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" * tag 'riscv-for-linus-4.17-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux: RISC-V: build vdso-dummy.o with -no-pie riscv: there is no <asm/handle_irq.h> riscv: select DMA_DIRECT_OPS instead of redefining it
