Message

Jinjie Ruan July 19, 2024, 9:57 a.m. UTC

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 v4:
- Add the missing macro for loongarch.
- Only define the macro for 64bit RISCV.
- Signed-off-by -> Suggested-by as suggested.
- Remove the Tested-by as suggested.
- Update the commit message.
- Add acked-by.

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.
