Subject: [PATCH] x86_64: add __meminit for memory hotplug
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c09b42404d29c8a9266f8186632330dc8474bf2e;p=openwrt%2Fstaging%2Fblogic.git

[PATCH] x86_64: add __meminit for memory hotplug

Add __meminit to the __init lineup to ensure functions default
to __init when memory hotplug is not enabled.  Replace __devinit
with __meminit on functions that were changed when the memory
hotplug code was introduced.
