89ab2a7a53 Update the list of Cx states when ACPICA notifies us. Usually, this
notification is sent when the AC plug is plugged in/out.

This is required on some laptops, namely the MacBooks.

e058c00c40 Updates for changes in the way printf() handles hex floating point
numbers.

76303a9735 Make several changes to the way printf handles hex floating point (%a):
1. Previously, printing the number 1.0 could produce 0x1p+0, 0x2p-1,
   0x4p-2, or 0x8p-3, depending on what happened to be convenient. This
   meant that printing a value as a double and printing the same value
   as a long double could produce different (but equivalent) results.
   The change is to always make the leading digit a 1, unless the
   number is 0. This solves the aforementioned problem and has
   several other advantages.

2. Use the FPU to do rounding. This is far simpler and more portable
   than manipulating the bits, and it fixes an obsure round-to-even
   bug. It also raises the exceptions now required by IEEE 754R.
   The drawbacks are that it is usually slightly slower, and it makes
   printf less effective as a debugging tool when the FPU is hosed
   (e.g., due to a buggy softfloat implementation).

3. On i386, twiddle the rounding precision so that (2) works properly
   for long doubles.

4. Make several simplifications that are now possible due to (2).

5. Split __hldtoa() into a separate file.

flags appropriately. The next step is to make it raise a SIGFPE if
any exceptions are unmasked.

46c3c836b6 - Fixed a problem with the send chain consumer index which would cause
TX traffic to sit in the send chain until a received packet kick
  started the interrupt handler.  This would cause extremely slow
  performance when used with NFS over UDP.
- Removed untested polling code.
- Updated copyright year in the file header.
- Removed inadvertent ^M's created by DOS text editor.

b300d706ea - Use a lockmgr lock rather than a mtx to protect dirhash. This lock
may be held for the duration of the various dirhash operations which
   avoids many complex unlock/lock/revalidate sequences.
 - Permit shared locks on lookup.  To protect the ip->i_dirhash pointer we
   use the vnode interlock in the shared case.  Callers holding the
   exclusive vnode lock can run without fear of concurrent modification to
   i_dirhash.
 - Hold an exclusive dirhash lock when creating the dirhash structure for
   the first time or when re-creating a dirhash structure which has been
   recycled.

eb1314a249 - cache dp->i_offset in the local 'i_offset' variable for use in loop
indexes so directory lookup becomes shared lock safe.  In the modifying
   cases an exclusive lock is held here so the commit routine may
   rely on the state of i_offset.
 - Similarly handle i_diroff by fetching at the start and setting only once
   the operation is complete.  Without the exclusive lock these are only
   considered hints.
 - Assert that an exclusive lock is held when we're preparing for a commit
   routine.
 - Honor the lock type request from lookup instead of always using exclusive
   locking.

42b1030bbd Optimize package registration/deregistration. Previously, when looking up the
package name for the origin of a dependency, all entries in /var/db/pkg were
traversed for each dependency of added/removed package.  Now, gather all the
origins first, then do the lookup in a single pass over /var/db/pkg.

This should provide a major speedup for packages with hundreds of dependencies.

44b779b337 Identify ICH9 USB controllers.
I've taken a slightly different approach than is used with the ICH8 controllers
in that each controller is not identified individually (eg USB A, USB B, etc).
Instead I've given then same description to each one even though the device ID
differs.  This can easily be changed if desired, or ICH8 (and any others using
that approach) can be made to work as this does.

9b33b154b5 - Add the interrupt vector number to intr_event_create so MI code can
lookup hard interrupt events by number.  Ignore the irq# for soft intrs.
 - Add support to cpuset for binding hardware interrupts.  This has the
   side effect of binding any ithread associated with the hard interrupt.
   As per restrictions imposed by MD code we can only bind interrupts to
   a single cpu presently.  Interrupts can be 'unbound' by binding them
   to all cpus.

14320f1e7f Add a new flag, '-C' which enables a special mode that is intended for
catastrophic recovery.  Currently, this mode only validates whether a
cylindergroup has good signature data, and prompts the user to decide
whether to clear it as a whole.

This mode is useful when there is data damage on a disk and you are
working on copy of the original disk, as fsck_ffs(8) tends to abnormally
exit in such case, as a last resort to recover data from the disk.

The bug was unnoticed on non-i386 because mp_maxid is

f4d2c7f13e Correct pmap_copy()'s method for extracting the physical address of a
2/4MB page from a PDE.  Specifically, change it to use PG_PS_FRAME,
not PG_FRAME, to extract the physical address of a 2/4MB page from a
PDE.

Change the last argument passed to pmap_pv_insert_pde() from a
vm_page_t representing the first 4KB page of a 2/4MB page to the
vm_paddr_t of the 2/4MB page.  This avoids an otherwise unnecessary
conversion from a vm_paddr_t to a vm_page_t in pmap_copy().

1375f576a9 It seems that RealTek 8129/8139 chip reports invalid length of
received frame under certain conditions. wpaul said the length
0xfff0 is special meaning that indicates hardware is in the
process of copying a packet into host memory. But it seems
there are other cases that hardware is busy or stuck in bad
situation even if the received frame length is not 0xfff0.
To work-around this condition, add a check that verifys that
recevied frame length is in valid range. If received length is out
of range reinitialize hardware to recover from stuck condition.
