This is the start of the stable review cycle for the 6.1.79 release. There are 197 patches in this series, all will be posted as a response to this one. If anyone has any issues with these being applied, please let me know.

The whole patch series can be found in one patch at: https://www.kernel.org/pub/linux/kernel/v6.x/stable-review/patch-6.1.79-rc1.... or in the git tree and branch at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git linux-6.1.y and the diffstat can be found below.

We see a regression with PowerPC:
-----8<----- /builds/linux/arch/powerpc/kernel/cpu_setup_6xx.S: Assembler messages: /builds/linux/arch/powerpc/kernel/cpu_setup_6xx.S:124: Error: unrecognized opcode: `sym_func_start_local(setup_g2_le_hid2)' /builds/linux/arch/powerpc/kernel/cpu_setup_6xx.S:131: Error: unrecognized opcode: `sym_func_end(setup_g2_le_hid2)' make[4]: *** [/builds/linux/scripts/Makefile.build:382: arch/powerpc/kernel/cpu_setup_6xx.o] Error 1 ----->8-----
This is seen only on PowerPC with GCC 8, GCC 13, Clang 17, Clang nightly, on:
- allnoconfig
- tinyconfig
- mpc83xx_defconfig
- ppc6xx_defconfig
(at least)
Reproducer:
tuxmake \ --runtime podman \ --target-arch powerpc \ --toolchain gcc-8 \ --kconfig tinyconfig
Bisection points to:
commit a65d7a833f486d0c162fdc854d2d5dd2e66ddd95 Author: Matthias Schiffer matthias.schiffer@ew.tq-group.com Date: Wed Jan 24 11:38:38 2024 +0100
powerpc/6xx: set High BAT Enable flag on G2_LE cores [ Upstream commit a038a3ff8c6582404834852c043dadc73a5b68b4 ]Reverting that commit makes the build pass again.
It seems that backporting the mentioned commit verbatim would also require 2da37761671b5bdedbe04e6469cfa57cd6b6ae45 ("powerpc/32: Fix objtool unannotated intra-function call warnings") to make SYM_FUNC_START_LOCAL/SYM_FUNC_END available. Please drop this patch from 6.1 and older for now.
Adding Christophe and Michael to cc. Is backporting the additional patch an option (and if so, for which kernel versions?), or should I send a new patch that does not use SYM_FUNC_START_LOCAL/SYM_FUNC_END for stable?
Thanks, Matthias
