d331c5d43f Replace the global buffer hash table with per-vnode splay trees using a
methodology similar to the vm_map_entry splay and the VM splay that Alan
Cox is working on.  Extensive testing has appeared to have shown no
increase in overhead.

Disadvantages
    Dirties more cache lines during lookups.

    Not as fast as a hash table lookup (but still N log N and optimal
    when there is locality of reference).

Advantages
    vnode->v_dirtyblkhd is now perfectly sorted, making fsync/sync/filesystem
    syncer operate more efficiently.

    I get to rip out all the old hacks (some of which were mine) that tried
    to keep the v_dirtyblkhd tailq sorted.

    The per-vnode splay tree should be easier to lock / SMPng pushdown on
    vnodes will be easier.

    This commit along with another that Alan is working on for the VM page
    global hash table will allow me to implement ranged fsync(), optimize
    server-side nfs commit rpcs, and implement partial syncs by the
    filesystem syncer (aka filesystem syncer would detect that someone is
    trying to get the vnode lock, remembers its place, and skip to the
    next vnode).

Note that the buffer cache splay is somewhat more complex then other splays
due to special handling of background bitmap writes (multiple buffers with
the same lblkno in the same vnode), and B_INVAL discontinuities between the
old hash table and the existence of the buffer on the v_cleanblkhd list.

ad22735e3f Don't slow every syscall and trap by doing locks and stuff if the
'stop' bits are not set. This is a temporary thing.. I think this code probably
needs to be rewritten anyhow.

832dafad3d Rearrange the code so that it checks whether the file is something
valid to write a core dump to before doing the preparations to actually
write to the file.

Call VOP_GETATTR() before dropping the initial vnode lock.

5287ec6ef0 Fixed compiling with -D_POSIX_SOURCE. The previous commit was supposed to
fix this, but actually broke it a little differently by adding 2 invalid
references to struct timespec while fixing 1.

ce907d4246 Add a VT_LOCKSWITCH ioctl that disallows vty switching. Something
like this can be emulated by VT_SETMODEing to VT_PROCESS and never
releasing the vty, but this has a number of problems, most notably
that a process must stay resident for the lock to be in effect.

f55348f07c Include all of isa/ipl.s into exception.s as there is now nothing left in
ipl.s except doreti which really belongs in with the exceptions as it's
just the other side of the same coin. Will remove ipl.s in a separate commit.
