDSO functions s390/kernel: emit CFI data in .debug_frame and discard .eh_frame sections
