As Baoquan and Catalin suggested, this patch set fixes
several pre-existing code issues found by Sashiko AI [1][2][3].

The major improvements and fixes included in this series are:
- Fix several memory leaks for arm64, and similar issues on LoongArch.
- Fix out-of-bounds write on 32-bit Highmem for x86.
- Fix TOCTOU race in crash memory range collection.

Hi all,

Gentle ping.

Could anyone take a look or let me know if there's anything
else needed? I can rebase/resend if required.

Sorry for the delay, I was travelling for the past few weeks.
I'm planning to review this next week. 

And we do need acks from arch maintainers for most of the patches in this
series.
