[POWERPC] Fix -Os kernel builds with newer gcc versions

2008-06-16T05:00:54+00:00

GCC 4.4.x looks to be adding support for generating out-of-line register
saves/restores based on:

http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html

This breaks the kernel if we enable CONFIG_CC_OPTIMIZE_FOR_SIZE.  To fix
this we add the use the save/restore code from gcc and simplified it down
for our needs (integer only).

Additionally, we have to link this code into each module.  The other
solution was to add EXPORT_SYMBOL() which meant going through the
trampoline which seemed nonsensical for these out-of-line routines.

Finally, we add some checks to prom_init_check.sh to ignore the
out-of-line save/restore functions.

[POWERPC] ppc: More compile fixes

2008-05-12T12:57:51+00:00

This fixes a few more miscellaneous compile problems with ARCH=ppc.

1. Don't compile devres.c on ARCH=ppc, it doesn't have ioremap_flags.
2. Include  in setup.c for the __DO_IRQ_CANON definition.
3. Include  in residual.c for the
   definition of create_proc_read_entry.
4. Fix xchg_ptr to be a static inline to eliminate a compiler warning.

[POWERPC] devres: Add devm_ioremap_prot()

2008-05-05T06:47:14+00:00

We provide an ioremap_flags, so this provides a corresponding
devm_ioremap_prot.  The slight name difference is at Ben
Herrenschmidt's request as he plans on changing ioremap_flags to
ioremap_prot in the future.

[POWERPC] rheap: Changes config mechanism

2007-10-16T23:09:21+00:00

Instead of having in the makefile all the option that
requires rheap, we define a configuration symbol
and when needed we make sure it's selected.

[POWERPC] Create and use CONFIG_WORD_SIZE

2007-10-02T23:12:02+00:00

Linus made this suggestion for the x86 merge and this starts the process
for powerpc.  We assume that CONFIG_PPC64 implies CONFIG_PPC_MERGE and
CONFIG_PPC_STD_MMU_32 implies CONFIG_PPC_STD_MMU.

[POWERPC] Fix section mismatch in PCI code

2007-09-19T05:25:34+00:00

Create a helper function (alloc_maybe_bootmem) that is marked __init_refok
to limit the chances of mistakenly referring to other __init routines.

[POWERPC] Added kprobes support to ppc32

[POWERPC] 8xx: generic 8xx code arch/powerpc port

2007-02-07T03:01:02+00:00

Including support for non-coherent cache, some mm-related things +
relevant field in Kconfig and Makefiles. Also included rheap.o compilation
if 8xx is defined.

Non-coherent mapping were refined and renamed according to Cristoph
Hellwig. Orphaned functions were cleaned up.

[Also removed arch/ppc/kernel/dma-mapping.c, because otherwise
compiling with ARCH=ppc for a non DMA-cache-coherent platform ends up
with two copies of __dma_alloc_coherent etc.
