This creates the directory structure under arch/powerpc and a bunch of Kconfig files. It does a first-cut merge of arch/powerpc/mm, arch/powerpc/lib and arch/powerpc/platforms/powermac. This is enough to build a 32-bit powermac kernel with ARCH=powerpc. For now we are getting some unmerged files from arch/ppc/kernel and arch/ppc/syslib, or arch/ppc64/kernel. This makes some minor changes to files in those directories and files outside arch/powerpc. The boot directory is still not merged. That's going to be interesting.

|
Some PReP systems have residual data passed to the kernel by the
|
|
firmware. This allows detection of memory size, devices present and
|
|
other useful pieces of information. Sometimes this information is
|
|
not present or incorrect, in which case it could lead to the machine
|
|
behaving incorrectly. If this happens, either disable PREP_RESIDUAL
|
|
or pass the 'noresidual' option to the kernel.
|
|
|
|
If you are running a PReP system, say Y here, otherwise say N.

help
|
|
Enabling this option will create a /proc/residual file which allows
|
|
you to get at the residual data on PReP systems. You will need a tool
|
|
(lsresidual) to parse it. If you aren't on a PReP system, you don't
|
|
want this.
