[PATCH] kexec: avoid out of bounds in crash_exclude_mem_range()

[Yuntao Wang]

Hi fuqiang,

Yesterday, I posted two patches that happen to address the bugs you an Baoquan
are currently discussing here, I wasn't aware that you both were also working
on fixing these issues.

Baoquan suggested I talk to you about it.

If you're interested, you can take a look at my patches and review them to see
if there are any issues. If everything is fine, and if you're willing, you can
also add a 'Reviewed-by' tag there.

The following link is for the two patches I posted yesterday:

Sincerely,
