[IA64] fix ia64 Kconfig to allow CONFIG_PM on sn2

This probably should have been fixed when I fixed up the generic build for
discontig+numa machines, but oh well.

CONFIG_PM is allowable for generic builds but not for sn2 builds, which
doesn't make much sense, and in fact breaks the build if recent ACPI bits are
added to the tree.  It looks like the only arch that needs to prevent
CONFIG_PM stuff is the ski simulator (though those options could probably use
some cleanup as well), so remove the big conditional and replace it with a
simple test for IA64_HP_SIM instead.

  [IA64] Improve ia64_leave_syscall() for McKinley-type cores.

  Optimize ia64_leave_syscall() a bit better for McKinley-type cores.
  The patch looks big, but that's mostly due to renaming r16/r17 to r2/r3.
  Good for a 13 cycle improvement.

The problem is that the size of the physical stacked registers was
loaded into the wrong register (r3 instead of r17).  Since r17 by
coincidence always had the value 1, this had the effect of turning
rse_clear_invalid into a no-op.  That poses the risk of leaking kernel
state back to user-land and is hence not acceptable.

The fix below is simple, but unfortunately it costs us about 28 cycles
in syscall overhead. ;-(

Unfortunately, there isn't much we can do about that since those
registers have to be cleared one way or another.

[IA64] Percpu quicklist for combined allocator for pgd/pmd/pte.

This patch introduces using the quicklists for pgd, pmd, and pte levels
by combining the alloc and free functions into a common set of routines.
This greatly simplifies the reading of this header file.

This patch is simple but necessary for large numa configurations.
It simply ensures that only pages from the local node are added to a
cpus quicklist.  This prevents the trapping of pages on a remote nodes
quicklist by starting a process, touching a large number of pages to
fill pmd and pte entries, migrating to another node, and then unmapping
or exiting.  With those conditions, the pages get trapped and if the
machine has more than 100 nodes of the same size, the calculation of
the pgtable high water mark will be larger than any single node so page
table cache flushing will never occur.

I ran lmbench lat_proc fork and lat_proc exec on a zx1 with and without
this patch and did not notice any change.

On an sn2 machine, there was a slight improvement which is possibly
due to pages from other nodes trapped on the test node before starting
the run.  I did not investigate further.

This patch shrinks the quicklist based upon free memory on the node
instead of the high/low water marks.  I have written it to enable
preemption periodically and recalculate the amount to shrink every time
we have freed enough pages that the quicklist size should have grown.
I rescan the nodes zones each pass because other processess may be
draining node memory at the same time as we are adding.

The NAT changes in 2.6.11 changed the position where helpers
are called and perform packet mangling. Before 2.6.11, a NAT
helper was called before the packet was NATed and had its
sequence number adjusted. Since 2.6.11, the helpers get packets
with already adjusted sequence numbers.

This breaks sequence number adjustment, adjust_tcp_sequence()
needs the original sequence number to determine whether
a packet was a retransmission and to store it for further
corrections. It can't be reconstructed without more information
than available, so this patch restores the old order by
calling helpers from a new conntrack hook two priorities
below ip_conntrack_confirm() and adjusting the sequence number

for the bit to re-appear in the cpu_state to get out of the idle loop.
