The system call entry code will clear the high bits of argument
registers before invoking the system call; don't report whatever noise
happens to be in the high bits of the register before that happens.

I suspect this was meant to be added like it was to a whole slew of
other u-boot based boards, but probably just fell through the cracks.

Remove redundant argument check for of_node_get().
It's ok to remove 'node' check because in real life cpm2_pic_init()

- 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
0ffe8000-0ffea000 r--p 00147000 00:01 33082 /lib/libc-2.5.so
0ffea000-0ffed000 rwxp 00149000 00:01 33082 /lib/libc-2.5.so
10000000-10004000 r-xp 00000000 00:01 76 /bin/sleep
10013000-10014000 rwxp 00003000 00:01 76 /bin/sleep
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.

inlined below is the patch that adds physmap driver for of_device.
It's an MTD part of the two-part support for flash/ROM devices based
on Open Firmware descriptions. The arch part (currently only PowerPC
which is no surprise) was introduced to powerpc folks earlier and
recently the older version of the powerpc part has been included into
the powerpc.git tree
(see http://www.kernel.org/git/?p=linux/kernel/git/paulus/powerpc.git;a=commitdiff;h=28f9ec349ae47c91768b7bc5607db4442c818e11).

RedBoot supports storing the FIS directory and the RedBoot
configuration area in the same block of flash memory. This is
not the most common RedBoot configuration, but it is used on
commercially available boards supported by the kernel.
A recent patch to mtd/redboot.c (http://lkml.org/lkml/2006/3/20/410)
which corrected the skipping of deleted table entries has exposed the
latent problem of the kernel redboot parser running off the end of the
FIS directory and interpreting the RedBoot configuration information
as table entries.
This patch terminates the table parsing when the first truly empty
entry is found (table entry deletion only clears the first byte of the
name, so two cleared bytes in a row indicates the end of the table),
thereby supporting the combined redboot FIS directory and RedBoot
configuration information flash layout scenario.

While we're fixing up the newly-added symbol, change the neighbouring ones
too, for consistency and also to reflect the author's interpretation of
the GPL -- which is that _no_ non-GPL modules are permitted. The author
always intended his code to be released under the GPL, and believes that
any new interpretation of 'EXPORT_SYMBOL' as being any different from
'EXPORT_SYMBOL_GPL' is entirely invalid; the GPL requires that _all_
exports have the semantics of the new 'EXPORT_SYMBOL_GPL', which means the
extra four characters are entirely redundant.
But since those four extra characters trigger the check for illegal
modules in a way that just EXPORT_SYMBOL does not, it's useful to change
anyway. This action in no way indicates an admission that there is any
legal distinction between the two states, and in particular does not
indicate that the author believes that non-GPL modules may use symbols
exported with EXPORT_SYMBOL alone.
