We must force payload alignment to a longword boundary to make the
alpha happy. This should stop the driver from trapping on the alpha
when the interface is ifconfig'ed (actually, when the first frame is
received).
USB WebCams, using a patch from Peter Housel.
With this change ugen, and with Peter's 'vid' program
in ports/graphics/vid, we can capture single images from USB Cameras
using the OmniVision OV511 chipset (including some models of the
Creative WebCam 3)
NetBSD merged in Peter's patch to their ugen.c file
several months ago, so this brings us back in line.

Change a few indentations to tabs.
Change the functions to use ANSI sytle parameters.
This lowers the diffs between our copy of ugen.c and NetBSD's copy

This commit adds support for proper PCI interrupt mapping and much
better support for swizzling between "standard" isa IRQs and the stdio
irqs used by the t2. This also adds enabling/disabling/eoi support
for AlphaServer 2100A machines. The 2100A (or lynx) interrupt
hardware is is very different (and much nicer) than the 2100.
Previously, only AS2100 and AS2000 machines worked.
This commits also lays the groundwork for supporting ExtIO modules.
These modules are essentially a second hose. This work is left
unfinished pending testing on real hardware. Wilko tells me that
ExtIO modules are quite rare, and may not actually exist in the wild.

Backout the previous delta (rev 1.4), it didn't make any difference.
If the requested handle is NULL then don't add it to the list of
objects, to be found by handle.
The problem is that when asking for a NULL handle you are implying
you want a new object. Because objects with NULL handles were
being added to the list, any further requests for phys backed
objects with NULL handles would return a reference to the initial
NULL handle object after finding it on the list.
Basically one couldn't have more than one phys backed object without
a handle in the entire system without this fix. If you did more
than one shared memory allocation using the phys pager it would
give you your initial allocation again.
Deal with excessive dirty buffers when msync() syncs non-contiguous
dirty buffers by checking for the case in UFS *before* checking for
clusterability.
__P() prototypes when an ansi-style static inline is a prototype already.
Since vnode_if.[ch] are generated on the fly, there are no CVS diffs to
mess up.
SMP problem. Compaq, in their infinite wisdom, forgot to put the IO apic
intpin #0 connection to the 8259 PIC into the mptable. This hack is to
look and see if intpin #0 has *no* table entry and adds a fake ExtInt
entry for the remap routines to use. isa/clock.c will still test the
interrupts. This entry is only ever used on an already broken system.
where fork1() could put the process on the run queue where it could be
snatched up by another CPU before kthread_create() had set the proper
fork handler. Instead, we put the new kthread on the runqueue after its
fork handler has been sent.

mutex operations. In the future they may call functions that verify
correct locking order between processes in the INVARIANTS case.
- Lock the process in PHOLD() and PREL().
mpapic.c. This gives us the benefit of C type checking. These functions
are not called in any critical paths and are not used by the interrupt
routines.
place the LOCKing macros within the areas within if_wxvar.h that
is set aside for them. Put any platform specific data also in those
areas.
For ease of maintenance purposes, merge in the OpenBSD version codebase here.
- Whitespace fixes.
- Comment fixes (mostly capitalization and trailing periods).
- Reorderings to put variables all in the same place, function prototypes
sorted alphabetically, etc.
2. Removed unused and #ifdef'd out members from struct ithd.
3. Changed ESTCPULIM() to use an explicit (PRIO_MAX - PRIO_MIN) rather than
PRIO_TOTAL.
4. Remove <sys/lock.h> #include and resort #include's.

a tunstart function, which is called when a packet is sucessfully
placed on the queue. This allows us to properly do output byte accounting
within the handoff routine.
Add a test against isp->isp_osinfo.islocked prior to trying to see
whether --isp->isp_osinfo.islocked is zero to cause us to unlock
(non-SMPLOCK case).
