Kuribayashi-san,

I will certainly remove CONFIG_CPU_HAS_LLSC, thank you. I attempted to enable 'cpu_has_clo_clz' for SEAD-3, but it breaks my microMIPS-only kernel builds. Specifically, since microMIPS LL/SC instructions do not have 16-bit address offsets, in the '__cmpxchg_asm' macro function I get constraint errors because then the assembler has to use the %LO register in order to calculate the offset address. I am going to hold off on enabling the option until after the 3.5 release and then revisit for a solution. Thank you.

-Steve
