Introduce vm_guest_is_pvh() and use it in place of
	(vm_guest == VM_GUEST_XENPVH || vm_guest == VM_GUEST_GENPVH)

Add support for non-Xen PVH guests to amd64. Patch from
Emile 'iMil' Heitor in PR kern/57813, with some cosmetic tweaks by me.
Tested on bare metal, Xen PV and Xen PVH by me.

Fix locking after opendisk(), VOP_IOCTL() needs an unlocked vnode,
vn_rdwr() needs flag IO_NODELOCKED.

sys: Fix various abuse of struct device internals.

Will help to make struct device opaque later.

KNF. No functional change.

Adapt to proplib api changes

whitelist -> permitlist

Introduce Xen PVH support in GENERIC.
This is compiled in with
options XENPVHVM
x86 changes:
- add Xen section and xen pvh entry points to locore.S. Set vm_guest
  to VM_GUEST_XENPVH in this entry point.
  Most of the boot procedure (especially page table setup and switch to
  paged mode) is shared with native.
- change some x86_delay() to delay_func(), which points to x86_delay() for
  native/HVM, and xen_delay() for PVH

Xen changes:
- remove Xen bits from init_x86_64_ksyms() and init386_ksyms()
  and move to xen_init_ksyms(), used for both PV and PVH
- set ISA no-legacy-devices property for PVH
- factor out code from Xen's cpu_bootconf() to xen_bootconf()
  in xen_machdep.c
- set up a specific pvh_consinit() which starts with printk()
  (which uses a simple hypercall that is available early) and switch to
  xencons when we can use pmap_kenter_pa().

Add xbd to the list of valid disks.
Remove hardcoded root on xbd0 for Xen PVHVM, now that the x86 findroot()
knowns about xbd disks.

Merge the bouyer-xenpvh branch, bringing in Xen PV drivers support under HVM
guests in GENERIC.
Xen support can be disabled at runtime with
boot -c
disable hypervisor

in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT

Added drivers for Hyper-V Synthetic Keyboard and Video device.

In device_register(), if the device is an "iic" child of "imcsmb",
attach a I2C_PROP_INDIRECT_DEVICE_WHITELIST property that limits
the allowed devices to "spdmem" and "sdtemp".  Also set the
I2C_PROP_INDIRECT_PROBE_STRATEGY property to I2C_PROBE_STRATEGY_NONE,
since that controller can't issue any of the "quick" commands.

XXX It would be nice to be able to do this in the imcsmb driver
itself, but the way autoconfiguration works makes that infeasible.

Don't report EINVAL errors when searching the bootwedge, this error
is most likely the result of reading beyond the end of the wrong disk.

If BTINFO_ROOTDEVICE is set but isn't a device name, then treat it

- prevent matchbiosdisks from being called twice. This could happen
  via raid autoconf calling cpu_rootconf() once and then init main
  calling cpu_rootconf() a second time.
- separate booted_device setup into cpu_bootconf(), a new optional function.
  This function can be called before raid autoconfiguration to determine
  the booted device. This needs to be done before raid autoconfiguration,
  otherwise if we are using wedges, the raid will autoconfigure wedges,
  and we'll be unable to open the underlying devices later to determine
  the booted device.

A pointer typedef entails trading too much flexibility to declare const

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

Extract common code from i386, xen, and sparc64, creating
config_handle_wedges() and read_disk_sectors().  On x86, handle_wedges()
is a thin wrapper for config_handle_wedges().  Share opendisk()
across architectures.

Add kernel code in support of specifying a root partition by wedge
name.  E.g., root specifications "wedge:wd0a", "wedge:David's Root
Volume" are possible.  (Patches for config(1) coming soon.)

In support of moving disks between architectures (esp. i386 <->
evbmips), I've written a routine convertdisklabel() that ensures
that the raw partition is at RAW_DISK by following these steps:

        0 If we have read a disklabel that has a RAW_PART with
          p_offset == 0 and p_size != 0, then use that raw partition.

        1 If we have read a disklabel that has both partitions 'c'
          and 'd', and RAW_PART has p_offset != 0 or p_size == 0,
          but the other partition is suitable for a raw partition
          (p_offset == 0, p_size != 0), then swap the two partitions
          and use the new raw partition.

        2 If the architecture's raw partition is 'd', and if there
          is no partition 'd', but there is a partition 'c' that
          is suitable for a raw partition, then copy partition 'c'
          to partition 'd'.

        3 Determine the drive's last sector, using either the
          d_secperunit the drive reported, or by guessing (0x1fffffff).
          If we cannot read the drive's last sector, then fail.

        4 If we have read a disklabel that has no partition slot
          RAW_PART, then create a partition RAW_PART.  Make it span
          the whole drive.

        5 If there are fewer than MAXPARTITIONS partitions,
          then "slide" the unsuitable raw partition RAW_PART, and
          subsequent partitions, into partition slots RAW_PART+1
          and subsequent slots.  Create a raw partition at RAW_PART.

The convertdisklabel() procedure can probably stand to be simplified,
but it ought to deal with all but an extraordinarily broken disklabel,
now.

handle_wedges: fix a typo.  (NOCREAD -> NOCRED)

I can not test this right now, but the equivalent change was needed on
sparc64 to make root on raid shutdown cleanly: after using opendisk()
and querying wedges, we need to VOP_CLOSE() the resulting vnode.

Fix missing initialization of tmpvn; thanks gcc.

- Check if a disk has wedges, and use the wedge device corresponding to the
  root partition, instead of punting. This makes booting work
  with traditional disklabel disks and wedge autoconfiguration.
- factor out disk opening code.

Revert yesterday's change that attempted to fix the detection of the
boot device when using a Multiboot boot loader.  It couldn't work because
these boot loaders do not pass a checksum of the disk so matchbiosdisk()
cannot really find any matches.  I should have gone to sleep before
commiting...

Found by xtraeme@.

When booting an i386 kernel with Multiboot, properly detect the boot device
by looking it up in the x86_alldisks table (instead of trying to match it
to 'wd*' manually).

In order to do this, move the cpu_rootconf function from x86 common code
to amd64 and i386 specific one.  This way, i386 can do an extra step (call
the appropriate Multiboot code) in the appropriate place (after
x86_matchbiosdisks and before findroot()).

Implement support for 'The Multiboot Specification' so that i386 kernels
can be booted directly from Multiboot-compliant boot loaders (e.g. GRUB).
See the added multiboot(8) manual page for more information.

No objections in tech-kern@; only positive comments.

Fix typo: labe -> label.

Use the new BTINFO_BOOTWEDGE bootinfo to discover the booted disk and

Move boot device detection code from i386 and amd64 ports to x86_autoconf.c.
Rename i386_alldisks and x86_64_alldisks to x86_alldisks, adjust other
references to compensate.
