Subject: sh: crash kernel resource fix
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=34894c7843e00972d88b3592027703d4e05a06a7;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

sh: crash kernel resource fix

The reserved crash kernel memory range is currently missing from
/proc/iomem. crashk_res is mistakenly setup after __add_active_range().
Reorder things to make sure the resource shows up in /proc/iomem.
