A series from Baoquan He cleans up the asm-generic/io.h to remove the ioremap_uc() definition from everything except x86, which still needs it for pre-PAT systems. This series notably contains a patch from Jiaxun Yang that converts MIPS to use asm-generic/io.h like every other architecture does, enabling future cleanups. Some of my own patches fix -Wmissing-prototype warnings in architecture specific code across several architectures. This is now needed as the warning is enabled by default. There are still some remaining warnings in minor platforms, but the series should catch most of the widely used ones make them more consistent with one another. David McKay fixes a bug in __generic_cmpxchg_local() when this is used on 64-bit architectures. This could currently only affect parisc64 and sparc64. Additional cleanups address from Linus Walleij, Uwe Kleine-König, Thomas Huth, and Kefeng Wang help reduce unnecessary inconsistencies between architectures. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmWeak8ACgkQYKtH/8kJ UidSiQ/+LL1WTO9d3Zx5HI0GGGjaIYpYs6jUNSf9Y5GPQiOrvjfEWj7CU11/4vxl GlQRpRyncYm8Eiz0Qu+aNxZFiiMah8Uful75yfbX8P1L4EPTbAYNDjkyNJrTjIAK jPK4sl8awIrapOeFUz++PsEj22R/4Is4f0mo+CqoCkL5RKlHe5oFdXzcwjmds4yK CvU6Ldn+M7FZ3EItMdjXaB3D3HS9uictFiO5JByZY8p+IcqgNRI/iHNnZIMsltJ+ XjDi0DG+x4jCj6teElSchw7AofE4OcNSP3xbR1PLKv6+xBLGYaAGZhNuPTz88eV/ Gj0loDQrrR5McGUfDBRHK9zN2Jd0O/FKnfh9kLOt1FLFyGPvC78Q/2HkpVCjbBr2 Pr1aqhLDHA+tGNSsThsV8RUa8/tiEnxAki43tfBFS3SEKhtQsTm2g1z4miwbE3p0 BJIrSgTqrP/SBq7a9z/thPrkzdZcNuA9FUETTbaMeUlJS51n1V9E5A1t7sOG7jaI vV/gbuR6FjvD49mTyQiOSCt3V4ygRqgN1Q+C4QM8WLqq2keUq0AhGodquv8F78in J3x2j2r27lHY7jKf8B0dua/JXAsF20u8qD6yDQ9ymkjt/MWhGXBgK0jpT7RTIuMS e2jmTywUVD4UohAcx3inkOojUhIJ5KDB0I4Pzv4zWcHNbyFNKcY= =4VQl -----END PGP SIGNATURE----- Merge tag 'asm-generic-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull asm-generic cleanups from Arnd Bergmann: "A series from Baoquan He cleans up the asm-generic/io.h to remove the ioremap_uc() definition from everything except x86, which still needs it for pre-PAT systems.
