In mainline, this change allows min()/max()/clamp() to accept mixed argument types when both share the same signedness. Backported patches to v5.10.y that use such forms trigger compiler warnings, which in turn cause build failures when -Werror is enabled. Originaly I aligned 5.10.y to 5.15.y, but David Laight commented that I need to pick up the later changes (from Linus) as well. Andy Shevchenko (2): minmax: deduplicate __unconst_integer_typeof() minmax: fix header inclusions Bart Van Assche (1): overflow, tracing: Define the is_signed_type() macro once David Laight (11): minmax: allow min()/max()/clamp() if the arguments have the same signedness. minmax: fix indentation of __cmp_once() and __clamp_once() minmax: allow comparisons of 'int' against 'unsigned char/short' minmax: relax check to allow comparison between unsigned arguments and signed constants minmax.h: add whitespace around operators and after commas minmax.h: update some comments minmax.h: reduce the #define expansion of min(), max() and clamp() minmax.h: use BUILD_BUG_ON_MSG() for the lo < hi test in clamp() minmax.h: move all the clamp() definitions after the min/max() ones minmax.h: simplify the variants of clamp() minmax.h: remove some #defines that are only expanded once Eliav Farber (1): lib: zstd: drop local MIN/MAX macros in favor of generic ones Herve Codina (1): minmax: Introduce {min,max}_array() Jason A.
