I had an older patch that I revived to have this defined through Kconfig rather than through including asm/page.h, which is not allowed in vdso code. The vdso patch series now has a temporary workaround, but I still want to get this into v6.9 so we can place the hack with CONFIG_PAGE_SIZE in the vdso. I've applied this to the asm-generic tree already, please let me know if there are still remaining issues. It's really close to the merge window already, so I'd probably give this a few more days before I send a pull request, or defer it to v6.10 if anything goes wrong. Sorry for the delay, I was still waiting to resolve the m68k question, but there were no further replies in the end, so I kept my original version. Changes from v1: - improve Kconfig help texts - remove an extraneous line in hexagon Arnd Link: https://lore.kernel.org/lkml/CA+G9fYtrXXm_KO9fNPz3XaRxHV7UD_yQp-TEuPQrNRHU+_0W_Q@mail.gmail.com/ Link: https://lore.kernel.org/all/65dc6c14.170a0220.f4a3f.91dd@mx.google.com/ Link: https://lore.kernel.org/lkml/20240226161414.2316610-1-arnd@kernel.org/ Arnd Bergmann (3): arch: consolidate existing CONFIG_PAGE_SIZE_*KB definitions arch: simplify architecture specific page size configuration arch: define CONFIG_PAGE_SIZE_*KB on all architectures arch/Kconfig | 92 +++++++++++++++++++++++++++++- arch/alpha/Kconfig | 1 + arch/alpha/include/asm/page.h | 2 +- arch/arc/Kconfig | 3 + arch/arc/include/uapi/asm/page.h | 6 +- arch/arm/Kconfig | 1 + arch/arm/include/asm/page.h | 2 +- arch/arm64/Kconfig | 29 +++++----- arch/arm64/include/asm/page-def.h | 2 +- arch/csky/Kconfig | 1 + arch/csky/include/asm/page.h | 2 +- arch/hexagon/Kconfig | 24 ++------ arch/hexagon/include/asm/page.h | 6 +- arch/loongarch/Kconfig | 21 ++----- arch/loongarch/include/asm/page.h | 10 +--- arch/m68k/Kconfig | 3 + arch/m68k/Kconfig.cpu | 2 + arch/m68k/include/asm/page.h | 6 +- arch/microblaze/Kconfig | 1 + arch/microblaze/include/asm/page.h | 2 +- arch/mips/Kconfig | 58 ++----------------- arch/mips/include/asm/page.h | 16 +----- arch/nios2/Kconfig | 1 + arch/nios2/include/asm/page.h | 2 +- arch/openrisc/Kconfig | 1 + arch/openrisc/include/asm/page.h | 2 +- arch/parisc/Kconfig | 3 + arch/parisc/include/asm/page.h | 10 +--- arch/powerpc/Kconfig | 31 ++-------- arch/powerpc/include/asm/page.h | 2 +- arch/riscv/Kconfig | 1 + arch/riscv/include/asm/page.h | 2 +- arch/s390/Kconfig | 1 + arch/s390/include/asm/page.h | 2 +- arch/sh/include/asm/page.h | 13 +---- arch/sh/mm/Kconfig | 42 ++++---------- arch/sparc/Kconfig | 2 + arch/sparc/include/asm/page_32.h | 2 +- arch/sparc/include/asm/page_64.h | 3 +- arch/um/Kconfig | 1 + arch/um/include/asm/page.h | 2 +- arch/x86/Kconfig | 1 + arch/x86/include/asm/page_types.h | 2 +- arch/xtensa/Kconfig | 1 + arch/xtensa/include/asm/page.h | 2 +- scripts/gdb/linux/constants.py.in | 2 +- scripts/gdb/linux/mm.py | 2 +- 47 files changed, 185 insertions(+), 238 deletions(-) Reviewed-by: Vincenzo Frascino
