Subject: [PATCH v3 00/19 5.15.y] Backport minmax.h updates from v6.17-rc7
This series backports 19 patches to update minmax.h in the 5.15.y branch,
aligning it with v6.17-rc7.
The ultimate goal is to synchronize all longterm branches so that they
include the full set of minmax.h changes.
6.12.y was already backported and changes are part of v6.12.49.
6.6.y was already backported and changes are part of v6.6.109.
6.1.y was already backported and changes are currently in the 6.1-stable
tree.
The key motivation is to bring in commit d03eba99f5bf ("minmax: allow
min()/max()/clamp() if the arguments have the same signedness"), which
is missing in kernel 5.10.y.
In mainline, this change enables min()/max()/clamp() to accept mixed
argument types, provided both have the same signedness. Without it,
backported patches that use these forms may trigger compiler warnings,
which escalate to build failures when -Werror is enabled.
Changes in v3:
- Fix fs/erofs/zdata.h in patch 06/19 to use MIN_T instead of min_t to
fix build on the following patch (07/19):

cc1: all warnings being treated as errors
- Increase test coverage using `make allyesconfig` and
`make allmodconfig` for arm64, arm, x86_64 and i386 architectures.
Changes in v2:
- Fix the order of patches 6 - 10 according to order in mainline branch.
- Use same style of [ Upstream commit <HASH> ] in all patches.
Andy Shevchenko (1):
minmax: deduplicate __unconst_integer_typeof()
David Laight (8):
minmax: fix indentation of __cmp_once() and __clamp_once()
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
Herve Codina (1):
minmax: Introduce {min,max}_array()
Linus Torvalds (8):
minmax: avoid overly complicated constant expressions in VM code
minmax: add a few more MIN_T/MAX_T users
minmax: simplify and clarify min_t()/max_t() implementation
minmax: make generic MIN() and MAX() macros available everywhere
minmax: don't use max() in situations that want a C constant
expression
minmax: simplify min()/max()/clamp() implementation
minmax: improve macro expansion and type checking
minmax: fix up min3() and max3() too
Matthew Wilcox (Oracle) (1):
minmax: add in_range() macro
