from libarchive.googlecode.com: Add a new "archive_read_disk" API
that provides the important service of reading metadata from the
disk. In particular, this will make it possible to remove all
knowledge of extended attributes, ACLs, etc, from clients such
as bsdtar and bsdcpio.
Closely related, this API also provides pluggable uid->uname
and gid->gname lookup and caching services similar to
the uname->uid and gname->gid services provided by archive_write_disk.
Remember this is also required for correct ACL management.
Documentation is still pending...
ABIs:
- Store the FPU initial control word in the pcb for each thread.
- When first using the FPU, load the initial control word after restoring
the clean state if it is not the standard control word.
- Provide a correct control word for Linux/i386 binaries under
FreeBSD/amd64.
- Adjust the control word returned for fpugetregs()/npxgetregs() when a
thread hasn't used the FPU yet to reflect the real initial control
word for the current ABI.
- The Linux/i386 ABI for FreeBSD/i386 now properly sets the right control
word instead of trashing whatever the current state of the FPU is.

- Enable keyboard autodetection by default for ISA syscons attachments.
- If there are no syscons hints at all, assume there is a single sc0 device
anyway. The console probe will still fail unless a VGA adapter is found.

- Remove the control word parameter to npxinit(). It was always set
to __INITIAL_NPXCW__.
- Remove npx_cleanstate_ready as the cleanstate is always initalized
when it is used.
- Improve the handling of the case when the FPU isn't present. Now
the npx0 device no longer succeeds in its probe so all of npx_attach()
is skipped. Also, we allow this case with SMP (though that shouldn't
actually occur as all i386 systems that support SMP have FPUs) now.
SMP was only an issue back when we had an FPU emulator which was not
per-CPU.
- MFamd64: Clear some of the state in npx_cleanstate rather than leaving
it as garbage.
- MFamd64: When a user thread first uses the FPU, use npx_cleanstate for
the initial FPU state.

into the debugger on test setup failures (otherwise, the console window
just goes away and you can't see what went wrong). On all platforms,
clean up a stray buffer before exiting.
- fpudna() always returned 1 since amd64 CPUs always have FPUs. Change
the function to return void and adjust the calling code in trap() to
assume the return 1 case is the only case.
- Remove fpu_cleanstate_ready as it is always true when it is tested.
Also, only initialize fpu_cleanstate when fpuinit() is called on the BSP.

an alternative program to be used for mounting a file system.
Ideally, all file systems
should be converted to pass string arguments to nmount(), so that
/sbin/mount can handle them. However, certain file systems such as FUSE have
not done this, and want to have their own userland mount programs.
For example, to mount an NTFS file system with the FUSE NTFS driver:
mount -t ntfs -o mountprog=/usr/local/bin/ntfs-3g /dev/acd0 /mnt
or via an fstab entry:
/dev/acd0 /mnt ntfs ro,noauto,mountprog=/usr/local/bin/ntfs-3g 0 0

This is the last phase of the "big decompression refactor" that
puts a lazy reblocking layer between each pair of read filters.
I've also changed the terminology for this area---the two kinds
of objects are now called "read filters" and "read filter bidders"---and
moved ownership of these objects to the archive_read core.
This greatly simplifies implementing new read filters, which
can now use peek/consume I/O semantics both for bidding (arbitrary
look-ahead!) and for reading streams (look-ahead simplifies handling
concatenated streams, for instance).
The first merge here is the overhaul proper; the remainder are small
fixes to correct errors in the initial implementation.
BAR could be allocated twice by different children of a vgapci0 device.
To fix this, change the vgapci0 device to track references on its associated
resources so that they are only allocated once from the parent PCI bus and
released when no children are using them. Previously this leaked a small
amount of KVA on at least some architectures.

We now explicitly enable INTx during bus_setup_intr() if it is needed.
Several of the ata drivers were managing this bit internally. This is
better handled in pci and it should work for all drivers now.
We also mask INTx during bus_teardown_intr() by setting this bit.
