[PATCH] Ignore bogus ACPI info for offline CPUs
Booting a SMP kernel with maxcpus=1 on a SMP system leads to a hard
hang, because ACPI ignores the maxcpus setting and sends timer broadcast
info for the offline CPUs. This results in a stuck for ever call to
smp_call_function_single() on an offline CPU.
Ignore the bogus information and print a kernel error to remind ACPI
folks to fix it.
Affects 2.6.21 / 2.6.22-rc
