Restructure of arch/ppc/kernel and include/asm-ppc

[Douglas Godfrey]

Power MachTen implements a Unix Filesystem on top of the Mac HFS filesystem.
There are restrictions on path length, file/filder names and non alphanumeric
characters allowed in Unix files to allow mapping unix files to Mac OS files.
The main restrictions are 32byte name length limit and the mapping of the
":" <--> "/" and problems with files that start with "." (Norton Utilities
will remove the "." thereby breaking the Unix file system).

Linux could then co-exist with the Mac OS with the Linux Scheduler and Memory
Management system taking over forom the Mac OS (each Mac OS task becomes a
Linux task with protected memmory). This is how MachTen for the 68k worked.
