[v1,0/6] Miscellaneous cleanups

Message

Christophe Leroy Feb. 22, 2022, 10:38 a.m. UTC

This series applies on top of my series "Allocate module text and data separately" v4.

It contains some cleanups to the module core.

First patch brings back signature.c out of kernel/module/ as this file
is not directly linked to modules. Ideally this change should be squashed
in first patch of Aaron's series.

Second patch moves Kconfig's module related stuff in a dedicated Kconfig.

Patches 3-6 do some cleanup around the settling of modules's layout page flags.

Christophe Leroy (6):
  module: Have kernel/module/ dedicated to CONFIG_MODULES
  module: Move module's Kconfig item in kernel/module/
  module: Make module_enable_x() independent of
    CONFIG_ARCH_HAS_STRICT_MODULE_RWX
  module: Move module_enable_x() and frob_text() in strict_rwx.c
  module: Rework layout alignment to avoid BUG_ON()s
  module: Rename debug_align() as strict_align()
