[PATCH v2 0/4] xen/arch: Simplify virtual_region setup

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

There is nothing that setup_virtual_regions() does which can't be done at
build time.  Make this happen.

Importantly, this removes logic from needed prior to setting up exceptions.

v2:
 * Only minor changes in patches 3 and 4.

Andrew Cooper (4):
  xen/link: Introduce a common BUGFRAMES definition
  xen/virtual-region: Rework how bugframe linkage works
  xen/virtual-region: Link the list build time
  xen/virtual-region: Drop setup_virtual_regions()
