[PATCH for-4.20 0/3] RISCV: Bugfixes and UBSAN

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

One bugfix, and two minor patches to get UBSAN working with RISCV.  They
should be considered for 4.20 at this juncture.

I tried to get this working everywhere, but:

1) ARM32 has some problem with dump_execution_state() and dies with an
   undefined instruction error.

2) PPC doesn't get any console output, and also appears to have no exception
   handling either.  Also, when it doesn't succeed, it takes ages to fail.

Andrew Cooper (3):
  RISCV/boot: Run constructors during setup
  RISCV/asm: Use CALL rather than JAL
  RISCV: Activate UBSAN in testing
