Pull RISC-V updates from Palmer Dabbelt:
 "This contains some small RISC-V updates I'd like to target for 4.18.

  They are all fairly small this time. Here's a short summary, there's
  more info in the commits/merges:

   - a fix to __clear_user to respect the passed arguments.

   - enough support for the perf subsystem to work with RISC-V's ISA
     defined performance counters.

   - support for sparse and cleanups suggested by it.

   - support for R_RISCV_32 (a relocation, not the 32-bit ISA).

   - some MAINTAINERS cleanups.

   - the addition of CONFIG_HVC_RISCV_SBI to our defconfig, as it's
     always present.

  I've given these a simple build+boot test"
