[PATCH] x86_64: Fixed guard page handling again in iounmap
Caused oopses again. Also fix potential mismatch in checking if
change_page_attr was needed.
To do it without races I needed to change mm/vmalloc.c to export a
__remove_vm_area that does not take vmlist lock.
Noticed by Terence Ripperda and based on a patch of his.
