New and rewritten pages
-----------------------

getcpu.2
    Andi Kleen, with some text and edits by mtk
        Documents the getcpu(2) system call, introduced in Linux 2.6.19.

sched_getcpu.3
    mtk
        Documents sched_getcpu(3), a wrapper for getcpu(2), provided
        since glibc 2.6.

cpuset.7
    Paul Jackson, with review and editing by mtk, and comments by
    Hidetoshi Seto and Li Zefan
        A description of the cpuset file system, the mechanism introduced
        kernel 2.6.12 for confining processes to designated processors
        and nodes.  (Becomes the fourth largest page in man-pages!)


Newly documented interfaces in existing pages
---------------------------------------------

readdir.3
    mtk
        Add documentation of readdir_r().


New links

        Link to updwtmp.3 (3.02 changelog wrongly said this had been done).

Changes to individual pages
---------------------------

accept.2
    mtk
        Small wording change.

io_getevents.2
    mtk
        ERRORS: Add EINTR error.

open.2
    mtk
        ERRORS: Add EINTR error.

sigaction.2
    mtk
        Note circumstances in which each SA_* flag is meaningful.
    mtk
        Describe POSIX specification, and Linux semantics for
        SA_NOCLDWAIT when establishing a handler for SIGCHLD.
    mtk
        Add pointer under SA_RESTART to new text in signal(7)
        describing system call restarting.
    mtk
        Other minor edits.

truncate.2
    mtk
        ERRORS: Added EINTR error.
        A few minor rewordings.

wait.2
    mtk
        Remove statement that WUNTRACED and WCONTINUED only have effect
        if SA_NOCLDSTOP has not been set for SIGCHLD.  That's not true.

errno.3
    mtk
        Add a pointer to signal(7) for further explanation of EINTR.

getgrouplist.3
    mtk
        SEE ALSO: Add passwd(5).

readdir.3
    mtk
        Remove <sys/types.h> from SYNOPSIS; POSIX.1-2001 does not
        require it.
        Some minor rewordings.

sleep.3
    mtk
        RETURN VALUE: explicitly mention interruption by signal handler.
        SEE ALSO: add signal(7).

usleep.3
    mtk
        POSIX.1-2001 also does not document EINVAL.

group.5
    mtk
        SEE ALSO: Add getgrent(3), getgrnam(3).

passwd.5
    mtk
        SEE ALSO: Add getpwent(3), getpwnam(3).

proc.5
    mtk
        Add pointer to description of /proc/PID/cpuset in cpuset(7).

signal.7
    mtk
        Add a section describing system call restarting, and noting
        which system calls are affected by SA_RESTART, and which
        system calls are never restarted.
    mtk
        Describe the aberrant Linux behavior whereby a stop signal
        plus SIGCONT can interrupt some system calls, even if no
        signal handler has been established, and note the system
        calls that behave this way.
    mtk
        Note a few more architectures on which signal numbers are valid.
        SEE ALSO: added a number of pages.
    mtk
        Update async-signal-safe function list for POSIX.1-2004 (which
        adds sockatmark()).
