687adb703d Refactor the name hash and the ID hash, that are used to address nodes:
- Make hash sizes growable, to satisfy users running large mpd
  installations, having thousands of nodes.
- NG_NAMEHASH() proved to give a very bad distribution in real life
  name sets, while generic hash32_str(name, HASHINIT) proved to give
  an even one, so you the latter for name hash.
- Do not store unnamed nodes in slot 0 of name hash, no reason for that.
- Use the ID hash in cases when we need to run through all nodes: the
  NGM_LISTNODES command and in the vnet_netgraph_uninit().
- Implement NGM_LISTNODES and NGM_LISTNAMES as separate code, the former
  iterates through the ID hash, and the latter through the name hash.
- Keep count of all nodes and of named nodes, so that we don't need
  to count nodes in NGM_LISTNODES and NGM_LISTNAMES. The counters are
  also used to estimate whether we need to grow hashes.
- Close a race between two threads running ng_name_node() assigning same
  name to different nodes.

4ba4ebd0a8 Clean up RFLAG and CR3 register handling and nearby comments. For BSP, use
spinlock_enter()/spinlock_exit() to save/restore RFLAGS.  We know interrupt
is disabled when returning from S3.  For AP, we do not have to save/restore
it because IRET will do it for us any way.  Do not save CR3 locally because
savectx() does it and BSP does not have to switch to kernel map for amd64.

5644ccec61 (This commit only touches code within the DEV_NETMAP blocks)
Introduce some functions to map NIC ring indexes into netmap ring
indexes and vice versa. This way we can implement the bound
checks only in one place (and hopefully in a correct way).

On passing, make the code and comments more uniform across the
various drivers.

d8951c8a2f Fix PAWS (Protect Against Wrapped Sequence numbers) in cases when
hz >> 1000 and thus getting outside the timestamp clock frequenceny of
1ms < x < 1s per tick as mandated by RFC1323, leading to connection
resets on idle connections.

Always use a granularity of 1ms using getmicrouptime() making all but
relevant callouts independent of hz.

Use getmicrouptime(), not getmicrotime() as the latter may make a jump
possibly breaking TCP nfsroot mounts having our timestamps move forward
for more than 24.8 days in a second without having been idle for that
long.

8b8bfa3567 Enhance documentation, improve interoperability, and fix defects in
FreeBSD's front and back Xen blkif interface drivers.

sys/dev/xen/blkfront/block.h:
sys/dev/xen/blkfront/blkfront.c:
sys/dev/xen/blkback/blkback.c:
	Replace FreeBSD specific multi-page ring impelementation with
	support for both the Citrix and Amazon/RedHat versions of this
	extension.

sys/dev/xen/blkfront/blkfront.c:
	o Add a per-instance sysctl tree that exposes all negotiated
	  transport parameters (ring pages, max number of requests,
	  max request size, max number of segments).
	o In blkfront_vdevice_to_unit() add a missing return statement
	  so that we properly identify the unit number for high numbered
	  xvd devices.

sys/dev/xen/blkback/blkback.c:
	o Add static dtrace probes for several events in this driver.
	o Defer connection shutdown processing until the front-end
	  enters the closed state.  This avoids prematurely tearing
	  down the connection when buggy front-ends transition to the
	  closing state, even though the device is open and they
	  veto the close request from the tool stack.
	o Add nodes for maximum request size and the number of active
	  ring pages to the exising, per-instance, sysctl tree.
	o Miscelaneous style cleanup.

sys/xen/interface/io/blkif.h:
	o Add extensive documentation of the XenStore nodes used to
	  implement the blkif interface.
	o Document the startup sequence between a front and back driver.
	o Add structures and documenatation for the "discard" feature
	  (AKA Trim).
	o Cleanup some definitions related to FreeBSD's request
	  number/size/segment-limit extension.

sys/dev/xen/blkfront/blkfront.c:
sys/dev/xen/blkback/blkback.c:
sys/xen/xenbus/xenbusvar.h:
	Add the convenience function xenbus_get_otherend_state() and
	use it to simplify some logic in both block-front and block-back.

79f9811409 When initialising the CP0 status register during boot on 64-bit MIPS,
set all three of the kernel, supervisor, and user-mode 64-bit mode
flags.  While FreeBSD does not currently use the supervisor ring (and
hence this is effectively a NOP on most systems), doing this avoids
triggering an exception on 64-bit MIPS CPUs that don't support 32-bit
compatibility mode, and therefore don't allow clearing the SX bit.

- Add a __NO_TLS flag to cdefs.h to indicate where not available.
- Reorganise the xlocale.h definitions into xlocale/*.h so that they can be
  included from multiple places.
- Export the POSIX2008 subset of xlocale when POSIX2008 says it should be
  exported, independently of whether xlocale.h is included.
- Fix the bug where programs using ctype functions always assumed ASCII unless
  recompiled.
- Fix some style(9) violations.

5525b53de5 Do not handle MOD_SHUTDOWN equally to MOD_UNLOAD in sound kernel module.
MOD_SHUTDOWN is not an end of existence, and there is a life after it.
In particular, code previously called on MOD_SHUTDOWN grabbed lock and
deallocated unit numbering. That caused infinite wait loop if snd_uaudio
tried to destroy its PCM device after that point.

bb631bf94d - As it turns out, MSI-X is broken for at least LSI SAS1068E when passed
through by VMware so blacklist their PCI-PCI bridge for MSI/MSI-X here.
  Note that besides currently there not being a quirk type that disables
  MSI-X only and there's no evidence that MSI doesn't work with the VMware
  pass-through, it's really questionable whether MSI generally works in
  that setup as VMware only mention three know working devices [1, p. 4].
  Also not that this quirk entry currently doesn't affect the devices
  emulated by VMware in any way as these don't claim support MSI/MSI-X to
  begin with. [2]
  While at it, make the PCI quirk table const and static.
- Remove some duplicated empty lines.
- Use DEVMETHOD_END.
