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@xxxxxxxxxxxxxx/.

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@xxxxxxxxxxxx/
and will need to be reworked if we ever do backport it.
