Merge tag 'riscv-for-linus-5.14-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull RISC-V fixes from Palmer Dabbelt:
- device tree updates for the Microsemi Polarfire development kit that
fix some mismatches between the u-boot and Linux enternet entries
- ensure that the F register state is correctly reflected in core dumps
* tag 'riscv-for-linus-5.14-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux:
riscv: dts: microchip: Add ethernet0 to the aliases node
riscv: dts: microchip: Use 'local-mac-address' for emac1
riscv: Ensure the value of FP registers in the core dump file is up to date
