[PATCH 0/3] kfence: fix pool allocation failure handling

[Jackie Liu]

From: Jackie Liu <liuyun01 at kylinos.cn>

Fix the cleanup address and page reuse window in failed late KFENCE
initialization. Also let RISC-V boot if the early pool reservation fails.

Patch 2 depends on patch 1. Patch 3 can be applied independently.

Validation: source review, git diff --check, and checkpatch.pl --strict.
OpenAI Codex assisted with review, adaptation, and commit wording.

Jackie Liu (3):
  kfence: fix pool cleanup on metadata allocation failure
  kfence: clear the pool pointer before freeing pages
  riscv: keep booting if KFENCE pool reservation fails
