  riscv: remove address space overrides using set_fs() (2020-10-04 10:27:10 -0700)

----------------------------------------------------------------
RISC-V Patches for the 5.10 Merge Window, Part 2

This actually just contains a single patch set:

* The remainder of Christoph's work to remove set_fs, including the RISC-V
  portion.

----------------------------------------------------------------
I know I said in the previous PR that I'd keep including shortlogs as of the
last tag, but I haven't done that here as it would include my previous PR.
Essentially I wanted to wait for the base branch of this to land first, as it
touched a lot.  Rather than rebasing I've just left the original merge in
place and sent a shortlog against master.

I'm not sure why the diffstat shows so much more, though.  I manually checked
the commits and my merge has the same commits yours does.  It's my first time
trying this particular sort of merge (though the last one had a tag-based merge
of the same sort, which IIUC shouldn't be any different) so hopefully it went
OK.

Christoph Hellwig (8):
      uaccess: provide a generic TASK_SIZE_MAX definition
      asm-generic: improve the nommu {get,put}_user handling
      asm-generic: add nommu implementations of __{get,put}_kernel_nofault
      asm-generic: make the set_fs implementation optional
      riscv: use memcpy based uaccess for nommu again
      riscv: refactor __get_user and __put_user
      riscv: implement __get_kernel_nofault and __put_user_nofault
      riscv: remove address space overrides using set_fs()

Palmer Dabbelt (1):
      Merge branch 'base.set_fs' of git://git.kernel.org/.../viro/vfs into for-next
