  riscv: enable THP_SWAP for RV64 (2022-10-06 20:03:48 -0700)

----------------------------------------------------------------
RISC-V Patches for the 6.1 Merge Window, Part 1

* Improvements to the CPU topology subsystem, which fix some issues
  where RISC-V would report bad topology information.
* The default NR_CPUS has increased to XLEN, and the maximum
  configurable value is 512.
* The CD-ROM filesystems have been enabled in the defconfig.
* Support for THP_SWAP has been added for rv64 systems.

There are also a handful of cleanups and fixes throughout the tree.

----------------------------------------------------------------
I will almost certainly have a part 2 for next week, but I'm not sure how big
it will be: between the conferences and COVID things have been a mess on my
end, that's clearly made this first week pretty small but it's also meant a lot
of stuff on the lists still needs work.  There's also some stuff that's pending
on conflicts, though, so I figured it'd be best to just send this today to make
handling those easier.

I'm still seeing some of these KASAN/pcpu_alloc related panics, but it doesn't
seem like they're more common with these than they are on 6.0 so I think it's
OK to just call these safe.  Aside from that things seem fine with this merged
into master from this morning.
