Trouble is that NR_CPUS is used all over the place. If nr_cpu_ids < NR_CPUS at boot then there is a danger of for loops to NR_CPUS going out of bounds.
CONFIG_NR_CPUS is used for various bitmaps so that seems to be okay.
drivers/acpi/numa.c:acpi_numa_init probably should use nr_cpu_ids instead now.
There is an octeon driver in staging that has some issues with NR_CPUS as well.
