Subject: [PATCH] uml: fix hardcoded ZONE_* constants in zone setup
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=353f8d1cd5b8540c1591f00a5cbd3aeca699cfcf;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[PATCH] uml: fix hardcoded ZONE_* constants in zone setup

Remove usage of hardcoded constants in paging_init().

By chance I spotted a bug in zones_setup involving a change to ZONE_*
constants, due to the ZONE_DMA32 patch from Andi Kleen (which is in -mm).
So, possibly, instead of zones_size[2] you will find zones_size[3] in the
code, but that change is wrong and this patch is still correct.
