The goal is to have text be RO/NX and everything else be RW/NX. I finally got my hands on a Juno board so I was able to do more testing with both 4K and 64K pages although I still haven't tested with EFI. This is based off of 3.18-rc5. Thanks, Laura Laura Abbott (7): arm64: Treat handle_arch_irq as a function pointer arm64: Switch to adrp for loading the stub vectors arm64: Move cpu_resume into the text section arm64: Move some head.text functions to executable section arm64: Factor out fixmap initialiation from ioremap arm64: use fixmap for text patching when text is RO arm64: add better page protections to arm64 arch/arm64/Kconfig.debug | 23 ++ arch/arm64/include/asm/cacheflush.h | 4 + arch/arm64/include/asm/fixmap.h | 8 +- arch/arm64/include/asm/insn.h | 2 + arch/arm64/include/asm/irq.h | 1 - arch/arm64/kernel/entry.S | 6 +- arch/arm64/kernel/head.S | 409 +++++++++++++++++----------------- arch/arm64/kernel/insn.c | 72 +++++- arch/arm64/kernel/irq.c | 2 + arch/arm64/kernel/jump_label.c | 2 +- arch/arm64/kernel/setup.c | 1 + arch/arm64/kernel/sleep.S | 29 +-- arch/arm64/kernel/suspend.c | 4 +- arch/arm64/kernel/vmlinux.lds.S | 21 ++ arch/arm64/mm/init.c | 1 + arch/arm64/mm/ioremap.c | 93 +------- arch/arm64/mm/mm.h | 2 + arch/arm64/mm/mmu.c | 429 ++++++++++++++++++++++++++++++++---- 18 files changed, 743 insertions(+), 366 deletions(-) -- Qualcomm Innovation Center, Inc.
