Pull arm64 fixes from Catalin Marinas:
 "Most of issues addressed were introduced during this merging window.

   - Initialise jump labels before setup_machine_fdt(), needed by commit
     f5bda35 ("random: use static branch for crng_ready()").

   - Sparse warnings: missing prototype, incorrect __user annotation.

   - Skip SVE kselftest if not sufficient vector lengths supported"
