* MIPS: uasm: Add option to export uasm API.David Daney2010-08-051-1/+1
| | | | | | | | | | | | | | | | A 'select EXPORT_UASM' in Kconfig will cause the uasm to be exported for use in modules. When it is exported, all the uasm data and code cease to be __init and __initdata. Also daddiu_bug cannot be __cpuinitdata if uasm is exported. The cleanest thing is to just make it normal data.

* [MIPS] Add empty argument parenthesis to GCC_IMM_ASMRalf Baechle2008-05-121-1/+1
| | | | | | | | | This is to clarify that GCC_IMM_ASM does not take an argument as the context of the macro's invocation seems to imply. As suggested by Maciej W. Rozycki (macro@linux-mips.org). Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* [MIPS] R4000/R4400 errata workaroundsMaciej W. Rozycki2008-01-291-24/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the gereric part of R4000/R4400 errata workarounds. They include compiler and assembler support as well as some source code modifications to address the problems with some combinations of multiply/divide+shift instructions as well as the daddi and daddiu instructions. Changes included are as follows: 1. New Kconfig options to select workarounds by platforms as necessary. 2. Arch top-level Makefile to pass necessary options to the compiler; also incompatible configurations are detected (-mno-sym32 unsupported as horribly intrusive for little gain). 3. Bug detection updated and shuffled -- the multiply/divide+shift problem is lethal enough that if not worked around it makes the kernel crash in time_init() because of a division by zero; the daddiu erratum might also trigger early potentially, though I have not observed it. On the other hand the daddi detection code requires the exception subsystem to have been initialised (and is there mainly for information). 4. r4k_daddiu_bug() added so that the existence of the erratum can be queried by code at the run time as necessary; useful for generated code like TLB fault and copy/clear page handlers. 5. __udelay() updated as it uses multiplication in inline assembly. Note that -mdaddi requires modified toolchain (which has been maintained by myself and available from my site for ~4years now -- versions covered are GCC 2.95.4 - 4.1.2 and binutils from 2.13 onwards). The -mfix-r4000 and -mfix-r4400 have been standard for a while though. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
