# HG changeset patch
# User awilliam@xxxxxxxxxxx
# Node ID 827c65c06a66dd067c64ebb56b17b4379d83cbf9
# Parent 0a6f5527ca4bd560fc5c750e7ade3a0040144e40
[IA64] Add memory operations for xen/ia64
This patch removes ugly hack upon memory operation and thus
allow inc/decrease_reservation op available for xen/ia64 now.
As a result:
* Now we conform to common sequence where all domain pages
are allocated together by increase_reservation before
image builder
* physmap table is now built at point of arch_set_info_guest
* DOM0_GETMEMLIST can only query without allocation now
After this patch, some long-existing hacks due to mismatched
memory interface are cleaned this time. Also this is a base
step toward introducing balloon feature into xen/ia64.
