This allows a hyphenated range of positive numbers in the string passed
to command line helper function, get_options.
Currently the command line option "isolcpus=" takes as its argument a
list of cpus.
Format: <cpu number>,...,<cpu number>
Valid values of <cpu_number> include all cpus, 0 to "number of CPUs in
system - 1". This can get extremely long when isolating the majority of
cpus on a large system. The kernel isolcpus code would not need any
changing to use this feature. To use it, the change would be in the
command line format for 'isolcpus='
Format:
<cpu number>,...,<cpu number>
or
<cpu number>-<cpu number> (must be a positive range in ascending
order.)
or a mixture
<cpu number>,...,<cpu number>-<cpu number>

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
