Hi again, This is version two of the series I previously posted here: https://lore.kernel.org/r/20210225125921.13147-1-will@xxxxxxxxxx The main change since v1 is that, rather than "fix" the FDT code to follow the documented behaviour for CMDLINE_EXTEND, I've opted to remove the thing entirely for arm64 while a less ambiguous and generic replacement is developed, probably based on either [1] or [2]. I've left the first-patch as-is so that it's easier to incorporate whatever ends up replacing CMDLINE_EXTEND in future. Cheers, Will [1] https://patchwork.ozlabs.org/project/linuxppc-dev/cover/cover.1554195798.git.christophe.leroy@xxxxxx/ [2] https://patchwork.ozlabs.org/project/linuxppc-dev/patch/20190319232448.45964-2-danielwa@xxxxxxxxx/ --->8 Cc: Max Uvarov <muvarov@xxxxxxxxx> Cc: Rob Herring <robh@xxxxxxxxxx> Cc: Ard Biesheuvel <ardb@xxxxxxxxxx> Cc: Marc Zyngier <maz@xxxxxxxxxx> Cc: Doug Anderson <dianders@xxxxxxxxxxxx> Cc: Tyler Hicks <tyhicks@xxxxxxxxxxxxxxxxxxx> Cc: Frank Rowand <frowand.list@xxxxxxxxx> Cc: Arnd Bergmann <arnd@xxxxxxxx> Cc: Palmer Dabbelt <palmer@xxxxxxxxxxx> Cc: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> Cc: Catalin Marinas <catalin.marinas@xxxxxxx> Cc: <kernel-team@xxxxxxxxxxx> Cc: <linux-arm-kernel@xxxxxxxxxxxxxxxxxxx> Cc: <devicetree@xxxxxxxxxxxxxxx> Will Deacon (2): arm64: cpufeatures: Fix handling of CONFIG_CMDLINE for idreg overrides arm64: Drop support for CMDLINE_EXTEND arch/arm64/Kconfig | 6 ----- arch/arm64/kernel/idreg-override.c | 43 ++++++++++++++++-------------- 2 files changed, 23 insertions(+), 26 deletions(-) -- 2.30.1.766.gb4fecdf3b7-goog
