The goal is to have text be RO/NX and everything else be RW/NX. The biggest change here is the addition of ioremap_exec for EFI services. The series did its job and caught EFI services trying to use regular RAM for code purposes. Laura Abbott (8): 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: efi: Use ioremap_exec for code sections arm64: add better page protections to arm64 arch/arm64/Kconfig.debug | 23 ++ arch/arm64/include/asm/cacheflush.h | 7 + arch/arm64/include/asm/fixmap.h | 8 +- arch/arm64/include/asm/insn.h | 2 + arch/arm64/include/asm/io.h | 1 + arch/arm64/include/asm/irq.h | 1 - arch/arm64/include/asm/pgtable.h | 1 + arch/arm64/kernel/efi.c | 12 +- arch/arm64/kernel/entry.S | 6 +- arch/arm64/kernel/head.S | 410 +++++++++++++++++++----------------- 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 | 36 +--- arch/arm64/kernel/suspend.c | 4 +- arch/arm64/kernel/vmlinux.lds.S | 18 +- arch/arm64/mm/init.c | 1 + arch/arm64/mm/ioremap.c | 99 ++------- arch/arm64/mm/mm.h | 2 + arch/arm64/mm/mmu.c | 405 +++++++++++++++++++++++++++++++---- 21 files changed, 740 insertions(+), 373 deletions(-) -- Qualcomm Innovation Center, Inc.
