RISC-V Updates for 4.21-rc2 v2

This tag contains a handful of updates that slipped through the cracks
during the merge window due to the holidays.  The fixes are mostly
independent, with the exception of one larger audit-related branch.
There's more information about the audit branch in that merge, the rest
are:

* The BSS has been moved, which shrinks flat images.
* A fix to test-bpf so it compiles on RV64I-based systems.
* A fix to respect the kernel commandline when there is no device tree.
* A fix to prevent CPUs from trying to put themselves to sleep when
  bringing down the system.
* Support for MODULE_SECTIONS on RV32I-based systems.
* [new in v2] The addition of an SBI earlycon driver.  This is
  definately a new feature, but I'd like to include it now because I
  dropped this patch when submitting the merge window PR that removed our
  EARLY_PRINTK support.

As usual, I've tested this by booting a Fedora-based image on a recent
QEMU (this time just whatever I had lying around).

---

Just a note: I did find when testing that the generic PCI controller hangs
boots on QEMU.  Everything is unstable (rc1 kernel, QEMU in merge window, and
I've never tried this specific PCI controller before) so it's probably not a
regression, but it's definately a bug.
