RISC-V Patches for 5.1-rc4

I dropped the ball a bit here: these patches should all probably have
been part of rc2, but I wanted to get around to properly testing them in
the various configurations (qemu32, qeum64, unleashed) first.
Unfortunately I've been traveling and didn't have time to actually do
that, but since these fix concrete bugs and pass my old set of tests I
don't want to delay the fixes any longer.

There are four independent fixes here:

* A fix for the rv32 port that corrects the 64-bit user accesor's fixup
  label address.
* A fix for a regression introduced during the merge window that broke
  medlow configurations at run time.  This patch also includes a fix
  that disables ftrace for the same set of functions, which was found by
  inspection at the same time.
* A modification of the memory map to avoid overlapping the FIXMAP and
  VMALLOC regions on systems with small memory maps.
* A fix to the module handling code to use the correct syntax for
  probing Kconfig entries.

These have passed my standard test flow, but I didn't have time to
expand that like I said I would.
