Subject: [PATCH v3 0/3] crash: Fix x86_32 memory reserve dead loop bug

Fix two bugs for x86_32 crash memory reserve, and prepare to apply generic
crashkernel reservation to 32bit system. Then use generic interface to
simplify crashkernel reservation for ARM32.

changes in v3:
- Fix it as Baoquan suggested.
- Update the commit message.

changes in v2:
- Peel off the other two patches.
- Update the commit message and fix tag.
