used by utilities to reset moused(8), for example. The syntax is:
!system=kern subsystem=power type=resume
Note that it would be nice to have notification of suspend, but it's more
difficult since there would have to be a method of doing request/ack
to userland and automatically timing out if no response. apm(4) has a
similar mechanism.

An executable contains at most one PT_INTERP program header. Therefore,
the loop that searches for it can terminate after it is found rather than
iterating over the entire set of program headers.
Eliminate an unneeded initialization.

prototypes, as the majority of new functions added have been in this
style. Changing prototype style now results in gcc noticing that the
implementation of vn_pollrecord() has a 'short' argument instead of
'int' as prototyped in vnode.h, so correct that definition. In practice
this didn't matter as only poll flags in the lower 16 bits are used.

Vararg functions have a different calling convention than regular
functions on amd64. Casting a varag function to a regular one to
match the function pointer declaration will hide the varargs from
the caller and we will end up with an incorrectly setup stack.
Entirely remove the varargs from these functions and change the
functions to match the declaration of the function pointers.
Remove the now unnecessary casts.
Lots of explanations and help from: peter

share devclass pointers, a mistake I've encouraged in the past) and
move the declaration of the pci_driver kobj class from cardbus.c to
pci_private.h so that other drivers can inherit from pci_driver.
devclass's parent pointer if the two drivers share the same devclass. This
can happen if the drivers use the same new-bus name. For example, we
currently have 3 drivers that use the name "pci": the generic PCI bus
driver, the ACPI PCI bus driver, and the OpenFirmware PCI bus driver. If
the ACPI PCI bus driver was defined as a subclass of the generic PCI bus
driver, then without this check the "pci" devclass would point to itself
as its parent and device_probe_child() would spin forever when it
encountered the first PCI device that did have a matching driver.

went away in the generated files? This didn't happen on my amd64
test machine but did when I committed it on my other i386 machine.
I need to figure this out since a regen on the amd64 doesn't fix it
now. For now make the build work again. Matt caught this before
my local mirror caught up.
This fixes reconnect after, for example, tcp idle disconnection.
Previously this would fail if a normal user tried to bind to a privileged
port.

errors from rn_inithead back to the ipfw initialization function.
- Check return value of rn_inithead for failure, if table allocation has
failed for any reason, free up any tables we have created and return ENOMEM
- In ipfw_init check the return value of init_tables and free up any mutexes or
UMA zones which may have been created.
- Assert that the supplied table is not NULL before attempting to dereference.
This fixes panics which were a result of invalid memory accesses due to failed
table allocation. This is an issue mainly because the R_Zalloc function is a
malloc(M_NOWAIT) wrapper, thus making it possible for allocations to fail.
