powerpc: Move include files to arch/powerpc/include/asm

2008-08-04T02:02:00+00:00

from include/asm-powerpc.  This is the result of a

mkdir arch/powerpc/include/asm
git mv include/asm-powerpc/* arch/powerpc/include/asm

Followed by a few documentation/comment fixups and a couple of places
where  was being used explicitly.  Of the latter only
one was outside the arch code and it is a driver only built for powerpc.

[POWERPC] Use lowmem_end_addr to limit lmb allocations on ppc32

2008-04-16T21:46:13+00:00

Now that we have a proper variable that is the address of the top
of low memory we can use it to limit the lmb allocations.

[LIB]: Make PowerPC LMB code generic so sparc64 can use it too.

[POWERPC] Fix handling of memreserve if the range lands in highmem

2008-01-24T01:29:08+00:00

There were several issues if a memreserve range existed and happened
to be in highmem:

* The bootmem allocator is only aware of lowmem so calling
  reserve_bootmem with a highmem address would cause a BUG_ON
* All highmem pages were provided to the buddy allocator

Added a lmb_is_reserved() api that we now use to determine if a highem
page should continue to be PageReserved or provided to the buddy
allocator.

Also, we incorrectly reported the amount of pages reserved since all
highmem pages are initally marked reserved and we clear the
PageReserved flag as we "free" up the highmem pages.

[POWERPC] Update lmb.h include protection to ASM_POWERPC

2007-08-17T01:01:58+00:00

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.

[PATCH] powerpc: Remove calculation of io hole

2006-03-22T04:04:30+00:00

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.

[PATCH] powerpc: Put parameter names in lmb.h prototypes

2006-02-07T11:38:37+00:00

Prototypes aren't so useful without parameter names, add them to lmb.h based
on the names in lmb.c

[PATCH] powerpc: Move LMB_ALLOC_ANYWHERE out of lmb.h

2006-02-07T11:38:36+00:00

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.

[PATCH] powerpc: Always panic if lmb_alloc() fails

2006-02-07T11:38:34+00:00

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.

[PATCH] powerpc: sanitize header files for user space includes

2006-01-09T04:13:08+00:00

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.
