The ultimate goal is to synchronize all longterm branches so that they include the full set of minmax.h changes. 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. Changes between v1 and v2: - v1 included 15 patches: https://lore.kernel.org/stable/20250922103241.16213-1-farbere@amazon.com/T/#t - First 3 were pushed to the stable-tree. - 4th cauded amd driver's build to fail. - This change fixes it. - Modified files: drivers/gpu/drm/amd/amdgpu/amdgpu.h drivers/gpu/drm/amd/pm/swsmu/smu11/sienna_cichlid_ppt.c drivers/gpu/drm/amd/pm/swsmu/smu13/smu_v13_0_0_ppt.c drivers/gpu/drm/amd/pm/swsmu/smu13/smu_v13_0_7_ppt.c David Laight (7): 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 Linus Torvalds (5): minmax: make generic MIN() and MAX() macros available everywhere 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 arch/um/drivers/mconsole_user.c | 2 + drivers/edac/skx_common.h | 1 - drivers/gpu/drm/amd/amdgpu/amdgpu.h | 2 + .../drm/amd/display/modules/hdcp/hdcp_ddc.c | 2 + .../drm/amd/pm/powerplay/hwmgr/ppevvmath.h | 14 +- .../amd/pm/swsmu/smu11/sienna_cichlid_ppt.c | 2 + .../drm/amd/pm/swsmu/smu13/smu_v13_0_0_ppt.c | 3 + .../drm/amd/pm/swsmu/smu13/smu_v13_0_7_ppt.c | 3 + drivers/gpu/drm/amd/pm/swsmu/smu_cmn.c | 2 +- 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/media/dvb-frontends/stv0367_priv.h | 3 + .../net/can/usb/etas_es58x/es58x_devlink.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/tree-checker.c | 2 +- include/linux/compiler.h | 9 + include/linux/minmax.h | 220 ++++++++++-------- kernel/trace/preemptirq_delay_test.c | 2 - lib/btree.c | 1 - lib/decompress_unlzma.c | 2 + lib/vsprintf.c | 2 +- mm/zsmalloc.c | 2 - tools/testing/selftests/mm/mremap_test.c | 2 + tools/testing/selftests/seccomp/seccomp_bpf.c | 2 + 30 files changed, 192 insertions(+), 136 deletions(-) -- 2.47.3
