Currently phys_to_virt() does not work well on 52-bits VA arm64 kernel. One issue is contributed by phys_offset not signed. The other is contributed by wrong page_offset. v2 -> v3: Discussed with Kairui off-list, 48-bits VA kernel can not handle flipped mm yet. So introducing [4/4], which judges whether the kernel is with flipped mm layout and adopt different formula accordingly. As for [1-3/4], they are the same as [1-3/3] in V2. v1 -> v2 Fix broken patch [2/3] in v1 Move arch_scan_vmcoreinfo declaration to util_lib/include/elf_info.h Using UINT64_MAX instread of 0xffffffffffffffff Cc: Kairui Song <kasong@xxxxxxxxxxx> Cc: Simon Horman <horms@xxxxxxxxxxxx> Cc: Philipp Rudo <prudo@xxxxxxxxxx> To: kexec@xxxxxxxxxxxxxxxxxxx *** BLURB HERE *** Kairui Song (1): arm64: fix PAGE_OFFSET calc for flipped mm Pingfan Liu (3): arm64: make phys_offset signed arm64/crashdump: unify routine to get page_offset arm64: read VA_BITS from kcore for 52-bits VA kernel kexec/arch/arm64/crashdump-arm64.c | 23 +----------- kexec/arch/arm64/kexec-arm64.c | 60 ++++++++++++++++++++++++------ kexec/arch/arm64/kexec-arm64.h | 3 +- util_lib/elf_info.c | 7 +++- util_lib/include/elf_info.h | 3 +- 5 files changed, 60 insertions(+), 36 deletions(-) -- 2.31.1 _______________________________________________ kexec mailing list kexec@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/kexec
