Dear stable kernel maintainers, Please consider applying the following mbox file to linux-5.4.y. It contains 2 cherry-picks of `Fixes:` for a patch in 5.4. Ard reported linux-5.4.y with CONFIG_THUMB2_KERNEL=y was broken without these in https://lore.kernel.org/stable/CAMj1kXGLrVXZPAoxTtMueB9toeoktuKza-mRpd4vZ0SLN6bSSQ@mail.gmail.com/. The mbox contains: commit f77ac2e378be ("ARM: 9030/1: entry: omit FP emulation for UND exceptions taken in kernel mode") commit 3cce9d44321e ("ARM: 9044/1: vfp: use undef hook for VFP support detection") They first landed in v5.11-rc1. The first is a fixup for: commit eff8728fe698 ("vmlinux.lds.h: Add PGO and AutoFDO input sections") which exists in 5.4.90 as 87ea51c90280. The first has a conflict in arch/arm/vfp/vfphw.S due to missing commit 2cbd1cc3dcd3 ("ARM: 8991/1: use VFP assembler mnemonics if available")] in 5.4. 2cbd1cc3dcd3 causes breakage in ARCH=axm55xx_defconfig previously reported: https://lore.kernel.org/stable/be846d89-ab5a-f02a-c05e-1cd40acc5baa@roeck-us.net/ and will need to be reworked if we ever do backport it. -- Thanks, ~Nick Desaulniers
