  Merge branch 'next/nommu' into for-next (2019-11-22 18:59:09 -0800)

----------------------------------------------------------------
First set of RISC-V updates for v5.5-rc1

New features:

- SECCOMP support

- nommu support

- SBI-less system support

- M-Mode support

- TLB flush optimizations

Other improvements:

- Pass the complete RISC-V ISA string supported by the CPU cores to
  userspace, rather than redacting parts of it in the kernel

- Add platform DMA IP block data to the HiFive Unleashed board DT file

- Add Makefile support for BZ2, LZ4, LZMA, LZO kernel image
  compression formats, in line with other architectures

Cleanups:

- Remove unnecessary PTE_PARENT_SIZE macro

- Standardize include guard naming across arch/riscv

----------------------------------------------------------------
Atish Patra (5):
      RISC-V: Remove unsupported isa string info print
      RISC-V: Do not invoke SBI call if cpumask is empty
      RISC-V: Issue a local tlbflush if possible.
      RISC-V: Issue a tlb page flush if possible
      RISC-V: Add multiple compression image format.

Christoph Hellwig (10):
      riscv: enter WFI in default_power_off() if SBI does not shutdown
      riscv: abstract out CSR names for supervisor vs machine mode
      riscv: poison SBI calls for M-mode
      riscv: cleanup the default power off implementation
      riscv: implement remote sfence.i using IPIs
      riscv: add support for MMIO access to the timer registers
      riscv: provide native clint access for M-mode
      riscv: clear the instruction cache and all registers when booting
      riscv: add nommu support
      riscv: provide a flat image loader

Damien Le Moal (2):
      riscv: don't allow selecting SBI based drivers for M-mode
      riscv: read the hart ID from mhartid on boot

David Abdurachmanov (1):
      riscv: add support for SECCOMP and SECCOMP_FILTER

Green Wan (1):
      riscv: dts: add support for PDMA device of HiFive Unleashed Rev A00

Paul Walmsley (6):
      riscv: separate MMIO functions into their own header file
      Merge branch 'next/seccomp' into for-next
      Merge branch 'next/isa-string' into for-next
      Merge branch 'next/tlb-opt' into for-next
      Merge branch 'next/misc' into for-next
      Merge branch 'next/nommu' into for-next

Zong Li (2):
      riscv: Use PMD_SIZE to replace PTE_PARENT_SIZE
      riscv: clean up the macro format in each header file
