Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rkuo/linux-hexagon-kernel
Pull Hexagon updates from Richard Kuo: "Mostly cleanups for compilation with allmodconfig and some other miscellaneous fixes" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rkuo/linux-hexagon-kernel: Hexagon: update CR year for elf.h Hexagon: remove SP macro Hexagon: set ELF_EXEC_PAGESIZE to PAGE_SIZE Hexagon: set the e_flags in user regset view for core dumps Hexagon: fix atomic_set Hexagon: add screen_info for VGA_CONSOLE hexagon: correct type on pgd copy smp, hexagon: kill SMP single function call interrupt arch: hexagon: include: asm: add generic macro 'mmiowb' in "io.h" arch: hexagon: kernel: hexagon_ksyms.c: export related symbols which various modules need arch: hexagon: kernel: reset.c: use function pointer instead of function for pm_power_off and export it arch: hexagon: include: asm: add "vga.h" in Kbuild arch: hexagon: include: asm: Kbuild: add generic "serial.h" in Kbuild arch: hexagon: include: uapi: asm: setup.h add swith macro __KERNEL__ arch: hexagon: include: asm: add prefix "hvm[ci]_" for all enum members in "hexagon_vm.h" arch: hexagon: Kconfig: add HAVE_DMA_ATTR in Kconfig and remove "linux/dma-mapping.h" from "asm/dma-mapping.h" arch: hexagon: kernel: add export symbol function __delay() hexagon: include: asm: kgdb: extend DBG_MAX_REG_NUM for "cs0/1" hexagon: kernel: kgdb: include related header for pass compiling. hexagon: kernel: remove useless variables 'dn', 'r' and 'err' in time_init_deferred() in "time.c"
