Subject: mm/page_owner.c: make early_page_owner_param() __init
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=1173194e1e932e4aa9ce4b0ecac72446482f0e4f;p=openwrt%2Fstaging%2Fblogic.git

mm/page_owner.c: make early_page_owner_param() __init

The early_param() is only called during kernel initialization, So Linux
marks the functions of it with __init macro to save memory.

But it forgot to mark the early_page_owner_param().  So, Make it __init
as well.
