Use ELF_BASE_PLATFORM to pass ISA level
Some userland application/program runtime/dynamic loaded need to know about the current ISA level to use the best runtime. While kernel doesn't provides this info. ELF_PLATFORM only provides some info about the CPU, with very few info, for example, the value is "mips" for both 24Kc and P6600. Currently ELF_BASE_PLATFORM is not used by MIPS (only by powerpc). So we cant set its value as: mips2, mips3, mips4, mips5, mips32, mips32r2, mips32r6 mips64, mips64r2, mips64r6 Then in userland, we can get it by: getauxval(AT_BASE_PLATFORM) The only problem is that it seems has different defination than ppc: on ppc, it is the mircoarchitecture while now we use it as ISA level on MIPS.
