Pull more RISC-V updates from Palmer Dabbelt: "Just a single patch set: the remainder of Christoph's work to remove set_fs, including the RISC-V portion" * tag 'riscv-for-linus-5.10-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: riscv: remove address space overrides using set_fs() riscv: implement __get_kernel_nofault and __put_user_nofault riscv: refactor __get_user and __put_user riscv: use memcpy based uaccess for nommu again asm-generic: make the set_fs implementation optional asm-generic: add nommu implementations of __{get,put}_kernel_nofault asm-generic: improve the nommu {get,put}_user handling uaccess: provide a generic TASK_SIZE_MAX definition
