Subject: [PATCH v1 00/13] powerpc/32s: Use BATs for STRICT_KERNEL_RWX
Date: Thu, 29 Nov 2018 19:00:10 +0000 (UTC) [thread overview]
Message-ID: <cover.1543517818.git.christophe.leroy@c-s.fr> (raw)
The purpose of this serie is to use BATs with STRICT_KERNEL_RWX
See patch 12 for details.
Christophe Leroy (13):
powerpc/mm: add exec protection on powerpc 603
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/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
