Missing <uaccess.h>

Missing <uaccess.h>

The idea is to move more to if(pc98) so that we can attempt to get all
the ports buildable as one "generic" port in time. I don't think its p
possible for PC9800 but no need to dig holes

Now hw resources can be per mach- and we dont need a pile of ugly
ifdefs for weird shite

Don't pass DEVFS_FL_CURRENT_OWNER to devfs_register, the uid/gid of new
nodes should always be 0.

Okay, all flags are gone from devfs callers, time to remove the gunk
handling it.  devfs_register prototype will change later.

This patch rips out handling of UNIX98 ptys from devfs.  We already
have a special small filesystem to handle it (devpts) that's always
compiled in anyway.  This allows to get rid of all DEVFS_FL* flags and
some gunk in devfs.

Trying to always have a NULL first argument to simplify devfs code
big time in mid-term.  (Especially in preparation of Adam's smalldevfs).

register a /dev/cpu/microcode symlink instead of a regular file
with the same name - regular file support is gone in devfs.

- Add driver registration for dv1394/video1394/raw1394.
- Fix 3 sleep-while-atomic bugs in ohci1394 and ieee1394.
- Cleanup some bus-reset handling in ohci1394.
- Add empty config-rom handling.
- Check and handle SBP-2 logins active/available for non-exclusive
  logins.
- Fix bug in SBP-2 DMA cleanup.

In the interests of SMP scalability the ext2 free blocks and free inodes
counters are "approximate".  But there is a piece of code in the Orlov
allocator which fails due to boundary conditions on really small
filesystems.

Fix that up via a final allocation pass which simply uses first-fit for
allocation of a directory inode.

My recent micro-optmisation to these functions broke the pfn_valid()
checks.  Revert it.

This BUG_ON is triggering via ppp's line discipline flushing, due to
brokenness in tty_io.c.

We need to fix tty.  Meanwhile, let's not gratuitously nuke people's boxes.
