Subject: [PATCH 0/9] x86/init: replace paravirt_enabled() were possible

I originally set out to rename paravirt_enabled() to paravirt_legacy()
but we instead decided to remove paravirt_enabled() completely. Although
I have some linker table work which will help make this cleaner, instead
of waiting for that to go in, just remove the known cases that should
be safe for paravirt_enabled() and also replace it for the subarch
use.

While at it, document the subarch to avoid any possible misuses.

Luis R. Rodriguez (9):
  x86/boot: enumerate documentation for the x86 hardware_subarch
  tools/lguest: make lguest launcher use X86_SUBARCH_LGUEST explicitly
  x86/xen: use X86_SUBARCH_XEN for PV guest boots
  x86/init: make ebda depend on PC subarch
  apm32: remove paravirt_enabled() use
  x86/tboot: remove paravirt_enabled()
  x86/cpu/intel: replace paravirt_enabled() for f00f work around
  x86/rtc: replace paravirt_enabled() check with subarch check
  pnpbios: replace paravirt_enabled() check with subarch checks
