There have been reports of failed boots with Xen due to an overlap of the kernel's memory with ACPI NVS reported in the E820 map of the host. This series fixes this issue by moving the NVS area in dom0 to some higher address. Changes in V2: - split of v1 patch 5 - new patch 6 Juergen Gross (7): xen: use correct end address of kernel for conflict checking xen: introduce generic helper checking for memory map conflicts xen: move checks for e820 conflicts further up xen: move max_pfn in xen_memory_setup() out of function scope xen: add capability to remap non-RAM pages to different PFNs xen: allow mapping ACPI data using a different physical address xen: tolerate ACPI NVS memory overlapping with Xen allocated memory arch/x86/include/asm/acpi.h | 8 ++ arch/x86/kernel/acpi/boot.c | 10 ++ arch/x86/kernel/mmconf-fam10h_64.c | 2 +- arch/x86/kernel/x86_init.c | 2 +- arch/x86/xen/mmu_pv.c | 5 +- arch/x86/xen/p2m.c | 95 ++++++++++++++ arch/x86/xen/setup.c | 203 ++++++++++++++++++++++------- arch/x86/xen/xen-ops.h | 6 +- 8 files changed, 279 insertions(+), 52 deletions(-) -- 2.43.0
