Subject: sparc64: Fix prototype warning for vmemmap_free
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=39e5611bf756416b90be7da64737760a82a5576b;p=linux.git

sparc64: Fix prototype warning for vmemmap_free

Fix the following warning:
arch/sparc/mm/init_64.c:2644:6: warning: no previous prototype for ‘vmemmap_free’

The function vmemmap_free() is only used for systems with
CONFIG_MEMORY_HOTPLUG defined - and sparc64 do not support this.
Drop the empty function as it has no users.
