OK, here's a preliminary infrastructure patch for statfs64 and
fstatfs64. Patch against yesterday's BK tree.

I've implemented it only for IA64 and i386, because that's all I can
test --- it's fairly trivial to add the system calls for other
architectures, though.

What I've done is primarily to isolate the internal form of struct
statfs from what's handed out to users.

Still to do is any file-system specific stuff (to implement f_frsize,
to do anything special that's needed for large filesystem support) and
of course the other architectures.

I didn't add a passed-in argument of expected size, as I think that
statfs64 is well enough understood (and there are 5 spare longs
anyway).

# The following is the BitKeeper ChangeSet Log
# --------------------------------------------
# 02/10/18 peterc@gelato.unsw.edu.au 1.792
# Implement statfs64 and fstatfs64 for IA64 and I386. (Other architectures later, if this
# passes peer review).
#
# -- Add a new type struct kstatfs that is variable sized depending on CONFIG_LBD.
# This type is used for all in-kernel communication between filesystems and the system
# calls.
# -- Convert to the user-expected form in the system call code.
#
# Todo:
# -- Add support for new field, f_frsize in each filesystem
# -- Add support for other architectures.
# -- (Maybe) move struct statfs to asm-generic
# --------------------------------------------
