iov_iter cleanups and fixes; there are followups, but this is what
had sat in -next this cycle. IMO the macro forest in there became much
thinner and easier to follow...
The following changes since commit 6efb943b8616ec53a5e444193dccf1af9ad627b5:
Linux 5.13-rc1 (2021-05-09 14:17:44 -0700)

csum_and_copy_to_pipe_iter(): leave handling of csum_state to caller (2021-06-10 11:45:25 -0400)
----------------------------------------------------------------
Al Viro (36):
ntfs_copy_from_user_iter(): don't bother with copying iov_iter
generic_perform_write()/iomap_write_actor(): saner logics for short copy
fuse_fill_write_pages(): don't bother with iov_iter_single_seg_count()
teach copy_page_to_iter() to handle compound pages
copy_page_to_iter(): fix ITER_DISCARD case
[xarray] iov_iter_fault_in_readable() should do nothing in xarray case
iov_iter_advance(): use consistent semantics for move past the end
iov_iter: switch ..._full() variants of primitives to use of iov_iter_revert()
iov_iter: reorder handling of flavours in primitives
iov_iter_advance(): don't modify ->iov_offset for ITER_DISCARD
iov_iter: separate direction from flavour
iov_iter: optimize iov_iter_advance() for iovec and kvec
sanitize iov_iter_fault_in_readable()
iov_iter_alignment(): don't bother with iterate_all_kinds()
iov_iter_gap_alignment(): get rid of iterate_all_kinds()
get rid of iterate_all_kinds() in iov_iter_get_pages()/iov_iter_get_pages_alloc()
iov_iter_npages(): don't bother with iterate_all_kinds()
[xarray] iov_iter_npages(): just use DIV_ROUND_UP()
iov_iter: replace iov_iter_copy_from_user_atomic() with iterator-advancing variant
csum_and_copy_to_iter(): massage into form closer to csum_and_copy_from_iter()
iterate_and_advance(): get rid of magic in case when n is 0
iov_iter: massage iterate_iovec and iterate_kvec to logics similar to iterate_bvec
iov_iter: unify iterate_iovec and iterate_kvec
iterate_bvec(): expand bvec.h macro forest, massage a bit
iov_iter: teach iterate_{bvec,xarray}() about possible short copies
iov_iter: get rid of separate bvec and xarray callbacks
iov_iter: make the amount already copied available to iterator callbacks
iov_iter: make iterator callbacks use base and len instead of iovec
pull handling of ->iov_offset into iterate_{iovec,bvec,xarray}
iterate_xarray(): only of the first iteration we might get offset != 0
copy_page_to_iter(): don't bother with kmap_atomic() for bvec/kvec cases
copy_page_from_iter(): don't need kmap_atomic() for kvec/bvec cases
iov_iter: clean csum_and_copy_...() primitives up a bit
pipe_zero(): we don't need no stinkin' kmap_atomic()...
clean up copy_mc_pipe_to_iter()
csum_and_copy_to_pipe_iter(): leave handling of csum_state to caller
David Howells (1):
iov_iter: Remove iov_iter_for_each_range()
