Subject: linux-next: build warnings after merge of the block tree

Hi all,

After merging the block tree, today's linux-next build (x86_64
allnoconfig) produced these warnings:

lib/iov_iter.o: warning: objtool: .altinstr_replacement+0x0: redundant UACCESS d
isable
lib/iov_iter.o: warning: objtool: iovec_from_user.part.0+0xc7: call to copy_comp
at_iovec_from_user.part.0() with UACCESS enabled
lib/iov_iter.o: warning: objtool: __import_iovec+0x21d: call to copy_compat_iovec_from_user.part.0() with UACCESS enabled

Presumably introduced by commit

  6376ce56feb6 ("iov_iter: import single vector iovecs as ITER_UBUF")

Cheers,
Stephen Rothwell
