From: Arnd Bergmann <arnd@xxxxxxxx> While thinking about the changes to linux/mman.h in https://lore.kernel.org/all/20240923141943.133551-1-vincenzo.frascino@xxxxxxx/ I ended up trying to clean up the duplicate definitions in order to better see what's in there, and then I found a clash between two MAP_* flags. Here is my current state, lightly tested. Please have a look at the last patch in particular. Arnd Arnd Bergmann (5): asm-generic: cosmetic updates to uapi/asm/mman.h asm-generic: move MAP_* flags from mman-common.h to mman.h asm-generic: use asm-generic/mman-common.h on mips and xtensa asm-generic: use asm-generic/mman-common.h on parisc and alpha [RFC] mm: Remove MAP_UNINITIALIZED support Documentation/admin-guide/mm/nommu-mmap.rst | 10 +-- arch/alpha/include/uapi/asm/mman.h | 93 ++++++------------- arch/mips/include/uapi/asm/mman.h | 95 +++----------------- arch/parisc/include/uapi/asm/mman.h | 79 ++++------------- arch/powerpc/include/uapi/asm/mman.h | 11 +++ arch/sh/configs/rsk7264_defconfig | 1 - arch/sparc/include/uapi/asm/mman.h | 12 +++ arch/xtensa/include/uapi/asm/mman.h | 98 +++------------------ fs/binfmt_elf_fdpic.c | 3 +- include/linux/mman.h | 4 - include/uapi/asm-generic/mman-common.h | 31 +++---- include/uapi/asm-generic/mman.h | 17 ++++ include/uapi/linux/mman.h | 5 ++ mm/Kconfig | 22 ----- mm/nommu.c | 4 +- 15 files changed, 125 insertions(+), 360 deletions(-) -- 2.39.2 Cc: "Jason A.
