The ultimate goal is to synchronize all longterm branches so that they include the full set of minmax.h changes. Previous work to update 6.12.48: https://lore.kernel.org/stable/20250922103123.14538-1-farbere@amazon.com/T/#t and 6.6.107: https://lore.kernel.org/stable/20250922103241.16213-1-farbere@amazon.com/T/#t 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 older kernels. 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. 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: simplify and clarify min_t()/max_t() implementation minmax: make generic MIN() and MAX() macros available everywhere minmax: add a few more MIN_T/MAX_T users minmax: simplify min()/max()/clamp() implementation minmax: don't use max() in situations that want a C constant expression 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 +- drivers/gpu/drm/amd/pm/swsmu/smu_cmn.c | 2 +- .../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/irqchip/irq-sun6i-r.c | 2 +- drivers/md/dm-integrity.c | 2 +- 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 - drivers/virt/acrn/ioreq.c | 4 +- fs/btrfs/misc.h | 2 - fs/btrfs/tree-checker.c | 2 +- fs/ext2/balloc.c | 2 - fs/ext4/ext4.h | 2 - fs/ufs/util.h | 6 - include/linux/compiler.h | 9 + include/linux/minmax.h | 264 +++++++++++++----- include/linux/pageblock-flags.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 +- 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 +- .../selftests/bpf/progs/get_branch_snapshot.c | 4 +- tools/testing/selftests/seccomp/seccomp_bpf.c | 2 + tools/testing/selftests/vm/mremap_test.c | 2 + 48 files changed, 290 insertions(+), 184 deletions(-) -- 2.47.3
