Hi all,
After merging the arm tree, today's linux-next build (arm multi_v7_defconfig) failed like this:
In file included from <command-line>: arch/arm/mm/mmu.c: In function 'early_fixmap_init': include/linux/compiler_types.h:328:38: error: call to '__compiletime_assert_295' declared with attribute error: BUILD_BUG_ON failed: (__fix_to_virt(__end_of_fixmap_region) >> PMD_SHIFT) != FIXADDR_TOP >> PMD_SHIFT 328 | _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__) | ^ include/linux/compiler_types.h:309:4: note: in definition of macro '__compiletime_assert' 309 | prefix ## suffix(); \ | ^~~~~~ include/linux/compiler_types.h:328:2: note: in expansion of macro '_compiletime_assert' 328 | _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__) | ^~~~~~~~~~~~~~~~~~~ include/linux/build_bug.h:39:37: note: in expansion of macro 'compiletime_assert' 39 | #define BUILD_BUG_ON_MSG(cond, msg) compiletime_assert(!(cond), msg) | ^~~~~~~~~~~~~~~~~~ include/linux/build_bug.h:50:2: note: in expansion of macro 'BUILD_BUG_ON_MSG' 50 | BUILD_BUG_ON_MSG(condition, "BUILD_BUG_ON failed: " #condition) | ^~~~~~~~~~~~~~~~ arch/arm/mm/mmu.c:372:2: note: in expansion of macro 'BUILD_BUG_ON' 372 | BUILD_BUG_ON((__fix_to_virt(__end_of_fixmap_region) >> PMD_SHIFT) | ^~~~~~~~~~~~
Exposed by commit
9b89a073e1ca ("ARM: 9149/1: add BUILD_BUG_ON to check if fixmap range spans multiple pmds")
I have no idea why that BUILD_BUG_ON hits, so I have just reverted that commit for today.
