Subject: [PATCHv4 0/4] arm64: make phys_to_virt() correct
Date: Tue, 18 Jan 2022 15:48:08 +0800 [thread overview]
Message-ID: <20220118074812.27702-1-piliu@redhat.com> (raw)
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.
v3 -> v4:
address the date type in [1/4] and [2/4]
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
