c49888203d powerpc: Fixes to get the Longtrail CHRP a bit further
Talk about buggy firmware...  the OF on the Longtrail returns 0
from the claim client service rather than -1 when the claim fails.
It also has no device_type on the /memory node and blows up if
the output buffer for package-to-path is too big.

This also fixes a bug with calling alloc_up with align == 0, where
we did _ALIGN_UP(alloc_bottom, 0) which will end up as 0.

Lastly, we now check the return value (in r3) from calling the
prom, and return -1 from call_prom if we get a negative value back.
That is supposed to indicate that the requested client service
doesn't exist.

85e568ea58 powerpc: Make coff boot wrapper load the kernel at 8M
Previously it claimed 7MB starting at the 9M point and loaded the
kernel there.  That meant that prom_init put the flattened device
tree above 16M.  On the 601 that caused the early device tree scan
to fail, since only 16MB are mapped with BATs on the 601.  Moving
this down to 8MB allows prom_init to put the flattened device tree
between 15M and 16M, so it works on the 601.

9fcdfcd905 [PATCH] ppc32 ld.script fix for building on ppc64
In arch/ppc/boot/ld.script we need OUTPUT_ARCH(powerpc:common) for the
same reasons why we need it in vmlinux.lds.S; when we build on ppc64
box, we need to be explicit about the target.

See http://linus.bkbits.net:8080/linux-2.5/cset@1.1784.8.10 for the
corresponding fix in vmlinux.lds.S.

66b375bf7d [PATCH] ppc32: In the boot code, don't rely on BASE_BAUD directly
Modifies serial_init to get base baud rate from the rs_table entry instead
of BAUD_BASE.  This patch eliminates duplication between the
SERIAL_PORT_DFNS macro and BAUD_BASE.  Without the patch, if a port set the
baud rate in SERIAL_PORT_DFNS, but did not update BASE_BAUD, the BASE_BAUD
value would still be used.

2e2446ea07 [PATCH] Remove NACA fixed address constraint
Comments in head.S suggest that the iSeries naca has a fixed address,
because tools expect to find it there.  The only tool which appears to
access the naca is addRamDisk, but both the in-kernel version and the
version used in RHEL and SuSE in fact locate the NACA the same way as
the hypervisor does, by following the pointer in the hvReleaseData
structure.

Since the requirement for a fixed address seems to be obsolete, this
patch removes the naca from head.S and replaces it with a normal C
initializer.

For good measure, it removes an old version of addRamDisk.c which was
sitting, unused, in the ppc32 tree.

This patch kills the whole embedded System.map mecanism and the
bootloader-passed System.map that was used to provide symbol resolution in

No hurry getting that in Linus tree, let it be tested in -mm for a while
first and make sure it doesn't break various embedded configs.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
