  RISC-V: recognize S/U mode bits in print_isa (2018-11-20 05:19:28 -0800)

RISC-V Patches for 4.20-rc4

This week is a bit bigger than I expected.  That's my fault, as I missed
a few patches while I was at Plumbers last week.  We have:

* A fix to a quite embarassing issue where raw_copy_to_user() was
  implemented with asm_copy_from_user() (and vice versa).
* Improvements to our makefile to allow flat binaries to be generated.
* A build fix that predeclares "struct module" at the top of
  <asm/module.h>, which triggers warnings later in that header.
* The addition of our own <uapi/asm/unistd> header, which is necessary
  to align our stat ABI on 32-bit systems.
* A fix to avoid printing a warning when the S or U bits are set in
  print_isa().

I already have one patch in the queue for next week.
