PATCH ppc: Merge a few more include files

Thu Sep 8 06:59:48 EST 2005
Merge a few asm-ppc and asm-ppc64 header files.
Note: the merge of setup.h intentionally does not carry
forward the m68k cruft. That means this patch continues
to break the already broken amiga on the ppc32.

- * upage: 1 page consisting of a user struct that tells gdb
- * what is present in the file. Directly after this is a
- * copy of the task_struct, which is currently not used by gdb,
- * but it may come in handy at some point. All of the registers
- * are stored as part of the upage. The upage should always be
- * only one page long.
- * data: The data segment follows next. We use current->end_text to
- * current->brk to pick up all of the user variables, plus any memory
- * that may have been sbrk'ed. No attempt is made to determine if a
- * page is demand-zero or if a page is totally unused, we just cover
- * the entire range. All of the addresses are rounded in such a way
- * that an integral number of pages is written.
- * stack: We need the stack information in order to get a meaningful
- * backtrace. We need to write the data from usp to
- * current->start_stack, so we round each of these in order to be able
- * to write an integer number of pages.
