2014-03-31MIPS: Fix gigaton of warning building with microMIPS.Ralf Baechle
With binutils 2.24 the attempt to switch with microMIPS mode to MIPS III mode through .set mips3 results in *lots* of warnings like {standard input}: Assembler messages: {standard input}:397: Warning: the 64-bit MIPS architecture does not support the `smartmips' extension during a kernel build. Fixed by using .set arch=r4000 instead. This breaks support for building the kernel with binutils 2.13 which was supported for 32 bit kernels only anyway and 2.14 which was a bad vintage for MIPS anyway.

2014-03-26MIPS: asm: Add wrappers for EVA/non-EVA instructionsMarkos Chandras
EVA uses specific instructions for accessing user memory. Instead of polluting the kernel with numerous #ifdef CONFIG_EVA we add wrappers for all the instructions that need special handling when EVA is enabled. Signed-off-by: Markos Chandras <markos.chandras@imgtec.com>
2014-03-26MIPS: asm: Add prefetch instruction for EVALeonid Yegoshin
EVA can use the PREFE instruction to perform the virtual address translation using the user mapping of the address rather than the kernel mapping. Signed-off-by: Leonid Yegoshin <Leonid.Yegoshin@imgtec.com> Signed-off-by: Markos Chandras <markos.chandras@imgtec.com>
2013-05-09MIPS: microMIPS: Optimise 'memset' core library function.Steven J. Hill
Optimise 'memset' to use microMIPS instructions and/or optimisations for binary size reduction. When the microMIPS ISA is not being used, the library function compiles to the original binary code. Signed-off-by: Steven J. Hill <Steven.Hill@imgtec.com>
2013-02-01MIPS: Whitespace cleanup.Ralf Baechle
Having received another series of whitespace patches I decided to do this once and for all rather than dealing with this kind of patches trickling in forever. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
