powerpc/ppc32: static ftrace fixes for PPC32

2008-11-28T13:08:07Z

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. Signed-off-by: Steven Rostedt Signed-off-by: Ingo Molnar

powerpc: Remove use of CONFIG_PPC_MERGE

2008-08-04T03:18:17Z

Now that arch/ppc is gone and CONFIG_PPC_MERGE is always set, remove the dead code associated with !CONFIG_PPC_MERGE from arch/powerpc and include/asm-powerpc. Signed-off-by: Kumar Gala Signed-off-by: Paul Mackerras

powerpc: Add self-tests of the feature fixup code

2008-07-01T01:28:30Z

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. Signed-off-by: Michael Ellerman Signed-off-by: Paul Mackerras

powerpc: Split out do_feature_fixups() from cputable.c

2008-07-01T01:28:24Z

The logic to patch CPU feature sections lives in cputable.c, but these days it's used for CPU features as well as firmware features. Move it into it's own file for neatness and as preparation for some additions. While we're moving the code, we pull the loop body logic into a separate routine, and remove a comment which doesn't apply anymore.

powerpc: Move code patching code into arch/powerpc/lib/code-patching.c

2008-07-01T01:28:18Z

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] Fix -Os kernel builds with newer gcc versions

2008-06-16T05:00:54Z

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. Signed-off-by: Kumar Gala Signed-off-by: Paul Mackerras

[POWERPC] ppc: More compile fixes

2008-05-12T12:57:51Z

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. Signed-off-by: Paul Mackerras

[POWERPC] devres: Add devm_ioremap_prot()

2008-05-05T06:47:14Z

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

2007-10-16T23:09:21Z

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. Signed-off-by: Sylvain Munaut Signed-off-by: Grant Likely
