Merge tag 'riscv-for-linus-5.17-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

Pull RISC-V updates from Palmer Dabbelt:

 - Support for the DA9063 as used on the HiFive Unmatched.

 - Support for relative extables, which puts us in line with other
   architectures and save some space in vmlinux.

 - A handful of kexec fixes/improvements, including the ability to run
   crash kernels from PCI-addressable memory on the HiFive Unmatched.

 - Support for the SBI SRST extension, which allows systems that do not
   have an explicit driver in Linux to reboot.

 - A handful of fixes and cleanups, including to the defconfigs and
   device trees.
