Message:

IPRT/r0drv/mp-r0drv-linux.c: Use version checks for linux/cpumask.h stuff rather than assuming that everything in it will remain macros forever (num_online_cpus isn't anymore). Fixed possible bug in RTMpGetCount where it wouldn't handle CPU hotplugging right. [corrected nr_cpumask_bits version from 2.6.27 to 2.6.28]
