macro for use when parsing MADT tables, thus we always tried to set the
interrupt model to APIC. This proved to be harmful on UP machines with
IO APIC's (or for UP kernels on SMP machines) since the wrong interrupt
routing information would be returned.

These makefiles work when building in the sys/modules directory, but
not with the objdir stuff that buildkernel uses. This is because they
used -I../../../blah rather than -I${.CURDIR}/../../../blah.

in struct proc. While the process label is actually stored in the
struct ucred pointed to by p_ucred, there is a need for transient
storage that may be used when asynchronous (deferred) updates need to
be performed on the "real" label for locking reasons. Unlike other
label storage, this label has no locking semantics, relying on policies
to provide their own protection for the label contents, meaning that
a policy leaf mutex may be used, avoiding lock order issues. This
permits policies that act based on historical process behavior (such
as audit policies, the MAC Framework port of LOMAC, etc) can update
process properties even when many existing locks are held without
violating the lock order. No currently committed policies implement use
of this label storage.

In this case, the system will mark the buffer as dirty again so
that the write can be retried in the future. When the write
succeeds or the system gives up on the buffer and marks it as
invalid (B_INVAL), the dependencies will be cleared.

Note: For efficiency, pmap_changebit() should be replaced by a function
similar to sparc64's pmap_clear_write().
