Allocate pages for symlink file from Normal zone, as the pages might be
searched in radix-trees several times in one systemcall. However the
migration code assumes every page is searched once.

FIXME:
	This code is temporary, the base code assumes HighMem is
	hot-pluggable. The pages should be allocated from non hot-pluggable
	zone or non hot-pluggable memory area, not from Normal zone.

	Or make pages for symlink files hot-pluggable to remove
	this code.
