e45d37b2e9 Don't attempt to write label with GEOM_BSD based method if the class is 
not available. This improves error reporting when bsdlabel(8) is unable
to open a device for writing. If GEOM_BSD was unavailable, only a rather
obscure error message "Class not found" was printed.

0778b1d117 - Check the result of malloc(M_NOWAIT) in replay_alloc(). The caller 
(replay_alloc()) knows how to handle replay_alloc() failure.
- Eliminate 'freed_one' variable, it is not needed - when no entry is found
  rce will be NULL.

a73f383ee9 Add an experimental feature to shadow video BIOS. Long ago, this trick was 
supported by many BIOSes to improve performance of VESA BIOS calls for real
mode OSes but it is not our intention here.  However, this may help some
platforms where the video ROMs are inaccessible after suspend, for example.
Note it may consume up to 64K bytes of contiguous memory depending on video
controller model when it is enabled.  This feature can be disabled by
setting zero to 'debug.vesa.shadow_rom' loader tunable via loader(8) or
loader.conf(5).  The default is 1 (enabled), for now.

c2175767b7 Intel QPI chipsets actually provide two extra "non-core" PCI buses that 
provide PCI devices for various hardware such as memory controllers, etc.
These PCI buses are not enumerated via ACPI however.  Add qpi(4) psuedo
bus and Host-PCI bridge drivers to enumerate these buses.  Currently the
driver uses the CPU ID to determine the bridges' presence.
