- Drivers will not rely on the PCI config space value, as they've
  already been conditioned to rely on the irq field in "struct pci_dev".

- The virq value may not be < 256 as it has been remapped.

- The PCI config space should reflect the hardware configuration, which
  is not being changed.  We are only creating a virtual irq mapping that
  exists in the kernel only. One would never expect the PCI hardware to
  generate the "virq" interrupt.

I often test new versions of glibc by doing:

LD_LIBRARY_PATH=/XXX/lib /XXX/lib/ld.so.1 <binary>

One test case ended up SEGV'ing. Upon closer inspection ld.so was loaded
at 0x8000000 (128MB) with the heap right after it. Since we normally
link binaries at 0x10000000 (256MB) we only had about 128MB of space for
the heap:

00100000-00103000 r-xp 00100000 00:00 0           [vdso]
08000000-0801e000 r-xp 00000000 00:01 33079       /lib/ld-2.5.so
0802d000-0802f000 rwxp 0001d000 00:01 33079       /lib/ld-2.5.so
0802f000-08050000 rwxp 0802f000 00:00 0           [heap]
0fe91000-0ffd9000 r-xp 00000000 00:01 33082       /lib/libc-2.5.so
0ffd9000-0ffe8000 ---p 00148000 00:01 33082       /lib/libc-2.5.so

ffb41000-ffb56000 rw-p ffb41000 00:00 0           [stack]

One way to fix this is move ELF_ET_DYN_BASE from 0x08000000 to 0x20000000.
This allows 128MB for the binary (hopefully enough for even the most
crazy c++ apps), and with our current layout we will grow the heap up
and the stack down, allowing potentially gigabytes of heap:

00100000-00103000 r-xp 00100000 00:00 0           [vdso]

The current PDA code, which went in in post 2.6.19 has a flaw in that it
doesn't correctly cycle the GDT and %GS segment through the boot PDA,
the CPU PDA and finally the per-cpu PDA.

The bug generally doesn't show up if the boot CPU id is zero, but
everything falls apart for a non zero boot CPU id.  The basically kills
voyager which is perfectly capable of doing non zero CPU id boots, so
voyager currently won't boot without this.

The fix is to be careful and actually do the GDT setups correctly.

Different AX88772 dongles use different PHYs; the chip is capable of using
both a primary and secondary PHY, and supports an internal and external PHY.

It appears that some DUB-E100 devices use the internal PHY, so trying to use
an external one will not work (note that this is different across revisions,
as well; the "A" and "B" revs of the DUB-E100 use different PHYs!).  The data
sheet for the AX88772 chip specifies that the internal PHY id will be 0x10,
so if that's read from the EEPROM, we should use that rather than attempting
to use an external PHY.

  "Nadia Derbey has reported that mmap of /dev/kmem no longer works with
   the kernel virtual address as offset, and Franck has confirmed that
   his patch came from a misunderstanding of what an offset means to
   /dev/kmem - whereas his patch description seems to say that he was
   correcting the offset on a few plaforms, there was no such problem to
   correct, and his patch was in fact changing its API on all platforms."

On 64-bit machines, if an atomic counter is explicitly set to a
negative value, the atomic_dec_if_positive function will decrement and
store the next smallest value in the atomic counter, contrary to its
intended operation.

The comparison to determine if the decrement will make the result
negative was done by the "addic." instruction, which operates on a
64-bit value, namely the zero-extended word loaded from the atomic
variable.  This patch uses an explicit word compare (cmpwi) and
changes the addic. to an addi (also changing "=&r" to "=&b" so that r0
isn't used, and addi doesn't become li).

This also fixes a bug for both 32-bit and 64-bit in that previously
0x80000000 was considered positive, since the result after
decrementing is positive.  Now it is considered negative.

Also, I clarify the return value in the comments just to make it clear
that the value returned is always the decremented value, even if that
value is not stored back to the atomic counter.
