Subject: [PATCH v3 00/14] arch,mm: cleanup Kconfig entries for ARCH_FORCE_MAX_ORDER

From: "Mike Rapoport (IBM)" <rppt@...nel.org>

Hi,

Several architectures have ARCH_FORCE_MAX_ORDER in their Kconfig and
they all have wrong and misleading prompt and help text for this option.

Besides, some define insane limits for possible values of
ARCH_FORCE_MAX_ORDER, some carefully define ranges only for a subset of
possible configurations, some make this option configurable by users for no
good reason.

This set updates the prompt and help text everywhere and does its best to
update actual definitions of ranges where applicable.

kbuild generated a bunch of false positives because it assigns -1 to
ARCH_FORCE_MAX_ORDER, hopefully this will be fixed soon.

v3:
* fix rebase fallouts (Zi Yan)

v2: https://lore.kernel.org/all/20230324052233.2654090-1-rppt@kernel.org
* arm64: show prompt for ARCH_FORCE_MAX_ORDER only if EXPERT (Catalin)
* Add Acked- and Reviewed-by tags (thanks Geert, Kirill and Max)

v1: https://lore.kernel.org/all/20230323092156.2545741-1-rppt@kernel.org
