Merge tag 'riscv-for-linus-5.15-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull RISC-V updates from Palmer Dabbelt:
- support PC-relative instructions (auipc and branches) in kprobes
- support for forced IRQ threading
- support for the hlt/nohlt kernel command line options, via the
generic idle loop
- show the edge/level triggered behavior of interrupts
in /proc/interrupts
- a handful of cleanups to our address mapping mechanisms
- support for allocating gigantic hugepages via CMA
- support for the undefined behavior sanitizer (UBSAN)
- a handful of cleanups to the VDSO that allow the kernel to build with
LLD.
- support for hugepage migration
