This series aims to fix perf for 32-bit systems with a 64-bit time_t
(like RV32).

This series also adds a public futex waitv syscall that userspace
can use to avoid this complexity.

This series hasn't addressed the build failure pointed out in:
https://patchwork.kernel.org/project/linux-riscv/patch/20211209235857.423773-1-alistair.francis@opensource.wdc.com/
as I'm unable to reproduce it and unclear on how it can be fixed.

v6:
 - No change

Alistair Francis (6):
  perf bench futex: Add support for 32-bit systems with 64-bit time_t
  selftests: futex: Call the futex syscall from a function
  uapi: futex: Add a futex syscall
  selftests: futex: Add support for 32-bit systems with 64-bit time_t
  uapi: futex: Add a futex waitv syscall
  selftests: futex: Use futex_waitv helper function
