MIPS: IP27: Update/restructure CPU overrides
Inspired by Maciej's recent patch to update DEC cpu-feature-overrides.h, I updated IP27's as well to disable features known to not apply to the IP27 platform or the R10K-series of CPUs. Before: text data bss dec hex filename 8616648 463200 472240 9552088 91c0d8 vmlinux After: text data bss dec hex filename 8592256 471392 472240 9535888 918190 vmlinux I believe the increase in the size of the data section is for the same reasons as in the DEC patch.
