[Xen-devel] [PATCH] Add 2M page support to Xen balloon driver

[Dave McCracken <dcm@xxxxxxxx>]

This patch adds a kernel command line option "balloon_hugepages" that, when 
enabled, will make the balloon driver work in 2M pages (ie hugepages).  This 
will work in conjunction with the "superpages" domain creation option so once 
a domain is created with 2M contiguous pages it will continue to free and re-
allocate at the 2M page size.

Note that the current hypervisor code does not allow 2M page allocations for 
all guest domains.  Keir has agreed to change the hypervisor to allow them, 
but for now "balloon_hugepages" should only be specified on hypervisors that 
have this change.
