7aa6584632 o Fixes:
- When switching to 4-bit operation, send a SET_CLR_CARD_DETECT command
    to disconnect the card-detect pull-up resistor from the DAT3 line before
    sending the SET_BUS_WIDTH command.
  - Add the missing "reserved" zero entry to the mantissa table used to
    decode various CSD fields. This was causing SD cards to report that they
    could run at 30 MHz instead of the maximum 25 MHz mandated in the spec.
o Enhancements:
  - At the MMC layer, format various info from the CID into a string that
    uniquely identifies the card instance (manufacturer number, serial
    number, product name and revision, etc). Export it as an instance
    variable.
  - At the MMCSD layer, display the formatted card ID string, and also
    report the clock speed of the hardware (not the card's max speed), and
    the number of bits and number of blocks per transfer. It comes out like
    this now:
    mmcsd0: 968MB <SD SD01G 8.0 SN 276886905 MFG 08/2008 by 3 SD> at mmc0
    22.5MHz/4bit/128-block

a511762672 Fix the following compilation warnings in sys/contrib/rdma/rdma_cma.c:

  #define ECONNREFUSED    61              /* Connection refused */
		      ^

This is because the switch uses iw_cm_event::status, which is an enum
iw_cm_event_status, while ECONNRESET, ETIMEDOUT and ECONNREFUSED are
just plain defines from errno.h.

It looks like there is only one use of any of the enumeration values of
iw_cm_event_status, in:

  sys/contrib/rdma/rdma_iwcm.c: 	if (iw_event->status == IW_CM_EVENT_STATUS_ACCEPTED) {

So messing around with the enum definitions to fix the warning seems too
disruptive; the simplest fix is to cast the argument of the switch to
int.

enum xge_event_e.

ce4857d146 The amr(4) firmware contains a rather dubious "feature" where it
assumes for small buffers (< 64k) that the OS driver is actually using
a buffer rounded up to the next power of 2.  It also assumes that the
buffer is at least 4k in size.  Furthermore, there is at least one
known instance of megarc sending a request with a 12k buffer where the
firmware writes out a 24k-ish reply.

To workaround the data corruption triggered by this "feature", ensure
that buffers for user commands use a minimum size of 32k, and that
buffers between 32k and 64k use a 64k buffer.

There is such a thing as a 64-bit EFI application, but it's not

we can load and actualy boot a kernel) before solving the 64-bit

b50d8083ab Introduce the matching PCI ath(4) fixup code from ar71xx_pci into
ar724x_pci.c.

* Move out the code which populates the firmware into ar71xx_fixup.c
* Shuffle around the ar724x fixup code to match what the ar71xx fixup
  code does.

I've validated this on an AR7240 with AR9285 on-board NIC. It doesn't
yet load, as the AR9285 EEPROM code needs to be made "flash aware."

TODO:

* Validate that I haven't broken AR71xx
* Test AR9285/AR9287 onboard NICs, complete with EEPROM code changes
* Port over the needed BAR hacks for AR7240, AR7241 and AR7242 from
  Linux OpenWRT.  The current WAR has only been tested on the AR7240
  and I'm not sure the way the BAR register is treated is "right".
  The "fixup" method here is right when setting the BAR for local access -
  ie, the BAR address is either 0xffff (AR7240) or 0x1000ffff (AR7241/AR7242),
  but the ath9k-fixup.c code (Linux OpenWRT) does this when setting the
  initial "fixup" BAR.  It then restores the original BAR.
  I'll have to read the ar724x PCI bus glue to see what other special cases
  await.

dca5e0ec50 This update uses the MNT_VNODE_FOREACH_ACTIVE interface that loops
over just the active vnodes associated with a mount point to replace
MNT_VNODE_FOREACH_ALL in the vfs_msync, ffs_sync_lazy, and qsync
routines.

The vfs_msync routine is run every 30 seconds for every writably
mounted filesystem. It ensures that any files mmap'ed from the
filesystem with modified pages have those pages queued to be
written back to the file from which they are mapped.

The ffs_lazy_sync and qsync routines are run every 30 seconds for
every writably mounted UFS/FFS filesystem. The ffs_lazy_sync routine
ensures that any files that have been accessed in the previous
30 seconds have had their access times queued for updating in the
filesystem. The qsync routine ensures that any files with modified
quotas have those quotas queued to be written back to their
associated quota file.

In a system configured with 250,000 vnodes, less than 1000 are
typically active at any point in time. Prior to this change all
250,000 vnodes would be locked and inspected twice every minute
by the syncer. For UFS/FFS filesystems they would be locked and
inspected six times every minute (twice by each of these three
routines since each of these routines does its own pass over the
vnodes associated with a mount point). With this change the syncer
now locks and inspects only the tiny set of vnodes that are active.

f257ebbb2e This change creates a new list of active vnodes associated with
a mount point. Active vnodes are those with a non-zero use or hold
count, e.g., those vnodes that are not on the free list. Note that
this list is in addition to the list of all the vnodes associated
with a mount point.

To avoid adding another set of linkage pointers to the vnode
structure, the active list uses the existing linkage pointers
used by the free list (previously named v_freelist, now renamed
v_actfreelist).

This update adds the MNT_VNODE_FOREACH_ACTIVE interface that loops
over just the active vnodes associated with a mount point (typically
less than 1% of the vnodes associated with the mount point).

a47f39da1f Stop using the hardware register value byte order swapping for now,
at least until I can root cause what's going on.

The only platform I've seen this on is the AR9220 when attached to
the AR71xx CPUs.  I get immediate PCIe bus errors and all subsequent
accesses cause further MIPS bus exceptions.  I don't have any other
big-endian platforms to test this on.

If I get a chance (or two), I'll try to whack this on a bus analyser
and see exactly what happens.

I'd rather leave this on, especially for slower, embedded platforms.
But the #ifdef hell is something I'm trying to avoid.

 - Implement Active/Read mode as hybrid of Active/Active and Active/Passive.
In this mode all paths not marked FAIL may handle reads same time,
but unlike Active/Active only one path handles write requests at any
point in time. It allows to closer follow original write request order
if above layers need it for data consistency (not waiting for requisite
write completion before sending dependent write).

The Clang compiler already inlines these functions, so they do not

set their frame in kgdb which means that it is impossible to view

71469bb38f Replace the MNT_VNODE_FOREACH interface with MNT_VNODE_FOREACH_ALL.
The primary changes are that the user of the interface no longer
needs to manage the mount-mutex locking and that the vnode that
is returned has its mutex locked (thus avoiding the need to check
to see if its is DOOMED or other possible end of life senarios).

To minimize compatibility issues for third-party developers, the
old MNT_VNODE_FOREACH interface will remain available so that this
change can be MFC'ed to 9. Following the MFC to 9, MNT_VNODE_FOREACH
will be removed in head.

The reason for this update is to prepare for the addition of the
MNT_VNODE_FOREACH_ACTIVE interface that will loop over just the
active vnodes associated with a mount point (typically less than
1% of the vnodes associated with the mount point).
