standard in C99 and POSIX.1-2001+. They are also not deprecated, since
apart from being standard they can handle special args slightly better
than the ilogb() functions.
Move their documentation to ilogb.3. Try to use consistent and improved
wording for both sets of functions. All of ieee854, C99 and POSIX
have better wording and more details for special args.
Add history for the logb() functions and ilogbl(). Fix history for
ilogb().
this by accessing the cdev_priv element of the cdev structure. Looking
forward we need a better way to handle this, as this structure shouldn't
be frobbed by userspace.

will improve hardware support.

from there. All others get broken up and free'd individually to the mbuf
and cluster zones.
The packet zone is a secondary zone to the mbuf zone. There is currently
a limitation in UMA which prevents decreasing the packet zone stock when
the mbuf and cluster zone are drained and all their members are part of
packets. When this is fixed this change may be reverted.
- Fix a typo in rsmisc.c and a style change for consistency.
This patch will also appear in future ACPI-CA release.

Previously, pvzone's initialization was split between pmap_init() and
pmap_init2(). This split initialization was the underlying cause of
some UMA panics during initialization. Specifically, if the UMA boot
pages was exhausted before the pvzone was fully initialized, then UMA,
through no fault of its own, would use an inappropriate back-end
allocator leading to a panic. (Previously, as a workaround, we have
increased the UMA boot pages.) Fortunately, there is no longer any
reason that pvzone's initialization cannot be completed in
pmap_init().
Eliminate a check for whether pv_entry_high_water has been initialized
or not from get_pv_entry(). Since pvzone's initialization is
completed in pmap_init(), this check is no longer needed.
Use cnt.v_page_count, the actual count of available physical pages,
instead of vm_page_array_size to compute the maximum number of pv
entries.
Introduce the vm.pmap.pv_entries tunable on alpha and ia64.
Eliminate some unnecessary white space.

a synchronous reprogramming of hardware MAC filters if the physical
interface are up and running. Previously, MAC filters would be
reconfigured only when the fec interface was brought up.
- Disallow bundle reconfiguration when virtual
interface is running; otherwise, removing a
port from a running configuration will cause
a panic in the start() method on the next packet
on an assumption that a bundle has an even
number of ports (2 or 4).
- Disallow bringing of virtual interface to a
running state when a bundle size is 0; otherwise,
adding and then removing the port will similarly
cause a panic.
- Add missing initialization of fec_ifstat when
adding a new port and fix media status reporting
when virtual interface isn't yet up (check for
fec_status of 1 rather than != 0).
previously, ifp->if_type was set to IFT_ETHER by
ether_ifattach(), now it's done by if_alloc() so
an assignment of if_type to IFT_PROPVIRTUAL after
if_alloc() but before ether_ifattach() broke it.
This makes arp(8) and friends happy about the fec
interfaces, and will allow us to use if_setlladdr()
on the fec interface.
- Set/reset IFF_DRV_RUNNING/IFF_DRV_OACTIVE in init()
and stop() methods rather than in ioctl(), like the
rest of the drivers do. This fixes a bug when an
"ifconfig fec0 ipv4_address" would not have made
the interface running, didn't launch the ticker
function to track media status of bundled ports,
etc.

I'm not very fond of using the non-standard lockf(1) here, but I
have no better idea at the moment. NetBSD uses ln(1) to create a
lock file, but this approach can result in a deadlock if make is
interrupted, leaving an orphaned lock file.
buffers *and* there are no buffers queued up for writing. The bug
was that NMODIFIED was being cleared even while there were buffers
scheduled to be written out, which leads to all sorts of interesting
bugs - one where the file could shrink (because of a post-op getattr
load, say) causing data in buffer(s) queued for write to be tossed,
resulting in data corruption.
