Pull more RISC-V updates from Palmer Dabbelt: - Support for sv48 paging - Hart ID mappings are now sparse, which enables more CPUs to come up on systems with sparse hart IDs - A handful of cleanups and fixes * tag 'riscv-for-linus-5.17-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: (27 commits) RISC-V: nommu_virt: Drop unused SLAB_MERGE_DEFAULT RISC-V: Remove redundant err variable riscv: dts: sifive unmatched: Add gpio poweroff riscv: canaan: remove useless select of non-existing config SYSCON RISC-V: Do not use cpumask data structure for hartid bitmap RISC-V: Move spinwait booting method to its own config RISC-V: Move the entire hart selection via lottery to SMP RISC-V: Use __cpu_up_stack/task_pointer only for spinwait method RISC-V: Do not print the SBI version during HSM extension boot print RISC-V: Avoid using per cpu array for ordered booting riscv: default to CONFIG_RISCV_SBI_V01=n riscv: fix boolconv.cocci warnings riscv: Explicit comment about user virtual address space size riscv: Use pgtable_l4_enabled to output mmu_type in cpuinfo riscv: Implement sv48 support asm-generic: Prepare for riscv use of pud_alloc_one and pud_free riscv: Allow to dynamically define VA_BITS riscv: Introduce functions to switch pt_ops riscv: Split early kasan mapping to prepare sv48 introduction riscv: Move KASAN mapping next to the kernel mapping ...
