Hi all, This patch series contains clean-up for the ARM memory subsystem in preparation of reworking the page tables handling. A branch with the patches can be found on xenbits: https://xenbits.xen.org/git-http/people/julieng/xen-unstable.git branch mm-cleanup-v2 For all the changes see in each patch. Cheers, Julien Grall (24): xen/x86: mm: Introduce {G,M}FN <-> {G,M}ADDR helpers xen/mm: Use typesafe MFN for alloc_boot_pages return xen/mm: Use __virt_to_mfn in map_domain_page instead of virt_to_mfn xen/arm: mm: Redefine mfn_to_virt to use typesafe xen/arm: hsr_iabt: Document RES0 field xen/arm: traps: Don't define FAR_EL2 for ARM32 xen/arm: arm32: Don't define FAR_EL1 xen/arm: Add FnV field in hsr_*abt xen/arm: Introduce hsr_xabt to gather common bits between hsr_dabt and xen/arm: traps: Introduce a helper to read the hypersivor fault register xen/arm: traps: Improve logging for data/prefetch abort fault xen/arm: Replace ioremap_attr(PAGE_HYPERVISOR_NOCACHE) call by ioremap_nocache xen/arm: page: Remove unused attributes DEV_NONSHARED and DEV_CACHED xen/arm: page: Use directly BUFFERABLE and drop DEV_WC xen/arm: page: Prefix memory types with MT_ xen/arm: page: Use ARMv8 naming to improve readability xen/arm: page: Clean-up the definition of MAIRVAL xen/arm: mm: Rename and clarify AP[1] in the stage-1 page table xen/arm: Switch to SYS_STATE_boot just after end_boot_allocator() xen/arm: mm: Rename 'ai' into 'flags' in create_xen_entries xen/arm: page: Describe the layout of flags used to update page tables xen/arm: mm: Embed permission in the flags xen/arm: mm: Handle permission flags when adding a new mapping xen/arm: mm: Use memory flags for modify_xen_mappings rather than custom one xen/arch/arm/kernel.c | 2 +- xen/arch/arm/livepatch.c | 6 +-- xen/arch/arm/mm.c | 74 +++++++++++++++-------------- xen/arch/arm/platforms/exynos5.c | 2 +- xen/arch/arm/platforms/omap5.c | 6 +-- xen/arch/arm/platforms/vexpress.c | 2 +- xen/arch/arm/setup.c | 12 +++-- xen/arch/arm/traps.c | 52 +++++++++++++++++--- xen/arch/x86/mm.c | 7 +-- xen/arch/x86/numa.c | 2 +- xen/arch/x86/srat.c | 5 +- xen/common/page_alloc.c | 7 ++- xen/drivers/acpi/osl.c | 2 +- xen/drivers/video/arm_hdlcd.c | 2 +- xen/include/asm-arm/cpregs.h | 2 - xen/include/asm-arm/lpae.h | 2 +- xen/include/asm-arm/mm.h | 3 +- xen/include/asm-arm/page.h | 99 ++++++++++++++++++++++----------------- xen/include/asm-arm/processor.h | 25 ++++++++-- xen/include/asm-x86/page.h | 4 ++ xen/include/xen/domain_page.h | 2 +- xen/include/xen/mm.h | 3 +- 22 files changed, 200 insertions(+), 121 deletions(-)
