Evan Green d3d2cf1aca RISC-V: Show accurate per-hart isa in /proc/cpuinfo ... In /proc/cpuinfo, most of the information we show for each processor is specific to that hart: marchid, mvendorid, mimpid, processor, hart, compatible, and the mmu size. But the ISA string gets filtered through a lowest common denominator mask, so that if one CPU is missing an ISA extension, no CPUs will show it. Now that we track the ISA extensions for each hart, let's report ISA extension info accurately per-hart in /proc/cpuinfo. We cannot change the "isa:" line, as usermode may be relying on that line to show only the common set of extensions supported across all harts. Add a new "hart isa" line instead, which reports the true set of extensions for that hart.
