f74fae21b8 Add support for userland to access I/O port space. This is primarily 
added for XFree86. There are 2 reasons for doing this with sysarch():
1. The memory mapped I/O space is not at a fixed physical address. An
   application has to use some interface to get the base address. It
   gets worse if the machine has multiple memory mapped I/O spaces.
2. Access to the memory mapped I/O space needs to happen through a
   translation that is flagged as uncachable. There's no interface
   that allows a process to do uncached memory I/O, other than though
   /dev/mem (possibly).

So, until we either disallow direct access to I/O or bus space from
userland or have a better way of doing this, sysarch() has the least
negative impact on existing interfaces.

We have to put dcons_crom at first after 'optional' and
dcons and firewire are necessary and not optional for dcons_crom anyway.

f3075be88a For the SMP case, flush the TLB at the beginning of the page zero/copy 
routines.  Otherwise we run into trouble with speculative tlb preloads
on SMP systems.  This effectively defeats Jeff's revision 1.438
optimization (for his pentium4-M laptop) in the SMP case.  It breaks
other systems, particularly athlon-MP's.

36bbf86ba6 Check (locked) before performing an advisory unlock following a failure

c447f5b2f4 When generate a core dump, use advisory locking in an advisory way: 
if we do acquire an advisory lock, great!  We'll release it later.
However, if we fail to acquire a lock, we perform the coredump
anyway.  This problem became particularly visible with NFS after
the introduction of rpc.lockd: if the lock manager isn't running,
then locking calls will fail, aborting the core dump (resulting in
a zero-byte dump file).

da77b2fa6b Make MAC_EXTERNALIZE() and MAC_INTERNALIZE() simply take the object 
type, rather than "object_label" as the first argument.  This reduces
complexity a little for the consumer, and also makes it easier for
use to rename the underlying entry points in struct mac_policy_obj.
