Merge tag 'riscv-for-linus-5.17-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

Pull RISC-V fixes from Palmer Dabbelt:

 - Fixes for a handful of KASAN-related crashes.

 - A fix to avoid a crash during boot for SPARSEMEM &&
   !SPARSEMEM_VMEMMAP configurations.

 - A fix to stop reporting some incorrect errors under DEBUG_VIRTUAL.

 - A fix for the K210's device tree to properly populate the interrupt
   map, so hart1 will get interrupts again.
