Hi Linus, As expected, kernel builds started failing in less-common configurations. In this particular case the culprit is amdgpu driver when built for 32-bit ARM in allmodconfig configuration using tip-of-trunk GCC. Hi Alex, [picking your name from “git log drivers/gpu/drm/amd/amdgpu/amdgpu.h

I think this is a false positive. It is doing: #define shift 2 #define mask (1ul<<(shift)) #define REG_FIELD_MASK(a,b) (mask) #define REG_FIELD_SHIFT(a,b) (shift) #define REG_SET_FIELD(orig_val, reg, field, field_val) \ (((orig_val) & ~REG_FIELD_MASK(reg, field)) |

Ok, I am now able to reproduce it with: #define shiftCB_DISABLE_FAULT_ON_UNMAPPED_ACCESS1 0 #define maskCB_DISABLE_FAULT_ON_UNMAPPED_ACCESS1 1L #define REG_FIELD_MASK(a,b) (mask##b) #define REG_FIELD_SHIFT(a,b) (shift##b) #define REG_SET_FIELD(orig_val, reg, field, field_val) \

Oh it is only on the trunk of GCC so to some extend it caught a regression in GCC :). From: linaro-toolchain on behalf of Andrew Pinski Sent: Wednesday, September 8, 2021 2:36 PM To: Maxim Kuvyrkov; Linus Torvalds; Alex Deucher Cc: linaro-toolchain Subj
