  riscv: Fixup bootup failure with HARDENED_USERCOPY (2020-10-06 18:34:00 -0700)

RISC-V Fixes for 5.9

I have two fixes this week:

* A fix to actually reserve the device tree's memory.  Without this the device
  tree can be overwritten on systems that don't otherwise reserve it.  This
  issue should only manifest on !MMU systems.
* A workaround for a BUG() that triggers when the memory that originally
  contained initdata is freed and later repurposed.  This triggers a BUG() on
  builds that with HARDENED_USERCOPY enabled.

Sorry, I hadn't seen that when I'd posted the PR.  It looks like there's a
jitterentropy fix in the works, I'll drop the export when that lands.  Probably
best to talk on that thread, though, as there's more context over there.

Err, haven't we just agreed on that this is a bad idea and jitterentropy
should not call get_cycles()?

  RISC-V: Check clint_time_val before use (2020-09-30 11:05:14 -0700)

----------------------------------------------------------------
RISC-V Fixes for 5.9

I have two fixes for this week:

* The addition of a symbol export for clint_time_val, which has been inlined
  into some timex functions and can be used by drivers.
* A fix to avoid calling get_cycles() before the timers have been probed.

These both only effect !MMU systems.
