Hi tao
crash load 5.12 before vmcore, parse section_size_bits equals 27,
but it should be equals 30. because defined "CONFIG_ARM64_4K_PAGES",
The commit "568c6f04" for compat android gki, so we should cleanup.

Hi Guanyou & lianbo,
I re-thought about the patch, and I agree the revert patch should be
applied, the reverted code is already covered by the previous:
if (THIS_KERNEL_VERSION >= LINUX(5,12,0)) {
...
else
...
hunk, so there is no need for the
CONFIG_ARM64_4K_PAGES/CONFIG_ARM64_16K_PAGES checks here. Previously
the patch was applied for the compatibility of android kernel due to
its customization, mainline kernel won't need this.
What do you think? @Lianbo Jiang
Thanks,
Tao Liu

Sorry for the late reply, Tao and Guanyou.
I agree with you, let's revert this one(because that patch seems not
needed.)
