The shared cache info for s390 can be found in /proc/cpuinfo.
lscpu without any options already processes this info. Fix this
in lscpu -C and provide detailed stat.

Commit 7a2602f629 ("blkzone: deny destructive ioctls on busy blockdev")
introduced exclusive mode to open block devices to submit zone management
ioctls. This avoids unintended status change of block devices used by the
system. However, it makes blkzone less usable for testing. For example,
the test case zbd/007 of blktests utilizes blkzone to reset zones of
block devices mapped to dm-linear devices. After the commit, the test
case fails with EBUSY error at blkzone reset, since the system uses the
reset target block device to map to the dm-linear device.
To allow blkzone to change status of zoned block devices used by the
system with intention, introduce --force option. With this option, block
devices are opened without exclusive mode.
Also fix too many periods in man page of --verbose option.

Timestamps in kernel log comes from monotonic clocksource which does not
tick when system suspended. Suspended time easily sums into hours and days
rendering human readable timestamps in dmesg useless.
Adjusting timestamps accouring to current delta between boottime and
monotonic clocksources produces accurate timestamps for messages printed
since last resume. Which are supposed to be most interesting.

Attempting to create a persistent PID namespace with --pid=<file>
will result in an error if --fork is not also specified. Let's
warn people about that, so they don't get puzzled.

The existing text is not quite accurate, and I recently injected an
error into the EXAMPLES. This patch fixes both issues.
The text in DESCRIPTION incorrectly states that the propagation type of
the parent mount must be "private". This is not accurate. Rather, the
propagation type must be something *other than "shared"* (i.e.,
"private", "slave", or "unbindable").
In the EXAMPLES section, I added text that implies that if the
propagation type of the parent mount is "shared", then the child mount
created by --mount=<path> might propagate to another namespace.
Rather, in this situation, an error would result. Clarify that.

This patch add support for a new tag. The tag is based on udev block
device ID (see /dev/disk/by-id). The usual use-case is to use
WWN for this purpose, for example
# mount ID=wwn-0x50026b724b09a1ff /mnt
Note that ID is not strictly defined and udevd generates various IDs
also for HW where WWN is undefined. This is reason why introduce ID=
seems better and more generic than more restrictive WWN=.

Option --follow-new (-W) works the same as --follow (-w) but initially
seeks to the end of kernel ring buffer, so it prints only new messages.
Useful for capturing kernel messages during actions without past log.

In several pages, there is a consistent wording problem: "another"
where "other" should be used. This wording problem can be
surprisingly confusing for native speakers, especially those
unaware that in some other languages, "another" and "other" can be
expressed with the same word.

A while ago stdout and stderr have been split in these testcases, but
"FATAL: kernel too old" is actually treated as an "okay" output. However
this FATAL ends up on stderr, so when it happens, it is not seen in
the captured stdout.
Fix this by merging stdout/stderr in these cases once again.

Earlier, I patched various pages to consistently use EXAMPLE as a
section heading, rather than EXAMPLES. (At that time, both headings
occurred in util-linux, with roughly equal frequency.)
Since then, I've observed that EXAMPLES is the more common usage
across a large corpus of manual pages. So, in Linux the man-pages
project, I switched to using EXAMPLES also. This patch makes the same
change for util-linux.

The current code hides details about reason why swapoff(8) and swapoff(2) failed. For example
ENOMEM from swapoff(2) is important as it indicates OOM.
The patch also clean ups --all return codes to be more compatible for
example with [u]mount --all, etc.
