Subject[PATCH v3 0/6] Implement inline static calls on PPC32 - v3
Date
This series applies on top of the series v2 "objtool: Enable and
implement --mcount option on powerpc" [1]

A few modifications are done to core parts to enable powerpc
implementation:
- R_X86_64_PC32 is abstracted to R_REL32 so that it can then be
redefined as R_PPC_REL32.
- A call to static_call_init() is added to start_kernel() to avoid
every architecture to have to call it
- Trampoline address is provided to arch_static_call_transform() even
when setting a site to fallback on a call to the trampoline when the
target is too far.

This version of the series includes a preliminary patch (patch 1) that
should be squashed into Sathvika's series.

Christophe Leroy (6):
Fixup for "objtool/powerpc: Add --mcount specific implementation"
objtool: Add architecture specific R_REL32 macro
init: Call static_call_init() from start_kernel()
static_call_inline: Provide trampoline address when updating sites
powerpc: Prepare arch_static_call_transform() for supporting inline
static calls
powerpc/static_call: Implement inline static calls
