[PATCH v3 0/4] Miscellaneous cleanups

This series applies on top of my series "Allocate module text and data separately" v5.

It does some cleanup around the settling of modules's layout page flags:
- Make module_enable_x() independent of CONFIG_ARCH_HAS_STRICT_MODULE_RWX
- Reunify everything into strict_rwx.c
- Change big hammer BUG_ON()s into WARN_ON()s
- Change misleading debug_align() to strict_align()

Changes in v2/v3:
- Rebased on top of my series "Allocate module text and data separately" v5
- Moved the Kconfig patch out of this series, it is an independent change

Sorry for the mess in v2.

Christophe Leroy (4):
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()
