commit 6d0d95ecc04a70f8448d562ff0fbbae237f5c929
Author: Kazuhito Hagio <k-hagio-ab@nec.com>
Date: Thu Apr 21 08:58:29 2022 +0900
[PATCH] Avoid false-positive mem_section validation with vmlinux
Currently get_mem_section() validates if SYMBOL(mem_section) is the address
of the mem_section array first. But there was a report that the first
validation wrongly returned TRUE with -x vmlinux and SPARSEMEM_EXTREME
(4.15+) on s390x. This leads to crash failing statup with the following
seek error:
crash: seek error: kernel virtual address: 67fffc2800 type: "memory section root table"
Skip the first validation when satisfying the conditions.

Subject: [PATCH] [PATCH] sadump: fix failure of reading memory when 5-level
paging is enabled
makedumpfile fails as follows for memory dumps collected by sadump
when 5-level paging is enabled on the corresponding systems:
# makedumpfile -l -d 31 -x ./vmlinux ./dump.sadump dump.sadump-ld31
__vtop4_x86_64: Can't get a valid pgd.
...snip...
__vtop4_x86_64: Can't get a valid pgd.
calc_kaslr_offset: failed to calculate kaslr_offset and phys_base; default to 0
__vtop4_x86_64: Can't get a valid pgd.
readmem: Can't convert a virtual address(ffffffff82fce960) to physical address.
readmem: type_addr: 0, addr:ffffffff82fce960, size:1024
cpu_online_mask_init: Can't read cpu_online_mask memory.
makedumpfile Failed.
This is because 5-level paging support has not been done yet for
sadump; the work of the 5-level paging support was done by the commit
30a3214a7193e94c551c0cebda5918a72a35c589 (PATCH 4/4 arch/x86_64: Add
5-level paging support) but that was focused on the core part only.
Having said that, most of things has already been finished in the
commit. What needs to be newly added for sadump is just how to check
if 5-level paging is enabled for a given memory dump.
For that purpose, let's refer to CR4.LA57, bit 12 of CR4, representing
whether 5-level paging is enabled or not. We can do this because
memory dumps collected by sadump have SMRAM as note information and
they include CR4 together with the other control registers.
