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 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
