As previously discussed[2] this patchset implements proposal "2a" and does the following: * marks the old coremask parameter (-c) and service core mask (-s) as deprecated, so they can be dropped in future. Everything should now be done using core lists where possible. * consolidates the, previously separate but similar, "-l" and "--lcores" flags into just short and long versions of the same thing. This does not affect the "--lcores" flag at all, but expands the scope of what was possible with "-l". * a new flag, with long/short versions, is added as "-L" to allow the user to just specify a range or set of physical CPU core ids to be used by the app, and have them automatically mapped internally to a set of lcore ids starting at 0. This provides the "easy solution" to the original problem stated above. For completeness, since it's in the same area, the previously separate documentation patch, adding examples for the "--lcores" parameter, is rolled into this series as patch 3.
