was made in r199543 to remove MTX_RECURSE. These routines can be
called in device attach phase(e.g. mii_phy_probe()) so checking
assertion here is not right as caller does not hold a driver lock.
The information used by the "Last login:"-line is obtained by using
ulog_setutxfile(3) to switch to the lastlog database. Login and logout
are performed using the utility functions ulog_login(3) and
ulog_logout(3).
This also means we must build libulog during bootstrap.

The rewrite of the interrupt handler includes:
o loop until all pending interrupts are handled. This closes a
race condition.
o count the number of interrupt sources we handled so that we can
properly return FILTER_HANDLED or FILTER_STRAY when we break out
of the loop.
o When matching the interrupt source to the devices that have that
source pending, check only from the set of devices we found to
have a pending interrupt.

Take this one step further and model it on the existing NetBSD quirk and import

It turns out these entries do make Terminal.app behave a little better.
According to Thomas Dickey, Terminal.app should use TERM=nsterm anyway,
but we don't support this yet. Already having an improved termcap entry
helps, so I am going to MFC this change after all.

- cast the result of LEN() to int as this is the main usage.
- use LEN() in one place where it was forgotten.
- Document the use of a static variable in rw mode.

1) Avoid an infinite loop in the header resync for certain malformed
archives.
2) Don't try to match hardlinks if the nlinks count is < 2. This
reduces the likelihood of a false hardlink match due to ino truncation.

are not allocated by the device driver. These resources should still appear
allocated from the system's perspective so that their assigned ranges are
not reused by other resource requests. The PCI bus driver has used a hack
to effect this for a while now where it uses rman_set_device() to assign
devices to the PCI bus when they are first encountered and later assigns
them to the actual device when a driver allocates a BAR. A few downsides of
this approach is that it results in somewhat confusing devinfo -r output as
well as not being very easily portable to other bus drivers.
This commit adds generic support for "reserved" resources to the resource
list API used by many bus drivers to manage the resources of child devices.
A resource may be reserved via resource_list_reserve(). This will allocate
the resource from the bus' parent without activating it.
resource_list_alloc() recognizes an attempt to allocate a reserved resource.
When this happens it activates the resource (if requested) and then returns
the reserved resource. Similarly, when a reserved resource is released via
resource_list_release(), it is deactivated (if it is active) and the
resource is then marked reserved again, but is left allocated from the
bus' parent. To completely remove a reserved resource, a bus driver may
use resource_list_unreserve(). A bus driver may use resource_list_busy()
to determine if a reserved resource is allocated by a child device or if
it can be unreserved.
The PCI bus driver has been changed to use this framework instead of
abusing rman_set_device() to keep track of reserved vs allocated resources.

safely allocate a heap region above 1MB. This enables {gpt,}zfsboot()
to allocate much larger buffers than before.
- Use a larger buffer (1MB instead of 128K) for temporary ZFS buffers. This
allows more reliable reading of compressed files in a raidz/raidz2 pool.
