Merge tag 'riscv-for-linus-6.19-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

Pull RISC-V updates from Paul Walmsley:

 - Enable parallel hotplug for RISC-V

 - Optimize vector regset allocation for ptrace()

 - Add a kernel selftest for the vector ptrace interface

 - Enable the userspace RAID6 test to build and run using RISC-V vectors

 - Add initial support for the Zalasr RISC-V ratified ISA extension

 - For the Zicbop RISC-V ratified ISA extension to userspace, expose
   hardware and kernel support to userspace and add a kselftest for
   Zicbop

 - Convert open-coded instances of 'asm goto's that are controlled by
   runtime ALTERNATIVEs to use riscv_has_extension_{un,}likely(),
   following arm64's alternative_has_cap_{un,}likely()

 - Remove an unnecessary mask in the GFP flags used in some calls to
   pagetable_alloc()
