Save the Config.OD bit from being clobbered by coherency_setup(). This bit, when set, fixes various errata in the early steppings of Au1x00 SOCs. Unfortunately, the bit was write-only on the most early of them. In addition, also restore the bit after a wakeup from sleep. Signed-off-by:

The modpost uses a whitelist for commonly used suffix on checking the section mismatch. Adding "_ops" suffix to op_modex_xxx get rid of this modpost warning. WARNING: arch/mips/oprofile/oprofile.o - Section mismatch: reference to .init.text: from .data after 'op_model_mipsxx' (at offset 0x528) Signed-off-by:

A proper fix would involve introducing the notion of shared caches but at this stage of 2.6.17 that's going to be too intrusive and not needed for current hardware; aside I think some discussion will be needed. So for now on the affected SMP configurations which happen to suffer from cache aliases we make use of the fact that a single cache will be shared by all processors. This solves the deadlock issue and will improve performance by getting rid of the smp_call_function overhead. Signed-off-by:

The "system type" Kconfig options on MIPS are not consistent. For some platforms, only the name is listed while other entries are prepended with "Support for". Remove this as it doesn't make sense when describing the "system type". Signed-off-by:

When debugging a kernel compiled by gcc 4.1 with gdb 6.4, gdb could not show filename, linenumber, etc. It seems fixed if I used generic DWARF_DEBUG macro. Although gcc 3.x seems work without this change, it would be better to use the generic macro unless there were something MIPS specific. Signed-off-by:

In the branch emulation for floating-point exceptions, __compute_return_epc must determine for bc1f et al which condition code bit to test. This is based on bits <4:2> of the rt field. The switch statement to distinguish bc1f et al needs to use only the two low bits of rt, but the old code tests on the whole rt field. This patch masks off the proper bits. Signed-off-by:

This commit breaks sparse for 64bit kernel. The -m64 option is required. Also, some macro values (such as _MIPS_TUNE, etc.) contain double-quote characters so it would be better quoting arguments by single-quote characters. Signed-off-by:
