Hi, This is v4 of the series to add CONFIG_DEBUG_VIRTUAL for arm64. This mostly expanded on __pa_symbol conversion with a few new sites found. There's also some reworking done to avoid calling __va too early. __va relies on having memstart_addr set so very early code in early_fixmap_init and early KASAN initialization can't just call __va(__Ipa_symbol(...)) to get the linear map alias. I found this while testing with DEBUG_VM. All of this could use probably use more testing under more configurations. KVM, Xen, kexec, hibernate should all be tested. Thanks, Laura Laura Abbott (10): lib/Kconfig.debug: Add ARCH_HAS_DEBUG_VIRTUAL mm/cma: Cleanup highmem check arm64: Move some macros under #ifndef __ASSEMBLY__ arm64: Add cast for virt_to_pfn arm64: Use __pa_symbol for kernel symbols xen: Switch to using __pa_symbol kexec: Switch to __pa_symbol mm/kasan: Switch to using __pa_symbol and lm_alias mm/usercopy: Switch to using lm_alias arm64: Add support for CONFIG_DEBUG_VIRTUAL arch/arm64/Kconfig | 1 + arch/arm64/include/asm/kvm_mmu.h | 4 +- arch/arm64/include/asm/memory.h | 67 ++++++++++++++++++++++--------- arch/arm64/include/asm/mmu_context.h | 6 +-- arch/arm64/include/asm/pgtable.h | 2 +- arch/arm64/kernel/acpi_parking_protocol.c | 2 +- arch/arm64/kernel/cpu-reset.h | 2 +- arch/arm64/kernel/cpufeature.c | 2 +- arch/arm64/kernel/hibernate.c | 13 +++--- arch/arm64/kernel/insn.c | 2 +- arch/arm64/kernel/psci.c | 2 +- arch/arm64/kernel/setup.c | 8 ++-- arch/arm64/kernel/smp_spin_table.c | 2 +- arch/arm64/kernel/vdso.c | 4 +- arch/arm64/mm/Makefile | 2 + arch/arm64/mm/init.c | 11 ++--- arch/arm64/mm/kasan_init.c | 21 ++++++---- arch/arm64/mm/mmu.c | 32 +++++++++------ arch/arm64/mm/physaddr.c | 28 +++++++++++++ arch/x86/Kconfig | 1 + drivers/firmware/psci.c | 2 +- drivers/xen/xenbus/xenbus_dev_backend.c | 2 +- drivers/xen/xenfs/xenstored.c | 2 +- include/linux/mm.h | 4 ++ kernel/kexec_core.c | 2 +- lib/Kconfig.debug | 5 ++- mm/cma.c | 15 +++---- mm/kasan/kasan_init.c | 12 +++--- mm/usercopy.c | 4 +- 29 files changed, 167 insertions(+), 93 deletions(-) create mode 100644 arch/arm64/mm/physaddr.c -- 2.7.4
