The purpose of this serie is to:
- use BATs with STRICT_KERNEL_RWX on book3s (See patch 12 for details.)
- use LTLBs with STRICT_KERNEL_RWX on 8xx (See patch 14 for a few details.)
v2:
- Fix patch 2 (was patch 3 in v1) based on feedback from Jonathan.
- Added support for 8xx with LTLBs.
- Added systematic population of pagetables for Abatron BDI.
Christophe Leroy (15):
powerpc/mm/32: add base address to mmu_mapin_ram()
powerpc/mm/32s: rework mmu_mapin_ram()
powerpc/mm/32s: use generic mmu_mapin_ram() for all blocks.
powerpc/32: always populate page tables for Abatron BDI.
powerpc/wii: remove wii_mmu_mapin_mem2()
powerpc/mm/32s: use _PAGE_EXEC in setbat()
powerpc/mm/32s: add setibat() clearibat() and update_bats()
powerpc/32: add helper to write into segment registers
powerpc/mmu: add is_strict_kernel_rwx() helper
powerpc/kconfig: define PAGE_SHIFT inside Kconfig
powerpc/kconfig: define CONFIG_DATA_SHIFT and CONFIG_ETEXT_SHIFT
powerpc/mm/32s: Use BATs for STRICT_KERNEL_RWX
powerpc/kconfig: make _etext and data areas alignment configurable on
Book3s 32
powerpc/8xx: don't disable large TLBs with CONFIG_STRICT_KERNEL_RWX
powerpc/kconfig: make _etext and data areas alignment configurable on
8xx
