Merge tag 'riscv-for-linus-4.17-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux

Pull RISC-V fixes from Palmer Dabbelt:
 "This contains three small fixes related to the RISC-V port that I'd
  like to target for 4.17-rc3:

   - a Kconfig cleanup to select DMA_DIRECT_OPS instead of redefining it
     in arch/riscv

   - the removal of asm/handle_irq.h, which doesn't exist, from our arch
     header list

   - the addition of "-no-pie" the link rules for our VDSO-related
     files, which fixes the build on systems where PIE is enabled by
     default"
