| Subject: MIPS: kexec: Relax memory restriction |
| |
| From: Dengcheng Zhu <dzhu@wavecomp.com> |
| |
| [ Upstream commit a6da4d6fdf8bd512c98d3ac7f1d16bc4bb282919 ] |
| |
| We can rely on the system kernel and the dump capture kernel themselves in |
| memory usage. |
| |
| Being restrictive with 512MB limit may cause kexec tool failure on some |
| platforms. |
