Mike Smith bb0d0a8efc Next phase in the PCI subsystem cleanup.
- Move PCI core code to dev/pci.
 - Split bridge code out into separate modules.
 - Remove the descriptive strings from the bridge drivers.  If you
   want to know what a device is, use pciconf.  Add support for
   broadly identifying devices based on class/subclass, and for
   parsing a preloaded device identification database so that if
   you want to waste the memory, you can identify *anything* we know
   about.
 - Remove machine-dependant code from the core PCI code.  APIC interrupt
   mapping is performed by shadowing the intline register in machine-
   dependant code.
 - Bring interrupt routing support to the Alpha
   (although many platforms don't yet support routing or mapping
   interrupts entirely correctly).  This resulted in spamming
   <sys/bus.h> into more places than it really should have gone.
 - Put sys/dev on the kernel/modules include path.  This avoids
   having to change *all* the pci*.h includes.

Some Alpha AXP OSF/1 binaries directly use the facilities provided by
the Mach kernel that is the basis for OSF/1.  These include (but are
surely not limited to) 'dd', 'ps', and 'w'.

Invariably, the symptom that these binaries display is that they crash
with an "unimplemented system call" trap (SIGSYS signal) for a syscall
that has a negative number.  In general, binaries that use the Mach
syscalls appear to invoke task_self() as their first syscall.

The name, number, and number of arguments for each Mach syscall is
given below; this information was gleaned by looking through the OSF/1
libmach.a's object files with dbx, then double-checked against the
contents of OSF/1's <mach/syscall_sw.h>.

These calls would be very difficult to implement properly in the
OSF/1 emulation code; by its very nature, NetBSD is not Mach, and we
don't and can't provide the underlying facilities that it does.
