Hi Al and Linus,
currently a lot of the file system calls in the early in code (and the
devtmpfs kthread) rely on the implicit set_fs(KERNEL_DS) during boot.
This is one of the few last remaining places we need to deal with to kill
off set_fs entirely, so this series adds new helpers that take kernel
pointers. These helpers are in init/ and marked __init and thus will
be discarded after bootup. A few also need to be duplicated in devtmpfs,
though unfortunately.
The series sits on top of my previous
"decruft the early init / initrd / initramfs code v2"
series.

Changes since v2:
- move to fs/for-init.c
- reuse the init routines in devtmpfs after refactoring devtmpfsd
(and thus the broken error handling in the previous version)
- actually use kern_path in a place where user_path_at sneaked back in
Changes since v1:
- avoid most core VFS changes
- renamed the functions and move them to init/ and devtmpfs
- drop a bunch of cleanups that can be submitted independently now
