-bit architectures that make use of the generic cmpxchg. Signed-off-by: Darius Rad --- It does not appear that this is relevant to architectures that are in the kernel tree, since the generic cmpxchg is only ever used by some 32-bit architectures. This does impact the RISC-V architecture

[PATCH] include/linux/atomic.h: include asm-generic/atomic-long.h after asm-generic/atomic64.h

Move the include of asm-generic/atomic-long.h to after the conditional include of asm-generic/atomic64.h. This is necessary if CONFIG_GENERIC_ATOMIC64 is y and BITS_PER_LONG == 64, because atomic-long.h uses functions declared in atomic64.h. Signed-off-by: Darius Rad --- It does not appear

-off-by: Darius Rad --- It does not appear that this is relevant to architectures that are in the kernel tree (i.e., no architectures use GENERIC_ATOMIC64 on 64-bit). It is relevant, however, to certain combinations of options for the RISC-V architecture currently in development. Patch generated
