This changes the F00F bug workaround code to use the fixmap facilities
instead of touching the page tables directly.  It also removes the
assumption that only 686's don't have the bug.  I have confirmation that
the patch works on buggy pentiums. 

It needs the following patch

	In case if proc_pid_make_inode() steps on exiting task we do
iput() and return NULL.  Unfortunately, in that case inode->i_ino
doesn't look like inumber of a per-process inode and we take the
wrong path in proc_delete_inode().  I.e. do dput(PDE(inode)).  Which
is left uninitialized...

	We used to get out with that almost by accident - that code
worked only because we had zeroed out one field of union and that
guaranteed that another field would be NULL.  It worked, but broke
at the first occasion.

* introduces a new filesystem - nfsd.  No, it's not a typo.  It's a small
  tree with fixed topology defined by nfsd and IO on its files does what
  we used to do by hand in nfsctl.c.
* turns sys_nfsservctl() into a sequence of open()/write()/read()/close()
  It works as it used to - we don't need nfsd to be mounted anywhere, etc.
* nfsd_linkage ugliness is gone.
* getfs and getfh demonstrate (rather trivial) example of "descriptor as
  transaction descriptor" behaviour.
* we are fairly close to the situation when driver-defined filesystems can
  be done with practically zero code overhead.  We are still not there, but
  it's a matter of adding a couple of helpers for populating the tree.

	One thing we get immediately is a cleanup of sys_nfsservctl() -
it got _much_ better.  Moreover, we get an alternative interface that
uses normal file IO and can be used without magic syscalls.

Several exits in exp_export() forget to call path_release().  Fixed.

	Linus, I've taken a bunch of common methods into fs/libfs.c and
killed the (duplicated) instances in filesystems.  There will be more -
ideally I'd like to get a library that would make writing small filesystems
trivial.

As mentioned on May 11 on LKML, here is a patch to fix /proc/kcore for
architectures which do not have RAM located at physical address 0.

The following patch removes Alt-Sysrq-L and its associated hack to kill
of PID1, the init process.  This is a mis-feature.

If PID1 is killed, the kernel immediately enters an infinite loop in the
depths of do_exit() with interrupts disabled, completely locking the
machine.  Obviously you can only reach for the reset button or power
switch after this, leaving you with dirty filesystems.

There is a problem where the resource flags sometimes contain bits from
the address part of the PCI BAR, especially when you have the low address
bit set for an IO BAR.

(bit 3 of a PCI IO BAR is an address bit, and (bar & 0xf) propagates this
to res->flags).

This exists in Ivan Kokshaysky PCI patches, and so far hasn't made it into
the kernel.  It's required for IDE on certain ARM machines to even work.

This patch actually fixes the starvation bug in sys_wait4() by moving any
process which is serviced for stoppage to the end of the child list.

This patch (#1) just converts the task_struct to use struct list_head rather
than direct pointers for maintaining the children list.

Current behavior is not changed at all, but see the next cset for what
it's good for.

- switch to yield function as suggested by you, Arjan and Andrew.
- fixed broken logic in the use of time_before/time_after - possible
bug cause in previous design - in most of the places we were going to sleep
and than check if time expires before checking if condition is satisfied.
If, for example, we needed to wait up to 3 jiffies we could do
schedule_timeout(1) and get up after 4 ticks check that time expired and go
away crying about failure without checking that condition is OK.(in fact I
saw it happen on one SMP platform here).

- added pci flushing in the e100_set_intr_mask function (pci posting bug)
- better logic in the prepare_xmit_buff function moving some tx
buffer initialization code to the start of the function.

- remove dummy defines and also ia64 specific [Arjan's notes  [:-)] ]
- fixed problem in e100_check_options function reported by our Q/A

- minor changes to the license from our technical writer [still GPL ;-)]
