    Patch in this message
    Subject/proc 2.6.24 changes for guest CPU accounting
    Hi Laurent,

    A note and patch from Samuel alerted me to your commits
    9ac52315d4cf5f561f36dabaf0720c00d3553162 and
    5e84cfde51cf303d368fcb48f22059f37b3872de, which in 2.6.24 changed /proc/stat
    and /proc/PID/stat. Would you please CC me on kernel-userspace interface
    changes, so that they have a chance of getting documented in man-pages.

    (I see that Andrew P tried to get something added to
    Documentation/filesystems/proc.txt, but that doesn't seem to have made it in.)

    Below is a patch against the proc.5 man page by Samuel and I to document these
    changes. Do the changes look okay to you? The first part is the change for
    /proc/<pid>/stat, and the other is for /proc/stat.
