  riscv: fix build break after macro-to-function conversion in generic cacheflush.h (2019-07-18 08:16:56 -0700)

----------------------------------------------------------------
RISC-V updates for v5.3

- Hugepage support

- "Image" header support for RISC-V kernel binaries, compatible with
  the current ARM64 "Image" header

- Initial page table setup now split into two stages

- CONFIG_SOC support (starting with SiFive SoCs)

- Avoid reserving memory between RAM start and the kernel in setup_bootmem()

- Enable high-res timers and dynamic tick in the RV64 defconfig

- Remove long-deprecated gate area stubs

- MAINTAINERS updates to switch to the newly-created shared RISC-V git
  tree, and to fix a get_maintainers.pl issue for patches involving
  SiFive E-mail addresses

Also, one integration fix to resolve a build problem introduced during
in the v5.3-rc1 merge window:

- Fix build break after macro-to-function conversion in
  asm-generic/cacheflush.h
