The ultimate goal is to synchronize all long-term branches so that they include the full set of minmax.h changes. - 6.12.y has already been backported; the changes are included in v6.12.49. - 6.6.y has already been backported; the changes are included in v6.6.109. - 6.1.y has already been backported; the changes are currently in the 6.1-stable tree. - 5.15.y has already been backported; the changes are currently in the 5.15-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. The first two patches in this series were added to prevent build failures caused by changes introduced later in minmax.h. - Commit 92d23c6e9415 ("overflow, tracing: Define the is_signed_type() macro once") is needed for commit 75ca38c1960f ("minmax: allow min()/max()/clamp()"). - Commit cea628008fc8 ("btrfs: remove duplicated in_range() macro") is needed for commit f9bff0e31881 ("minmax: add in_range() macro"). The changes were tested using `make allyesconfig` and `make allmodconfig` for arm64, arm, x86_64 and i386 architectures. Changes in v2: The series was updated after initially backporting and approving the newer long-term branches. 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 Herve Codina (1): minmax: Introduce {min,max}_array() Jason A. Donenfeld (2): minmax: sanity check constant bounds when clamping minmax: clamp more efficiently by avoiding extra comparison Johannes Thumshirn (1): btrfs: remove duplicated in_range() macro 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 arch/arm/mm/pageattr.c | 6 +- arch/um/drivers/mconsole_user.c | 2 + arch/x86/mm/pgtable.c | 2 +- drivers/edac/sb_edac.c | 4 +- drivers/edac/skx_common.h | 1 - .../drm/amd/display/modules/hdcp/hdcp_ddc.c | 2 + .../drm/amd/pm/powerplay/hwmgr/ppevvmath.h | 14 +- .../drm/arm/display/include/malidp_utils.h | 2 +- .../display/komeda/komeda_pipeline_state.c | 24 +- drivers/gpu/drm/drm_color_mgmt.c | 2 +- drivers/gpu/drm/msm/adreno/a6xx_gmu.c | 6 - drivers/gpu/drm/radeon/evergreen_cs.c | 2 + drivers/hwmon/adt7475.c | 24 +- drivers/input/touchscreen/cyttsp4_core.c | 2 +- drivers/md/dm-integrity.c | 6 +- drivers/media/dvb-frontends/stv0367_priv.h | 3 + .../net/ethernet/chelsio/cxgb3/cxgb3_main.c | 18 +- .../net/ethernet/stmicro/stmmac/stmmac_main.c | 2 +- drivers/net/fjes/fjes_main.c | 4 +- drivers/nfc/pn544/i2c.c | 2 - drivers/platform/x86/sony-laptop.c | 1 - drivers/scsi/isci/init.c | 6 +- .../pci/hive_isp_css_include/math_support.h | 5 - fs/btrfs/ctree.h | 2 - fs/btrfs/extent_io.c | 1 + fs/btrfs/file-item.c | 1 + fs/btrfs/misc.h | 2 - fs/btrfs/raid56.c | 1 + fs/btrfs/tree-checker.c | 2 +- fs/erofs/zdata.h | 2 +- fs/ext2/balloc.c | 2 - fs/ext4/ext4.h | 2 - fs/ufs/util.h | 6 - include/linux/compiler.h | 15 + include/linux/minmax.h | 267 ++++++++++++++---- include/linux/overflow.h | 1 - include/linux/trace_events.h | 2 - kernel/trace/preemptirq_delay_test.c | 2 - lib/btree.c | 1 - lib/decompress_unlzma.c | 2 + lib/logic_pio.c | 3 - lib/vsprintf.c | 2 +- lib/zstd/zstd_internal.h | 2 - mm/zsmalloc.c | 1 - net/ipv4/proc.c | 2 +- net/ipv6/proc.c | 2 +- net/netfilter/nf_nat_core.c | 6 +- net/tipc/core.h | 2 +- net/tipc/link.c | 10 +- 49 files changed, 312 insertions(+), 169 deletions(-) -- 2.47.3
