Yes, that's the one. The kbuild maintainer modified the commit message to add a maintainer Signed-off-by line.

I would say that any kernel versions that are shipped for actively maintained versions of Ubuntu that support hardware platforms that don't use the C version of recordmcount:

for file in arch/*/Kconfig; do if ! grep '^[[:space:]]*select HAVE_C_RECORDMCOUNT $file > /dev/null; then echo $file | cut -f2 -d/; fi; done
alpha
arc
c6x
h8300
hexagon
ia64
m68k
microblaze
nds32
nios2
openrisc
parisc
powerpc
riscv
s390
sh
um
unicore32
xtensa

This particular problem was observed on powerpc, specifically, ppc64le. Of course, it's up to the Canonical kernel maintainers to decide which kernels could best benefit from a backport; I just wanted to bring the issue and fix to Canonical's attention.
