Merge tag 'riscv/for-v5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull RISC-V updates from Paul Walmsley: "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" * tag 'riscv/for-v5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: (22 commits) riscv: provide a flat image loader riscv: add nommu support riscv: clear the instruction cache and all registers when booting riscv: read the hart ID from mhartid on boot riscv: provide native clint access for M-mode riscv: dts: add support for PDMA device of HiFive Unleashed Rev A00 riscv: add support for MMIO access to the timer registers riscv: implement remote sfence.i using IPIs riscv: cleanup the default power off implementation riscv: poison SBI calls for M-mode riscv: don't allow selecting SBI based drivers for M-mode RISC-V: Add multiple compression image format. riscv: clean up the macro format in each header file riscv: Use PMD_SIZE to replace PTE_PARENT_SIZE riscv: abstract out CSR names for supervisor vs machine mode riscv: separate MMIO functions into their own header file riscv: enter WFI in default_power_off() if SBI does not shutdown RISC-V: Issue a tlb page flush if possible RISC-V: Issue a local tlbflush if possible. RISC-V: Do not invoke SBI call if cpumask is empty ...
