Ingo points out that I screwed up when merging the 'timers-for-linus'
branch in commit a03fdb7612874834d6847107198712d18b5242c7.
A bit too much copy-and-pasting caused the end result to have an
extraneous 'return' in the middle of an expression. That was obviously
bogus. Blush.

On an AMD-64 system the processor frequency that is printed during
system boot, may be different than the tsc frequency that was
returned by the hypervisor, due to the value returned from
calibrate_cpu.
For debugging timekeeping or other related issues it might be
better to get the tsc_khz value returned by the hypervisor.
The patch below now prints the tsc frequency that the VMware
hypervisor returned.

runqueue_is_locked() is unavoidably racy due to a poor interface design.
It does
cpu = get_cpu()
ret = some_perpcu_thing(cpu);
put_cpu(cpu);
return ret;
Its return value is unreliable.

Tweak the output SVG to increase performance in SVG viewers by

This patch adds a command line option for timechart that allows the
user to specify the width of the SVG file.
This patch also makes sure that each second of recording has at
least 200 units (pixels at 96 DPI) of width. This impacts
recordings longer than 5 seconds; recordings shorter than 5 second
will scale up to have a width of 1000 units for the whole recording
(as before).

This patch (as1292) modifies the USB serial console driver, to make it
compatible with the recent changes to the USB serial core. The most
important change is that serial->disc_mutex now has to be unlocked
following a successful call to usb_serial_get_by_index().
Other less notable changes include:
Use the requested port number instead of port 0 always.
Prevent the serial device from being autosuspended.
Use the ASYNCB_INITIALIZED flag bit to indicate when the
port hardware has been initialized.
In spite of these changes, there's no question that the USB serial
console code is still a big hack.

This patch (as1291) removes a bunch of code from serial_open(), things
that were rendered unnecessary by earlier patches. A missing spinlock
is added to protect port->port.count, which needs to be incremented
even if the open fails but not if the tty has gotten a hangup. The
test for whether the hardware has been initialized, based on the use
count, is replaced by a more transparent test of the
ASYNCB_INITIALIZED bit in the port flags.

This patch (as1290) adds some missing tests. serial_down() isn't
supposed to do anything if the hardware hasn't been initialized, and
serial_close() isn't supposed to do anything if the tty has gotten a
hangup (because serial_hangup() takes care of shutting down the
hardware).
The patch also updates and adds a few debugging lines.
