Hi All,
The latest mainline kernel branch fails to build for "arm allmodconfig",
"xtensa allmodconfig" and "csky allmodconfig" with the error:
In file included from ./include/linux/kernel.h:26,

git bisect pointed to 6c77676645ad ("iov_iter: Fix iter_xarray_get_pages{,_alloc}()")
And, reverting it on top of mainline branch has fixed the build failure.
