the proc lock only if we actually need to perform a stop. This
avoids two locks and unlocks of the process lock each system call,
and wins me about 20% on a simply system call test (getuid(),
which would otherwise require no locking). This also has a net
improvement of about 10MB/s on some of the SMP bandwidth tests
I'm running.

- malloc() returns a void* and does not need a cast
- when called with M_WAITOK, malloc() can not return NULL so don't
check for that case. The result of the check was bogus anyway since
it would leave the interface broken.

by its old name first, and log a warning (but accept the setting) if it
was found. If both the old and new name are defined, the new name takes
precedence.
Also export vm.kmem_size as a read-only sysctl variable; I find it hard to
tune a parameter when I don't know its default value, especially when that
default value is computed at boot time.
kbd_attach() is called kbd[0-9]+, with a different unit number. This
makes it impossible to write a devd rule which will automatically
switch to a USB keyboard when one is attached, because there is no way
to guess the correct device node to pass to kbdcontrol.
Therefore, change kbd_attach() to create a device node using the
keyboard device's real name (atkbd0, ukbd0...), and create the
kbd[0-9]+ node as an alias for backward compatibility.

Also, avoid trying to set NDIS_80211_AUTHMODE_AUTO since the Microsoft

and NdisCancelTimer(). NdisInitializeTimer() doesn't accept an NDIS
miniport context argument, so we have to derive it from the timer
function context (which is supposed to be the adapter private context).
NdisCancelTimer is now an alias for NdisMCancelTimer().
Also add stubs for NdisMRegisterDevice() and NdisMDeregisterDevice().
These are no-ops for now, but will likely get fleshed in once I start

can look at the ACPI tables. If the startup fails, we panic and tell the
user to try rebooting with ACPI disabled. Previously in this case we
would try to use $PIR interrupt routing which only works for the atpic
while using the apic to handle interrupts which would result in misrouted
interrupts and a hang at boot time with no error message.
- Read the SCI out of the FADT instead of hardcoding 9 when checking to see
if an interrupt override entry is for the SCI.
- Try to work around some BIOS brain damage for the SCI's programming by
forcing the SCI to be level triggered and active low if it is routed
to a non-ISA interrupt (greater than 15) or if it is identity mapped with
edge trigger and active high polarity. This should fix some of the hangs
with device apic and ACPI that some people see.

problem here still to be solved: the sockaddr_hci has still a 16 byte
field for the node name. The code currently does not correctly use the
length field in the sockaddr to handle the address length, so
node names get truncated to 15 characters when put into a sockaddr_hci.
