1af1c6cd8a Wait until after dropping the receive socket buffer lock to allocate space

This reduces contention on the lock and CPU system time in certain UDP
workloads.

e1e93f9fb3 Remove function prototypes of nonexistent TTY functions.
It turns out I overlooked some function prototypes that were actually
TTY related, but were stored in <sys/conf.h> to implement the D_TTY
flag. Remove these prototypes now that they don't exist anymore.

88843c5481 Update to Myri10GE firmware version 1.4.33 from 1.4.29. Relevant changes include:
- Support for Myricom 10G-PCIE-8B NICs

- multi-slice firmware: fix a bug when the presence of 32-bit or
 64-bit DMA addresses for interrupt queues and data is not uniform across
 slices.

- Improves automatic selection between ethp_z8e/eth_z8e

46ceb66ad3 - Make gvinum header on-disk structure consistent on all platforms by storing
the gvinum header in fields of fixed size and in a big endian byte order
  rather than the size and byte order of the actual platform.

Note that the change is backwards compatible with the old gvinum configuration
format, but will save the configuration in the new format when the 'saveconfig'
command is executed.

25edc6dd20 Various cleanups for soreceive_dgram():
- Update or remove comments that were left over from the original
  soreceive_generic() implementation.  Quite a few were misleading in the
  context of the new code.
- Since soreceive_dgram() has a simpler structure, replace several gotos
  with a while loop making the invariants more clear.
- In the blocking while loop, don't try to handle cases incompatible with
  the loop invariant (since m is always NULL, don't check for and handle
  non-NULL).
- Don't drop and re-acquire the socket buffer lock unnecessarily after
  sbwait() returns, which may help reduce lock contention (etc).
- Assume PR_ATOMIC since we assert it at the top of the function.

9e035bb343 Remove critical_enter() and critical_exit(): pmap_growkernel is called
with kernel_map->system_mtx held so these aren't needed.  Add an
assertion to make sure this is the case.

Also, fix a minor style(9) nit.

0c0903b1e1 Improve support for multiple block read/write. This code is currently
disabled by default because there's problems with it on AT91RM9200,
currently the only host controller in the tree.  I've not had time to
track those problems to ground.  I'm committing because this is
important for other host controllers that are in the pipeline.

e2b2d0e9d5 vm_fault_hold_user_pages will not return if an address in the range passed in is mapped RO
but an RW mapping exists for the underlying page. This change fixes the bug by using the
page / NULL returned from pmap_extract_and_hold to determine whether or not vm_fault needs
to be called.

The bug was pointed out by alc.

a87faebb8c Return G_PART_PROBE_PRI_HIGH instead of G_PART_PROBE_PRI_NORM
if the probe succeeds. This guarantees that the BSD scheme
wins over the MBR scheme when MBR gets to probe first. Build-
or link-time conditions can cause schemes to end up in the
linker set in a different order. Normally BSD is before MBR
in the linker set and as such get to probe first. But typically
when the kernel gets rebuild or relinked, this can change.
