IRQ for an entry in a PCIBIOS interrupt routing ($PIR) table.
- Change pci_cfgintr() to except the current IRQ of a device as a fourth
argument and to use that IRQ for the device if it is valid.
- If an intpin entry in a $PIR entry has a link of 0, it means that that
intpin isn't connected to anything that can trigger an interrupt. Thus,
test the link against 0 to find invalid entries in the table instead of
implicitly relying on the irqs field to be zero. In the machines I have
looked at, intpin entries with a link of 0 often have the bits for all
possible interrupts for PCI devices set.
any machine dependent initialization. This allows the MD code to set the
interrupt routing model so that PCI interrupts are routed correctly when
using an APIC or SAPIC for example.
ev6 or pca56 etc this downgrades the cpu specification passed to gas.
As a result, gas will fail when gcc generates media instructions (in
uipc_usrreq.c). This only affects what gas will accept, not what gcc
generates or what our *.s file contain.
The process allocator now caches and hands out complete process structures
*including substructures* .
i.e. it get's the process structure with the first thread (and soon KSE)
already allocated and attached, all in one hit.
For the average non threaded program (non KSE that is) the allocated thread and its stack remain attached to the process, even when the process is
unused and in the process cache. This saves having to allocate and attach it
later, effectively bringing us (hopefully) close to the efficiency
of pre-KSE systems where these were a single structure.

Together these two implement a simple transcation style grouping for
modifications of extended attributes on a vnode.
VOP_CLOSEEXTATTR() takes a boolean "commit" argument, which determines
if the aggregate changes are attempted written or not. A commit will
fail if any of the VOP_SETEXTATTR() calls since the VOP_OPENEXTATTR()
have failed to meet their objective or if the flush to disk fails.
The default operations for these two VOP's is to return EOPNOTSUPP.
This API may still be subject to change.

- use `struct uma_zone *' instead of uma_zone_t, so that <sys/uma.h> isn't
a prerequisite.
- don't include <sys/uma.h>.
Namespace pollution makes "opaque" types like uma_zone_t perfectly
non-opaque. Such types should never be used (see style(9)).
Fixed subsequently grwon dependencies of this header on its own pollution:
- include <sys/_mutex.h> and its prerequisite <sys/_lock.h> instead of
depending on namespace pollution 2 layers deep in <sys/uma.h>.
not the 'entry' member. The entry point is formed from both a base and
a relative entry point. 'entry' is that relative offset. It is perfectly
valid to have an entry point with a relative offset of 0. PCIbios.ventry
is the virtual address of the entry point that takes both 'base' and
'entry' into account, thus it is the proper variable to test to see if we
have an entry point or not.
lnc(4) will attach to AMD PCnet/FAST NICs if pcn(4) does not attach.
I.e. pcn(4) gets first chance. There is a problem however in that pcn(4)
was moved out of the install kernel so that the module would be used.
This however causes bad installs if one has an AMD PCnet/FAST NIC.

Include <sys/vmmeter.h> instead of depending on namespace pollution in
<sys/pcpu.h>.
Sorted includes as much as possible.

Fix abbreviation for P_STOPPED_* etc flags, in original code they were
inconsistent and difficult to distinguish between them.

Removed unused includes.
Fixed some printf format errors (1 fatal on i386's; 1 fatal on alphas;
1 not fatal on any supported machine).
