From 5f0ababbf49f12330effab932a18055a50f4c0a1 Mon Sep 17 00:00:00 2001 From: Isaku Yamahata Date: Wed, 2 Apr 2008 10:53:59 -0700 Subject: xen: replace callers of alloc_vm_area()/free_vm_area() with xen_ prefixed one Don't use alloc_vm_area()/free_vm_area() directly, instead define xen_alloc_vm_area()/xen_free_vm_area() and use them. alloc_vm_area()/free_vm_area() are used to allocate/free area which are for grant table mapping. Xen/x86 grant table is based on virtual address so that alloc_vm_area()/free_vm_area() are suitable. On the other hand Xen/ia64 (and Xen/powerpc) grant table is based on pseudo physical address (guest physical address) so that allocation should be done differently. The original version of xenified Linux/IA64 have its own allocate_vm_area()/free_vm_area() definitions which don't allocate vm area contradictory to those names. Now vanilla Linux already has its definitions so that it's impossible to have IA64 definitions of allocate_vm_area()/free_vm_area(). Instead introduce xen_allocate_vm_area()/xen_free_vm_area() and use them.
