This patch adds powerpc specific functions required for
'objtool mcount' to work, and enables mcount for ppc.
I would love to see more objtool enablement for Power :-)
I have not received this series and I can't see it on powerpc patchwork
either (https://patchwork.ozlabs.org/project/linuxppc-dev/list/)
Did you send it to linuxppc-dev list ? If not can you resend it there ?
It is there, might have been delayed?

There are some CI failures.
On PPC32 I get :
[ 0.000000] ftrace: No functions to be traced?
Without this series I get:
[ 0.000000] ftrace: allocating 22508 entries in 17 pages
[ 0.000000] ftrace: allocated 17 pages with 2 groups
ppc64_defconfig on QEMU:
[ 0.000000][ T0] ftrace: No functions to be traced?
Without your series:
[ 0.000000][ T0] ftrace: allocating 38750 entries in 15 pages
[ 0.000000][ T0] ftrace: allocated 15 pages with 4 groups
[ 0.000000][ T0] trace event string verifier disabled
ppc64le_defconfig on QEMU:
[ 0.000000][ T0] ftrace: allocating 37236 entries in 14 pages
[ 0.000000][ T0] ftrace: allocated 14 pages with 3 groups
Without your series:
[ 0.000000][ T0] ftrace: allocating 37236 entries in 14 pages
[ 0.000000][ T0] ftrace: allocated 14 pages with 3 groups
So it seems it works only on Little Endian.
Works neither on PPC32 nor on PPC64 Big Endian
