These days 4 kilobytes of stack just aren't enough for reliably operation,
and people using lots of threads have long switched to 64-bit kernels, so
remove the CONFIG_4KSTACKS option.

Add another option when selecting CPU family so the kernel can be
optimized for Intel Atom CPUs. If GCC supports tuning options for
Intel Atom they will be used.

All files that have been made identical to the asm-generic
version in the previous patches can now be removed,
guaranteeing that this does not introduce semantic changes.

In x86, mman.h, module.h, scatterlist.h, types.h and ucontext.h
can use the asm-generic version by just defining the x86
specific parts locally and falling back on the generic code
for the common bits.
This patch illustrates the differences between the x86 and
asm-generic versions by changing a file that is initially
identical to the x86 version to one that is identical
to the asm-generic version.

Change header guards named "ASM_X86__*" to "_ASM_X86_*" since:
a. the double underscore is ugly and pointless.
b. no leading underscore violates namespace constraints.
