[PATCH 0/5] x86: mostly shadow related XSA-319 follow-up

[Jan Beulich <jbeulich@xxxxxxxx>]

This in particular goes a few small steps further towards proper
!HVM and !PV config handling (i.e. no carrying of unnecessary
baggage).

1: x86/shadow: dirty VRAM tracking is needed for HVM only
2: x86/shadow: shadow_table[] needs only one entry for PV-only configs
3: x86/PV: drop a few misleading paging_mode_refcounts() checks
4: x86/shadow: have just a single instance of sh_set_toplevel_shadow()
5: x86/shadow: l3table[] and gl3e[] are HVM only
