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
