Re: [PATCH v6 00/14] crash: Fix several bugs

Hi Jinjie,

Sorry for the delay, it's been really busy time for me.

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.

It feels like these are three independent series, maybe with slight
dependencies because they touch related code, but it's not really a
single series:

Jinjie Ruan (14):
  kexec: Fix CMA segment address translation with non-zero text_offset
  kexec: Record allocated CMA pages to fix release size mismatch
  kexec: Extract kexec_free_segment_cma() from kimage_free_cma()
  arm64: kexec_file: Fix CMA page leaks in segment placement retry loops
  arm64: kexec_file: Fix elf_headers memory leak in retry loop
  LoongArch: kexec_file: Fix CMA page leaks in segment placement retry
    loops
  LoongArch: kexec_file: Fix elf_headers memory leak in retry loop

The very similar commits for arm64 and LoongArch imply that that we have
some code duplication that should be addressed regardless of these
fixes.
