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? http://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=291129 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
