MIPS: Separate two consecutive loads in memset.S

2010-12-16T18:10:57+00:00

partial_fixup is used in noreorder block.

Separating two consecutive loads can save one cycle on processors with
GPR intrelock and can fix load-use on processors that need a load delay slot.

Also do so for fwd_fixup.

[Ralf: Only R2000/R3000 class processors are lacking the the load-user
interlock and even some of those got it retrofitted.  With R2000/R3000
being fairly uncommon these days the impact of this bug should be minor.]

MIPS: Outline udelay and fix a few issues.

2009-06-08T15:57:51+00:00

Outlining fixes the issue were on certain CPUs such as the R10000 family
the delay loop would need an extra cycle if it overlaps a cacheline
boundary.

The rewrite also fixes build errors with GCC 4.4 which was changed in
way incompatible with the kernel's inline assembly.

Relying on pure C for computation of the delay value removes the need for
explicit.  The price we pay is a slight slowdown of the computation - to
be fixed on another day.

MIPS: IP27: Switch from DMA_IP27 to DMA_COHERENT

2009-01-30T21:32:58+00:00

The special IP27 DMA code selected by DMA_IP27 has been removed a while
ago turning DMA_IP27 into almost a nop.  Also fixup the broken logic of
its last users memcpy.S and memcpy-inatomic.s.

MIPS: Hook up Cavium OCTEON in arch/mips.

2009-01-11T09:57:22+00:00

Take all the OCTEON specific files that were added, and hook them into
the build system for the arch/mips.  For versions of GCC that lack
OCTEON support, override gas target architecture.
