newbus for referencing device interrupt handlers.
- Move the 'struct intrec' type which describes interrupt sources into
sys/interrupt.h instead of making it just be a x86 structure.
- Don't create 'ithd' and 'intrec' typedefs, instead, just use 'struct ithd'
and 'struct intrec'
- Move the code to translate new-bus interrupt flags into an interrupt thread
priority out of the x86 nexus code and into a MI ithread_priority()
function in sys/kern/kern_intr.c.
- Remove now-uneeded x86-specific headers from sys/dev/ata/ata-all.c and
sys/pci/pci_compat.c.
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot). This is consistant with the other
BSD's who made this change quite some time ago. More commits to come.
Interrupts under the new scheme are managed by the i386 nexus with the
awareness of the resource manager. There is further room for optimizing
the interfaces still. All the users of register_intr()/intr_create()
should be gone, with the exception of pcic and i386/isa/clock.c.
- created internal names for fixed-size integral types, like __int32_t. They
will be used to make several headers self-sufficient.
- <stdlib.h> don't include <machine/types.h> anymore.
- created <sys/inttypes.h>, which can be used as <inttypes.h>.
- declaration of uoff_t and ufs_daddr_t moved to <sys/types.h>.

least unsuitable for holding an object pointer. This should have been
used to fix warnings about casts between pointers and ints on alphas.
Moved corresponding existing general typedef (fptrint_t) for function
pointers from the i386 <machine/profile.h> to a kernel-only typedef
in <machine/types.h>. Kludged libc/gmon/mcount.c so that it can
still see this typedef.

Define an unsigned version of off_t (uoff_t) if KERNEL is defined.
This is useful for micro-optimizing expressions involving off_t's

doesn't know it.
Fixed a gratuitous ANSIism.

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
The main change is from unsigned long unsigned int. It just needs to
be a 32-bit type and unsigned int is most natural. Using a non-long
type has the "advantage" of hiding bugs in the "machine-independent"
code where it prints foo_t's using %d or %x. These bugs are currently
hidden bug not compiling with -Wformat.
I tried changing vm_ooffset_t from long long to unsigned long long, but
that was wrong because vm_ooffset_t needs to be long to match off_t,
although file offsets are never negative.
