05b6a20a66 - Hold the vnode used in the statfs related functions until we're done with
the VFS_STATFS call to prevent the mount from disappearing while we're
   stating.
 - Convert these routines to use MPSAFE namei semantics.

f5cacb3964 - spell VOP_LOCK(vp, LK_RELEASE... VOP_UNLOCK(vp,... so that asserts in
vop_lock_post do not trigger.
 - Rearrange null_inactive to null_hashrem earlier so there is no chance
   of finding the null node on the hash list after the locks have been
   switched.
 - We should never have a NULL lowervp in null_reclaim() so there is
   no need to handle this situation.  panic instead.

9c12e63100 - Assert that the lowervp is locked in null_hashget().
- Simplify the logic dealing with recycled vnodes in null_hashget() and
   null_hashins().  Since we hold the lower node locked in both cases
   the null node can not be undergoing recycling unless reclaim somehow
   called null_nodeget().  The logic that was in place was not safe and
   was essentially dead code.

ca95b5146a Lock the vm_object while checking its type to see if it is a vnode-backed
object that requires Giant in vm_object_deallocate().  This is somewhat
hairy in that if we can't obtain Giant directly, we have to drop the
object lock, then lock Giant, then relock the object lock and verify that
we still need Giant.  If we don't (because the object changed to OBJT_DEAD
for example), then we drop Giant before continuing.

6fc6433ecd Split calcru() back into a calcru1() function shared with calccru() and
a calcru() wrapper that passes a local rusage_ext on the stack that is
a snapshot to do the calculations on.  Now we can pass p->p_crux to
calcru1() in calccru() again which fixes the issues with runtime going
backwards messages when dead processes are harvested by init.

0c05ab41ab - In the interrupt handler clear the interrupt source flags before
processing the interrupt events. If we clear them afterwards we
  can completely miss some events as the NIC can change the source
  flags while we're in the handler. In order to not get another
  interrupt while we're in ifp->if_input() with the driver lock
  dropped we now turn off NIC interrupts while in the interrupt
  handler. Previously this was meant to be achieved by clearing the
  interrupt source flags after processing the interrupt events but
  didn't really work as clearing these flags doesn't actually
  acknowledge and re-enable the events.
  This fixes the device timeouts seen with the VMware LANCE.
- Relax the watchdog timer somewhat; don't enable it until the last
  packet is enqueued and if there is a TX interrupt but there are
  still outstanding ones reload the timer.

b2fc195e1b 10GbE mode driver and binary firmware for Myricom's PCI-express NICs.
More info regarding these nics can be found at http://www.myri.com.

Please note that the files
sys/dev/myri10ge/{mcp_gen_header.h,myri10ge_mcp.h} are internally
shared between all our drivers (solaris, macosx, windows, linux, etc).
I'd like to keep these files unchanged, so I can just import newer
versions of them when the firmware API/ABI changes.  This means I'm
stuck with some of the crazy-long #define names, and possibly
non-style(9) characteristics of these files.

Many thanks to mlaier for doing firmware(9) just as I
needed it, and to scottl for his helpful review.

9789208431 - Don't bother traversing trap frames in stack_save(). This fixes panics
when option DEBUG_LOCKS is used. Trap frames are determined by checking
  whether the caller was one of the tl0_*() or tl1_*() asm functions via
  a newly added pair of dummy symbols in exception.S which mark the begin
  and end of these functions. The tl_trap_* pair marks those in the special
  .trap section and the tl_text_* in the regular .text section. Because
  of their performance penalty db_search_symbol()/db_symbol_values() and
  linker_ddb_search_symbol()/linker_ddb_symbol_values() aren't used here
  for determining the caller, with db_search_symbol()/db_symbol_values()
  additionally not being reentrant.
- For consistency, change db_backtrace() to also use the new markers for
  determining the tl0_*() and tl1_*() asm functions instead of bcmp()'ing
  the symbol name.
- Use FBSDID in db_trace.c.

c0d157d85f For the coda5 module, CODA_COMPAT_5 is mandatory, not optional.
Without CODA_COMPAT_5, it would be equivalent to the plain coda
module.  Therefore just add -DCODA_COMPAT_5 to CFLAGS instead of
fiddling with opt_coda.h.  This is particularly important when
the module is built along with the kernel and CODA_COMPAT_5 isn't
in the kernel conf file (and so not in opt_coda.h either).
