[PATCH 0/5] asm-generic: clean up asm/mman.h

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

While thinking about the changes to linux/mman.h in
https://lore.kernel.org/all/20240923141943.133551-1-vincenzo.frascino@arm.com/
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 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
