db0b8e10a7 Make UEFI booting of 4Kn disks work:
-	convert boot1.efi to corrrectly calculate the lba for what the
	media reports and convert the size based on what FreeBSD uses.
	The existing code would use the 512 byte lba and convert the
	size using 4K byte size.
      -	make fsck_msdosfs read the boot block as 4K so the read doesn't
	fail on a 4Kn drive since FreeBSD will error out parition reads
	of a block.  Make the bpbBytesPerSec check a multiple of 512 since
	it can be 512 or 4K depending on the disk.  This allows fsck to
	pass checking the EFI partition on a 4Kn disk.

To create the EFI file system I used:
	newfs_msdos -F 32 -S 4096 -c 1 -m 0xf8 <partition>
This works for booting 512 and 4Kn disks.

Caveat is that loader.efi cannot read the 4Kn EFI partition.  This isn't
critical right now since boot1.efi will read loader.efi from the ufs
partition.  It looks like loader.efi can be fixed via making some of the
512 bytes reads more flexible.  loader.efi doesn't have trouble reading
the ufs partition.  This is probably a simple fix.

I now have FreeBSD installed on a system with 4Kn drives and tested the
same code works on 512.

1f733a5646 Port the TTM AGP backend to the FreeBSD agp driver and enable AGP support
in the radeonkms driver.

Note: In PCI mode virtual addresses on the graphics card that map to system
RAM are translated to physical addresses by the graphics card itself.   In
AGP mode address translation is done by the AGP chipset so fictitious
addresses appear on the system bus.  For the CPU cache management to work
correctly when the CPU accesses this memory it needs to use the same
fictitious addresses (and let the chipset translate them) instead of using
the physical addresses directly.

8ff1eae10d Fix mbuf leak in IPv6 multicast code.
When multicast capable interface goes away, it leaves multicast groups,
this leads to generate MLD reports, but MLD code does deffered send and
MLD reports are queued in the in6_multi's in6m_scq ifq. The problem is
that in6_multi structures are freed when interface leaves multicast groups
and thread that does deffered send will not take these queued packets.

aa77d52800 filedesc: get rid of atomic_load_acq_int from fget_unlocked
A read barrier was necessary because fd table pointer and table size were
updated separately, opening a window where fget_unlocked could read new size
and old pointer.

This patch puts both these fields into one dedicated structure, pointer to which
is later atomically updated. As such, fget_unlocked only needs data a dependency
barrier which is a noop on all supported architectures.

  vendor ID and the highest supported hypervisor CPUID leaf via
  hv_vendor[] and hv_high variables, respectively.  The hv_vendor[]
  array is also exported via the hw.hv_vendor sysctl.
- Merge the VMWare detection code from tsc.c into the new probe in
  identcpu.c.  Add a VM_GUEST_VMWARE to identify vmware and use that in
  the TSC code to identify VMWare.

and casuword(9), but do not mix value read and indication of fault.

I know (or remember) enough assembly to handle x86 and powerpc.  For
arm, mips and sparc64, implement fueword() and casueword() as wrappers
around fuword() and casuword(), which means that the functions cannot
distinguish between -1 and fault.

On architectures where fueword() and casueword() are native, implement
fuword() and casuword() using fueword() and casuword(), to reduce
assembly code duplication.
