Kconfig: update flightly outdated CONFIG_SMP documentation
Browse files Browse the repository at this point in the history 
Remove an outdated reference to "most personal computers" having only one
CPU, and change the use of "singleprocessor" and "single processor" in
CONFIG_SMP's documentation to "uniprocessor" across all arches where that
documentation is present.
