[PATCH 0/7 5.10.y] Cherry pick of minmax.h commits from 5.15.y

[Eliav Farber <farbere@amazon.com>]

This series backports seven commits from v5.15.y that update minmax.h
and related code:

 - ed6e37e30826 ("tracing: Define the is_signed_type() macro once")
 - 998f03984e25 ("minmax: sanity check constant bounds when clamping")
 - d470787b25e6 ("minmax: clamp more efficiently by avoiding extra
   comparison")
 - 1c2ee5bc9f11 ("minmax: fix header inclusions")
 - d53b5d862acd ("minmax: allow min()/max()/clamp() if the arguments
   have the same signedness.")
 - 7ed91c5560df ("minmax: allow comparisons of 'int' against 'unsigned
   char/short'")
 - 22f7794ef5a3 ("minmax: relax check to allow comparison between
   unsigned arguments and signed constants")

The main motivation is commit d53b5d862acd, which removes the strict
type check in min()/max() when both arguments have the same signedness.
Without this, kernel 5.10 builds can emit warnings that become build
failures when -Werror is used.

Additionally, commit ed6e37e30826 from tracing is required as a
dependency; without it, compilation fails.
