[GIT PULL] RISC-V updates for v5.3

[GIT PULL] RISC-V updates for v5.3

[Paul Walmsley]

Linus,

I inadvertently based these changes on the commit immediately 
preceding the v5.3-rc1 tag, rather than the v5.3-rc1 tag itself.  Let me 
know if you'd like us to rebase them.

  riscv: dts: Add DT node for SiFive FU540 Ethernet controller driver (2019-07-22 14:49:31 -0700)

----------------------------------------------------------------
RISC-V updates for v5.3-rc2

Four minor RISC-V-related changes for v5.3-rc2:

- Add support for the new clone3 syscall for RV64, relying on the
  generic support

- Add DT data for the gigabit Ethernet controller on the SiFive FU540
  and the HiFive Unleashed board

- Update MAINTAINERS to add me to the arch/riscv maintainers' list

- Add support for PCIe message-signaled interrupts by reusing the
  generic header file

Linus,

The following changes since commit 6fbc7275c7a9ba97877050335f290341a1fd8dbf:

  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
