Text that suggests setting the BB_NUMBER_THREADS and
PARALLEL_MAKE variables to speed build time has been updated to
suggest a setting of twice the number of host cores supported.
The 2x number came to light through a discussion on the project
mailing list initiated by Robert P. J. Day.

Several notes were not producing a line-break betweent he end
of the note and the start of the next paragraph. Most work, but
for some reason these did not. It is a mystery to me.

I had to add some changes to the way we invoke qemu to show multiple
processor support. I needed the qemuparam "-smp 2". There are
other minor edits as well.

I made a pass through the book to clean up all areas in preparation to
running the examples again. Most changes were punctuation, manual
section reference formats, and wordings.

There is an example whose output exceeds the PDF manual version's
page width. I had to artificially break the line up.

Dave Stewart said that good coding practice is to set the variables
before any print statements. So I moved one statement above the
example printk statements.

this example uses the CONFIG_SMP configuration. By default, this configuration is
disabled. The example shows how to use menuconfig and explains the .config file
role and how you can use it combined with menuconfig to manage multiple configuration
changes.
Thanks to Darren Hart for identifying this simple change to demonstrate how to
change the kernel configuration.

Bruce Ashfield's review comments indicated that we will be using
linux-yocto-3.0 and not linux-yocto-2.6.37. So I am putting these
changes in to anticipate the 1.1 release.

There are some issues with the fact that the build process parses
all kernel .bbappend files whether they are used or not during the
build process. I added an extra build configuration note regarding
editing the .bbappend file. I noted that you either have to edit
every .bbappend file and comment out the COMPATIBLE_MACHINE statement
or simply remove all the kernel recipe append files except the one
you are interested in.

I performed a major re-write of this section that touched all
aspects of it. This was necessary due to the fact I could not get
the example running because of not understanding the repo location
and branch needs to set it up.
