Each AMD Geode MFGPT timer interrupt output is paired with another
timer; esentially the interrupt goes if either timer fires.  This
is okay, but the handlers need to be aware of this.  Make sure in
the timer tick handler that our timer really did expire.

We *really* don't want to be reading MFGPTx_SETUP and writing back those
values.  What we want to be doing is clearing CMP1 and CMP2 unconditionally;
otherwise, we have races where CMP1 and/or CMP2 fire after we've read
MFGPTx_SETUP.  They can also fire between when we've written ~CNTEN to
the register, and when the new register values get copied to the timer's
version of the register.  By clearing both fields, we're okay.

There isn't much value to always detecting the MFGPT timers on

We had planned to use the 'owner' field for allowing re-allocation of

drop this for now.  If it turns out that we need timers in modules, we'll
need to come up with a scheme that matches the write-once fields of the
MFGPTx_SETUP register, and drops ponies from the sky.

The GEODE MFGPT code assumed that 32kHz was 32000 Hz while the boards
run on a 32.768 kHz digital watch crystal. In practise, it will not
change the timer's frequency as the skew was only 2.4%, but it
should provide more accurate intervals.

mm_cgroup() is exclusively used to test whether an mm's mem_cgroup pointer
is pointing to a specific cgroup.  Instead of returning the pointer, we can
just do the test itself in a new macro:

	vm_match_cgroup(mm, cgroup)

returns non-zero if the mm's mem_cgroup points to cgroup.  Otherwise it
returns zero.

Does it ever make sense to ask "is this pte a swap entry?" on a machine
with no MMU?  Presumably this also means it has no ptes too, right?  In
which case, it's better to comment the whole function out.  Then when
someone tries to ask the above meaningless question, they get a compile

Add support for different number of page table levels dependent
on the highest address used for a process. This will cause a 31 bit
process to use a two level page table instead of the four level page
table that is the default after the pud has been introduced. Likewise
a normal 64 bit process will use three levels instead of four. Only
if a process runs out of the 4 tera bytes which can be addressed with
a three level page table the fourth level is dynamically added. Then
the process can use up to 8 peta byte.

There are two problems in the vt220 intialization:

o Currently the vt220 console looses early printk events until the
  the vt220 tty is registered.
o console should work if tty_register fails

sclp_vt220_con_init calls __sclp_vt220_init and register_console.
It does not register the driver with the sclp core code via
sclp_register. That results in an sclp_send_mask=0. Therefore,
__sclp_vt220_emit will reject buffers with EIO. Unfortunately
register_console will cause the printk buffer to be sent to the
console and, therefore, every early message gets dropped. The
sclp_send_mask is set later during boot, when sclp_vt220_tty_init
calls sclp_register.

The solution is to move the sclp_register call from sclp_vt220_tty_init
to __sclp_vt220_init. This makes sure that the console is properly
registered with the sclp subsystem before the first log buffer messages
are passed to the vt220 console.

We also adopt the cleanup on error to keep the console alive if
tty_register fails.

Thanks to Peter Oberparleiter and Heiko Carstens for review and ideas
for improvement.
