27) 2b97aaf74ed5 ("minmax.h: remove some #defines that are only

2 prerequisite commits that adjust users of MIN and MAX macros (to
prevent compilation issues):
13) 4477b39c32fd ("minmax: add a few more MIN_T/MAX_T users")
17) cb04e8b1d2f2 ("minmax: don't use max() in situations that want a C
    constant expression")

1 additional commit introduced to resolve a build failures during the
backport:
16) lib: zstd: drop local MIN/MAX macros in favor of generic ones

The primary motivation is to bring in commit (8).
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.
