Becky Bruce 1ac9f1f71d [POWERPC] Update lmb.h include protection to ASM_POWERPC
This file was protected by _PPC64_LMB_H, which is confusing, as the
32-bit code also uses the lmb these days.  Changed to
_ASM_POWERPC_LMB_H.

Michael Ellerman f8642ebee8 [PATCH] powerpc: Remove calculation of io hole
In mm_init_ppc64() we calculate the location of the "IO hole", but then
no one ever looks at the value. So don't bother.

That's actually all mm_init_ppc64() does, so get rid of it too.

Michael Ellerman 56b5c9737c [PATCH] powerpc: Put parameter names in lmb.h prototypes
Prototypes aren't so useful without parameter names, add them to lmb.h based
on the names in lmb.c

Michael Ellerman 3b9331dac1 [PATCH] powerpc: Move LMB_ALLOC_ANYWHERE out of lmb.h
LMB_ALLOC_ANYWHERE doesn't need to be part of the API, it's only used in
lmb.c - so move it out of the header file.

Michael Ellerman d7a5b2ffa1 [PATCH] powerpc: Always panic if lmb_alloc() fails
Currently most callers of lmb_alloc() don't check if it worked or not, if it
ever does weird bad things will probably happen. The few callers who do check
just panic or BUG_ON.

So make lmb_alloc() panic internally, to catch bugs at the source. The few
callers who did check the result no longer need to.

The only caller that did anything interesting with the return result was
careful_allocation(). For it we create __lmb_alloc_base() which _doesn't_ panic
automatically, a little messy, but passable.

Arnd Bergmann 88ced03149 [PATCH] powerpc: sanitize header files for user space includes
include/asm-ppc/ had #ifdef __KERNEL__ in all header files that
are not meant for use by user space, include/asm-powerpc does
not have this yet.

This patch gets us a lot closer there. There are a few cases
where I was not sure, so I left them out. I have verified
that no CONFIG_* symbols are used outside of __KERNEL__
any more and that there are no obvious compile errors when
including any of the headers in user space libraries.

Paul Mackerras 9b6b563c0d powerpc: Merge in the ppc64 version of the prom code.
This brings in the ppc64 version of prom_init.c, prom.c and btext.c
and makes them work for ppc32.  This also brings in the new calling
convention, where the first entry to the kernel (with r5 != 0) goes
to the prom_init code, which then restarts from the beginning (with
r5 == 0) after it has done its stuff.

For now this also brings in the ppc32 version of setup.c.  It also
merges lmb.h.
