Subject: [PATCH v2 0/5] powerpc/64: avoid GOT addressing, don't put data in TOC
Date: Mon, 26 Sep 2022 13:40:52 +1000 [thread overview]
Message-ID: <20220926034057.2360083-1-npiggin@gmail.com> (raw)
This is a cleaned up set of the initial prep patches from the pcrel
series, dealing with regularising addressing variables from asm
and using helper macros more consistently.
Changes since v1:
- Use "REGS" stack frame marker for 64-bit, leaving 32-bit unchanged.
- Fix PPC64 32-bit boot wrapper compile.
Nicholas Piggin (5):
powerpc/64: use 32-bit immediate for STACK_FRAME_REGS_MARKER
powerpc/64: asm use consistent global variable declaration and access
powerpc/64: switch asm helpers from GOT to TOC relative addressing
powerpc/64: provide a helper macro to load r2 with the kernel TOC
powerpc/64e: provide an addressing macro for use with TOC in alternate
register
