2d46b036a0 Enable 4-byte address support for the mx25l family of SPI flash devices.
Introduce 2 new flags:
- FL_ENABLE_4B_ADDR (forces the use of 4-byte addresses)
- FL_DISABLE_4B_ADDR (forces the use of 3-byte addresses)

If an SPI flash chip is defined with FL_ENABLE_4B_ADDR in its flags,
then an 'Enter 4-byte mode' command is sent to the chip at attach time
and, later, all commands that require addressing are issued with 4-byte
addresses.
If an SPI flash chip is defined with FL_DISABLE_4B_ADDR in its flags,
then an 'Exit 4-byte mode' command is sent to the chip at attach time
and, later, all commands that require addressing are issued with 3-byte
addresses.
For chips that do not have any of these flags defined the behaviour is
unchanged.

This change also adds support for the MX25L25735F and MX25L25635E chips
(vendor id 0xc2, device id 0x2019), which support 4-byte mode and enables
4-byte mode for them. These are 256Mbit devices (32MiB) and, as such, can
only be fully addressed by using 4-byte addresses.

This change should not be MFCed until new collate will be

598003be2d [iwn] Don't try to seamlessly recover from a firmware panic; just restart
the interface.

I know this may be unpopular, but iwn is not yet completely ready for
a transparent firmware restart.  I have this thing panic my laptop
reliably because 11n state isn't kept in sync and the TX completion
path ends up trying to free a null node reference.

e881d8757c remove emulation of VFS_HOLD and VFS_RELE from opensolaris compat
On FreeBSD VFS_HOLD/VN_RELE were mapped to MNT_REF/MNT_REL that
manipulate mnt_ref.  But the job of properly maintaining the reference
count is already automatically performed by insmntque(9) and
delmntque(9).  So, in effect all ZFS vnodes referenced the corresponding
mountpoint twice.

That was completely harmless, but we want to be very explicit about what
FreeBSD VFS APIs are used, because illumos VFS_HOLD and FreeBSD MNT_REF
provide quite different guarantees with respect to the held vfs_t /
mountpoint.  On illumos VFS_HOLD is sufficient to guarantee that
vfs_t.vfs_data stays valid.  On the other hand, on FreeBSD MNT_REF does
*not* provide the same guarantee about mnt_data.  We have to use
vfs_busy() to get that guarantee.

Thus, the calls to VFS_HOLD/VFS_RELE on vnode init and fini are removed.
VFS_HOLD calls are replaced with vfs_busy in the ioctl handlers.

And because vfs_busy has a richer interface that can not be dumbed down
in all cases it's better to explicitly use it rather than trying to mask
it behind VFS_HOLD.

This change fixes a panic that could result from a race between
zfs_umount() and zfs_ioc_rollback().  We observed a case where
zfsvfs_free() tried to destroy data that zfsvfs_teardown() was still
using.  That happened because there was nothing to prevent unmounting of
a ZFS filesystem that was in between zfs_suspend_fs() and
zfs_resume_fs().

c36c6e72c6 Various updates to the PCI-express capability output.
- Group the output so that it follows the capability register set more
  closely.  The first line now contains device information and the
  second line contains link information.  As a result, ARI status is now
  output on the first line, and the link width is moved down to the second
  line of link information.
- Only read the DEVICE_CAP2 register to check for ARI if the capability
  version is >= 2.
- Don't output any link information if the link capability and status
  registers are zero.
- Label the MSI interrupt index value as "MSI" instead of "IRQ".
