Merge tag 'riscv-for-linus-5.18-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull RISC-V updates from Palmer Dabbelt: - Support for Sv57-based virtual memory. - Various improvements for the MicroChip PolarFire SOC and the associated Icicle dev board, which should allow upstream kernels to boot without any additional modifications. - An improved memmove() implementation. - Support for the new Ssconfpmf and SBI PMU extensions, which allows for a much more useful perf implementation on RISC-V systems. - Support for restartable sequences. * tag 'riscv-for-linus-5.18-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: (36 commits) rseq/selftests: Add support for RISC-V RISC-V: Add support for restartable sequence MAINTAINERS: Add entry for RISC-V PMU drivers Documentation: riscv: Remove the old documentation RISC-V: Add sscofpmf extension support RISC-V: Add perf platform driver based on SBI PMU extension RISC-V: Add RISC-V SBI PMU extension definitions RISC-V: Add a simple platform driver for RISC-V legacy perf RISC-V: Add a perf core library for pmu drivers RISC-V: Add CSR encodings for all HPMCOUNTERS RISC-V: Remove the current perf implementation RISC-V: Improve /proc/cpuinfo output for ISA extensions RISC-V: Do no continue isa string parsing without correct XLEN RISC-V: Implement multi-letter ISA extension probing framework RISC-V: Extract multi-letter extension names from "riscv, isa" RISC-V: Minimal parser for "riscv, isa" strings RISC-V: Correctly print supported extensions riscv: Fixed misaligned memory access.

+description: |
+ PolarFire SoC devices include a microcontroller acting as the system controller,
+ which provides "services" to the main processor and to the FPGA fabric. These
+ services include hardware rng, reprogramming of the FPGA and verfification of the
+ eNVM contents etc. More information on these services can be found online, at
+ https://onlinedocs.microchip.com/pr/GUID-1409CF11-8EF9-4C24-A94E-70979A688632-en-US-1/index.html
+
+ Communication with the system controller is done via a mailbox, of which the client
+ portion is documented here.
