The APRP model makes it possible that one or more CPUs run the Linux kernel whereas a dedicated CPU runs special real-time or signal processing program. This patchset adds the following to the current APRP support: 1. Several bug fixes; 2. Running floating point heavy jobs on the RP side; 3. Waking up RP side read by interrupt; 4. CPS multicore APRP support. A mp3 player program was ported to run in the APRP (APSP exactly) model. Considerable performance benefits were observed on the player program. CodeSourcery tools instead of the old SDE tools were used to build the example. Changes: v3 - v2: o Split CMP/MT flavors into different files -cmp/-mt. o Put Malta needed changes into a separate patch. o Code style adjustments in rtlx/vpe files. o Remove kspd.h which might have been left out in Ralf's kspd removal. v2 - v1: o Rebase the patches to the latest kernel, and fix a bunch of warnings and errors reported by the current scripts/checkpatch.pl. o Add MIPS_MALTA dependency to Kconfig since modifications of Malta files are needed. But it should be easy to port changes to other platforms.
