# 1.2 09-Apr-2020 jdolecek

branches: 1.2.2; 1.2.4;
update to __XEN_INTERFACE_VERSION__ 0x0003020a aka Xen 3.2.10

this brings grant memory v2 support:
- status separated from flags - revoking access needs just memory barrier,
no need for expensive cmpxchg16 any more
- sub-page hypervisor copy-only grants, to be used by xennet(4)
- 64-bit frame, i.e. support for DomU RAM >16TB

the grant table is now always allocated on boot to maximum size, it's now
never grown in runtime; switch back to regular kmem_alloc()/kmem_free()

code now requires v2 support, no compatibility for grant version 1 retained -
Xen v2 support predates all currently supported Xen versions

also interface for baloon changed slightly, code updated
# 1.1 09-Apr-2020 jdolecek

move xen/conf/std.xen to i386/conf/std.xen, it's i386-specific

split off __XEN_INTERFACE_VERSION__ to new xen/conf/std.xenversion
and use from both i386/conf/std.xen and amd64/conf/stf.xen, so that
there is single place for the definition
