With previous patch adding HAVE_FUNCTION_GRAPH_FREGS for powerpc, FPROBE can be enabled on powerpc. But with the commit b5fa903b7f7c ("fprobe: Add fprobe_header encoding feature"), asm/fprobe.h header is needed to define arch dependent encode/decode macros. The fprobe header MSB pattern on powerpc is not 0xf. So, define FPROBE_HEADER_MSB_PATTERN expected on powerpc. Also, commit 762abbc0d09f ("fprobe: Use ftrace_regs in fprobe exit handler") introduced HAVE_FTRACE_REGS_HAVING_PT_REGS for archs that have pt_regs in ftrace_regs. Advertise that on powerpc to reuse common definitions like ftrace_partial_regs().
