The "system type" Kconfig options on MIPS are not consistent.  For
some platforms, only the name is listed while other entries are
prepended with "Support for".  Remove this as it doesn't make sense

When debugging a kernel compiled by gcc 4.1 with gdb 6.4, gdb could
not show filename, linenumber, etc.  It seems fixed if I used generic
DWARF_DEBUG macro.  Although gcc 3.x seems work without this change,
it would be better to use the generic macro unless there were
something MIPS specific.

In case of CONFIG_64BIT_PHYS_ADDR, set_pte() and pte_clear() functions
only set _PAGE_GLOBAL bit in the pte_low field of the buddy PTEs,
forgetting to propagate ito to pte_high. Thus, the both pages might not
really be made global for the CPU (since it AND's the G-bit of the
odd / even PTEs together to decide whether they're global or not). Thus,
if only a single page is allocated via vmalloc() or ioremap(), it's not
really global for CPU (and it must be, since this is kernel mapping),
and thus its ASID is compared against the current process' one -- so,
we'll get into trouble sooner or later...  Also, pte_none() will fail
on global pages because _PAGE_GLOBAL bit is set in both pte_low and
pte_high, and pte_val() will return u64 value consisting of those fields
concateneted.

This reverts commit 5491d0f3.

As per Andi:

  "After some discussion with people who have the affected system it
   seems best to revert for 2.6.17.  It broke a common BIOS workaround
   and PCI-X still doesn't work.  Alternative is for people to change
   the BIOS which seems to be better right now."

Actually, we just stumbled on a different bug found in find_e820_area() in
e820.c.  The following code does not handle the edge condition correctly:

   while (bad_addr(&addr, size) && addr+size < ei->addr + ei->size)
       ;
   last = addr + size;
   if ( last > ei->addr + ei->size )
       continue;

The second statement in the while loop needs to be a <= b so that it is the
logical negavite of the if (a > b) outside it. It needs to read:

   while (bad_addr(&addr, size) && addr+size <= ei->addr + ei->size)
       ;

In the case that failed bad_addr was returning an address that is exactly size
bellow the end of the e820 range.

It is possible to boot a Unisys ES7000 with CPUs from multiple cells, and not
also include the memory from those cells.  This can create a scenario where
node 0 has cpus, but no associated memory.  The system will boot fine in a
configuration where node 0 has memory, but nodes 2 and 3 do not.

[AK: I rechecked the code and generic code seems to indeed handle that already.
Dan's original patch had a change for mm/slab.c that seems to be already in now.]

The PM timer code updates vxtime.last_tsc, but this update was done
incorrectly in two ways:
- offset_delay being in microseconds requires multiplying with cpu_mhz
  rather than cpu_khz
- the multiplication of offset_delay and cpu_khz (both being 32-bit
  values) on most current CPUs would overflow (observed value of the
  delay was approximately 4000us, yielding an overflow for frequencies
  starting a little above 1GHz)

ia32_setup_arg_pages would ignore the passed in random stack top
and use its own static value.

Now it uses the 8bit of randomness native i386 would use too.

This indirectly fixes mmap randomization for 32bit processes too,
which depends on the stack randomization.

Should also give slightly better virtual cache colouring and
possibly better performance with HyperThreading.
