From: Youling Tang
Date: Wed Apr 21 2021 - 22:25:09 EST


1. Fix the "mem=" parameter parsing problem.
2. Solve the problem that panic may be triggered due to insufficient memory
when entering the capture kernel.
3. Fix the problem that the captured production kernel data may be destroyed.

Youling Tang (4):
MIPS: Fix cmdline "mem=" parameter parsing
mips: kdump: Capture kernel should be able to see old memories
mips: kdump: Reserve extra memory for crash dump
mips: kdump: Reserve old memory to avoid the destruction of production
kernel data
