powerpc: Merge enough to start building in arch/powerpc. This creates the directory structure under arch/powerpc and a bunch of Kconfig files. It does a first-cut merge of arch/powerpc/mm, arch/powerpc/lib and arch/powerpc/platforms/powermac. This is enough to build a 32-bit powermac kernel with ARCH=powerpc. For now we are getting some unmerged files from arch/ppc/kernel and arch/ppc/syslib, or arch/ppc64/kernel. This makes some minor changes to files in those directories and files outside arch/powerpc. The boot directory is still not merged. That's going to be interesting. Signed-off-by: Paul Mackerras <paulus@samba.org>

powerpc: Add configurable -Werror for arch/powerpc Add the option to build the code under arch/powerpc with -Werror. The intention is to make it harder for people to inadvertantly introduce warnings in the arch/powerpc code. It needs to be configurable so that if a warning is introduced, people can easily work around it while it's being fixed. The option is a negative, ie. don't enable -Werror, so that it will be turned on for allyes and allmodconfig builds. The default is n, in the hope that developers will build with -Werror, that will probably lead to some build breaks, I am prepared to be flamed. It's not enabled for math-emu, which is a steaming pile of warnings. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

powerpc/ppc32: static ftrace fixes for PPC32 Impact: fix for PowerPC 32 code There were some early init code that was not safe for static ftrace to boot on my PowerBook. This code must only use relative addressing, and static mcount performs a compare of the ftrace_trace_function pointer, and gets that with an absolute address. In the early init boot up code, this will cause a fault. This patch removes tracing from the files containing the offending functions.

[POWERPC] Fix -Os kernel builds with newer gcc versions 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 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 <asm/irq.h> in setup.c for the __DO_IRQ_CANON definition. 3. Include <linux/proc_fs.h> 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. Signed-off-by: Paul Mackerras <paulus@samba.org>

powerpc: Merge xmon The merged version follows the ppc64 version pretty closely mostly, and in fact ARCH=ppc64 now uses the arch/powerpc/xmon version. The main difference for ppc64 is that the 'p' command to call show_state (which was always pretty dodgy) has been replaced by the ppc32 'p' command, which calls a given procedure (so in fact the old 'p' command behaviour can be achieved with 'p $show_state').

powerpc: Move code patching code into arch/powerpc/lib/code-patching.c We currently have a few routines for patching code in asm/system.h, because they didn't fit anywhere else. I'd like to clean them up a little and add some more, so first move them into a dedicated C file - they don't need to be inlined. While we're moving the code, drop create_function_call(), it's intended caller never got merged and will be replaced in future with something different.

powerpc: Add self-tests of the feature fixup code This commit adds tests of the feature fixup code, they are run during boot if CONFIG_FTR_FIXUP_SELFTEST=y. Some of the tests manually invoke the patching routines to check their behaviour, and others use the macros and so are patched during the normal patching done during boot. Because we have two sets of macros with different names, we use a macro to generate the test of the macros, very niiiice.
