The SGI Altix PROM supports a SAL call for performance monitoring and for
exporting NUMA topology. We need this in community kernels for diagnostic
and performance tools to use, especially on very large machines.

This patch registers a dynamic misc device "sn_hwperf" that supports an
ioctl interface for reading/writing memory mapped registers on Altix
nodes and routers via the new SAL call. It also creates a read-only
procfs file "/proc/sgi_sn/sn_topology" to export NUMA topology and Altix
hardware inventory.

> What tools are using this?
 
Performance Co-Pilot http://oss.sgi.com/projects/pcp  in particular,
pmshub, shubstats and linkstat. Numerous other users include anything
that needs knowledge of numa topology/interconnect in order to perform
well, e.g. mpt. BTW I have not exported any API functions .. at this
point I don't think we need any modules to call the API.

r.k[56] used to contain physical addresses but now contain virtual
addresses.  There are code remnants which still believe that they are
physical and "convert" ar.k[56] to virtual.  This breaks when current
is not in region 7 (e.g. the idle task on cpu 0).

The compiler has no way of knowing whether nentries will be greater than 0, so
it was generating a warning that qw might be used uninitialized.  Fix it by
explicitly setting it to 0.  Cc'ing Brian in case he has an internal version
he'd like to keep in sync.

Thanks to David for his help in tracking it down.

  compile the kernel with sibling call optimization
  turned off. There is a problem with all functions
  using the optimization and the asmlinkage attribute.
  The compiler should not perform the optimization on
  these functions because it cannot preserve the syscall
  parameters in the callee. This caused SIGSEGV on programs
  traced with PTRACE_SYSCALL, for instance.

This patch kills the bogus radeonfb_read/write routines. In order to do so,
it adds a new member to fb_info, along with screen_base, which is screen_size,
indicating the mapped area. The default fb_read/write will now use that instead
of fix->smem_len if it is non-0, and radeonfb now sets it to the mapped size
of the framebuffer.

Am travelling, but this passed simple tests here.  If this isn't going
in, the current seqfile stuff should be ripped out; it's a mess.

/proc/net/ip_conntrack was changed over to seq_file.  However,
seq_file isn't a great fit (a linked list which is changing is not a
good candidate for seq file), and the conversion was done badly.

1) Don't do allocation: simply hand the pointer head of the correct chain.
2) Actually output the original tuple.
3) Lock only when actually traversing hash chain.

	Appended is a 2nd version that uses nf_reset_debug.

- do not use skb_checksum_help in input path as ipvs can handle
incoming CHECKSUM_HW packets

- do not use skb_checksum_help in forwarding path

- claim that checksum is valid (CHECKSUM_NONE) when entering output
path for out->in packets

- do not reset/destroy the nfct in IP_VS_XMIT, the intention is to
reset the debugging field just to avoid log floods from nf_debug_ip_*
functions, it is known that the ipvs packets traverse other
hooks, eg. LOCAL_IN->LOCAL_OUT. Use nf_reset_debug instead of nf_reset.

This fixes panic in rt6_device_match().

Well, rt->rt6i_idev is always set if it is dynamically allocated.
However, when we hit ip6_null_entry here, its rt6i_idev is NULL.

1. If the fake 5513 id bit is not set by the BIOS we must have the 5518
id in the device table.

2. If the register remapping is not set by the BIOS then the enable bit
check in ide_pci_setup_ports will fail. It's safe to switch to the
remapping mode here. Keeping the not remapped mode would need quite big
changes AFAICS.

Forward ported to 2.6 by me.

This driver caused a _lot_ of warnings due to tons
of explicit casts to "uclong". Making all the types
sane not only removed the warnings, but got rid of
a lot of silly casting, since the types are now much
more natural to what the driver wanted to do in the
first place.

Forgot to add in the mmio base..

It disappeared somewhere in Al's cleanup patch..
