ed10c810db Due to space constraints, the UFS boot2 and boot1 use an evil hack where
boot2 calls back into boot1 to perform disk reads.  The ZFS MBR boot blocks
do not have the same space constraints, so remove this hack for ZFS.
While here, remove commented out code to support C/H/S addressing from
zfsldr.  The ZFS and GPT bootstraps always just use EDD LBA addressing.

2be767e069 Add the watchdogs patting during the (shutdown time) disk syncing and
disk dumping.
With the option SW_WATCHDOG on, these operations are doomed to let
watchdog fire, fi they take too long.

I implemented the stubs this way because I really want wdog_kern_*
KPI to not be dependant by SW_WATCHDOG being on (and really, the option
only enables watchdog activation in hardclock) and also avoid to
call them when not necessary (avoiding not-volountary watchdog
activations).

9e880b876d Sync with several changes in UFS/FFS:
- 77115: Implement support for O_DIRECT.
- 98425: Fix a performance issue introduced in 70131 that was causing
  reads before writes even when writing full blocks.
- 98658: Rename the BALLOC flags from B_* to BA_* to avoid confusion with
  the struct buf B_ flags.
- 100344: Merge the BA_ and IO_ flags so so that they may both be used in
  the same flags word. This merger is possible by assigning the IO_ flags
  to the low sixteen bits and the BA_ flags the high sixteen bits.
- 105422: Fix a file-rewrite performance case.
- 129545: Implement IO_INVAL in VOP_WRITE() by marking the buffer as
  "no cache".
- Readd the DOINGASYNC() macro and use it to control asynchronous writes.
  Change i-node updates to honor DOINGASYNC() instead of always being
  synchronous.
- Use a PRIV_VFS_RETAINSUGID check instead of checking cr_uid against 0
  directly when deciding whether or not to clear suid and sgid bits.

cd0f42fa9f Re-enable the wireless build parameters for the AR9130 WMAC.
* enable 11n

9f25ad52ce Introduce AR9130 (HOWL) WMAC support to the FreeBSD HAL.
The AR9130 is an AR9160/AR5416 family WMAC which is glued directly
to the AR913x SoC peripheral bus (APB) rather than via a PCI/PCIe
bridge.

The specifics:

* A new build option is required to use the AR9130 - AH_SUPPORT_AR9130.
  This is needed due to the different location the RTC registers live
  with this chip; hopefully this will be undone in the future.
  This does currently mean that enabling this option will break non-AR9130
  builds, so don't enable it unless you're specifically building an image
  for the AR913x SoC.

* Add the new probe, attach, EEPROM and PLL methods specific to Howl.

* Add a work-around to ah_eeprom_v14.c which disables some of the checks
  for endian-ness and magic in the EEPROM image if an eepromdata block
  is provided. This'll be fixed at a later stage by porting the ath9k
  probe code and making sure it doesn't break in other setups (which
  my previous attempt at this did.)

* Sprinkle Howl modifications throughput the interrupt path - it doesn't
  implement the SYNC interrupt registers, so ignore those.

* Sprinkle Howl chip powerup/down throughout the reset path; the RTC methods
  were

* Sprinkle some other Howl workarounds in the reset path.

* Hard-code an alternative setup for the AR_CFG register for Howl, that
  sets up things suitable for Big-Endian MIPS (which is the only platform
  this chip is glued to.)

This has been tested on the AR913x based TP-Link WR-1043nd mode, in
legacy, HT/20 and HT/40 modes.

Caveats:

* 2ghz has only been tested. I've not seen any 5ghz radios glued to this
  chipset so I can't test it.

* AR5416_INTERRUPT_MITIGATION is not supported on the AR9130. At least,
  it isn't implemented in ath9k. Please don't enable this.

* This hasn't been tested in MBSS mode or in RX/TX block-aggregation mode.

8adcbaed13 Only align MSI message groups based on the number of messages being
allocated, not the maximum number of messages the device supports.  The
spec only requires the former, and I believe I implemented the latter due
to misunderstanding an e-mail.  In particular, this fixes an issue where
having several devices that all support 16 messages can run out of
IDT vectors on x86 even though the driver only uses a single message.

7b67bd9f3d This patch is believed to fix a problem in the kernel rpc for
non-interruptible NFS mounts, where a kernel thread will seem
to be stuck sleeping on "rpccon". The msleep() in clnt_vc_create()
that was waiting to a TCP connect to complete would return ERESTART,
since PCATCH was specified. Then the tsleep() in clnt_reconnect_call()
would sleep for 1 second and then try again and again and...
The patch changes the msleep() in clnt_vc_create() so it only sets
the PCATCH flag for interruptible cases.

4309e17add This patch changes head so that the default NFS client is now the new
NFS client (which I guess is no longer experimental). The fstype "newnfs"
is now "nfs" and the regular/old NFS client is now fstype "oldnfs".
Although mounts via fstype "nfs" will usually work without userland
changes, an updated mount_nfs(8) binary is needed for kernels built with
"options NFSCL" but not "options NFSCLIENT". Updated mount_nfs(8) and
mount(8) binaries are needed to do mounts for fstype "oldnfs".
The GENERIC kernel configs have been changed to use options
NFSCL and NFSD (the new client and server) instead of NFSCLIENT and NFSSERVER.
For kernels being used on diskless NFS root systems, "options NFSCL"
must be in the kernel config.

7126ba42f6 - Add the possibility to reuse the already last used timeout when patting
the watchdog, via the watchdog(9) interface.
  For that, the WD_LASTVAL bitwise operation is used. It is mutually
  exclusive with any explicit timout passing to the watchdogs.
  The last timeout can be returned via the wdog_kern_last_timeout()
  KPI.
- Add the possibility to pat the watchdogs installed via the watchdog(9)
  interface from the kernel.
  In order to do that the new KPI wdog_kern_pat() is offered and it does
  accept normalized nanoseconds or WD_LASTVAL.
- Avoid to pass WD_ACTIVE down in the watchdog handlers. All the control
  bit processing should over to the upper layer functions and not passed
  down to the handlers at all.

These changes are intended to be used in order to fix up the watchdog
tripping in situation when the userland is busted, but protection is still
wanted (examples: shutdown syncing / disk dumping).
