Use require instead of include to avoid silent errors when the required
tune files change name or are moved. It's going to fail anyway, it might
as well fail with an error message that is immediately helpful.

Aside from the movbe and specialized instruction scheduling for the lack
of out-of-order scheduling in the older Atom CPUs, the core2 tune covers
these CPUs adequately. Since the current atom tune just uses core2
anyway, go ahead and make this explicit here.

Its rather sad that people don't appear to read local.conf and then complain
about slow builds when they're just using a single thread. Most systems have
more than one core now so we might as well use a more automatic default
for these values. This may lead to better experiences for new users.

The tune-x86_64.inc file is conceptually flawed. x86_64 is more akin to
the x86 and x86-32 ABIs defined in arch-x86.inc than it is a concrete
tune file, such as i586 or core2 - to the extent that everything but the
default tune is defined in the arch-x86.inc file. This becomes very
apparant when attempting to include tune-x86_64.inc in the x86 tune
hierarchy.
Remove the tune-x86_64.inc tune file in favor of it being an ABI
definition in arch-x86.inc and relying on the linear hierarchy of
concrete cpu-types in tune-i586, tune-core2, and tune-corei7.
core2_64 should suffice in lieu of x86_64 for all but a couple esoteric
corner cases involving older pre-core2 CPUs. In these cases, if they
exist at all, the BSP can replace the include tune-x86_64.inc with
arch-x86.inc and set the default tune to x86_64.

From the GCC(1):
Intel Core i7 CPU with 64-bit extensions, MMX, SSE, SSE2, SSE3,
SSSE3, SSE4.1 and SSE4.2 instruction set support.
This offers optimizations for Nehalem and Silvermont (e.g. Bay Trail)
CPUs (and beyond).

Core2 has both a 32b and a 64b variant. Currently, core2 implies 32b,
while core2_64 is the 64b version. This implicit 32b mode will become
confusing in later architectures, such as corei7, where it would be
natural for people to assume "corei7" meant 64 bit.
Rather than carrying forward an implicit 32b mode and rather than
changing the naming scheme part way through the architecture hiearchy,
make the 32b and 64b variant explicit in the tune name by changing core2
to core2-32. This patch also standardises on using '-' in the names.

-march specifies which ISA to use. -mtune specifies which cpu-type to
optimize instruction ordering for, but not which ISA to use. There are
times when it may make sense to specify mtune=generic and use a more
specific march, such as core2, but the opposite makes little sense at
all: use cpu-type specific ISA, but order the instructions
generically. While the -mtune is implied by -march, gcc does not verify
it is using -mtune=core2 with:
gcc -Q -march=core2 --help=target
Explicitly specify -mtune=core2 to be sure.
Add a comment header describing the CPUs targeted by this tune file.

The generic x86 build supports i586 by default, so this specific tune
file technically doesn't add any specific ARCHes to PACKAGE_EXTRA_ARCHS.
For consistency, append the current tune to PACKAGE_EXTRA_ARCHS.
Since we do not have specific tune files for i386 and i486, just drop
them.
These could be added to tune-x86 version if there is a need to
maintain them, but they really do not belong here.

ia32 implies 32bit, while these files provide descriptions for IA32,
X86_64, and X32 architectures. The term "x86" fits this used better
without resorting to using the term "Intel" which isn't quite right as
it excludes things like the tune-c3 file describing a Via CPU.

for getting the book's title to format onto the title page.
Commenting the code out suppresses the title from the

is because the BitBake User Manual uses an image file for
the title. Thus, it is not necessary to print the title
