Provides a mask of CPUs which irqbalance should ignore and never assign interrupts to.
If not specified, irqbalance use mask of isolated and adaptive-ticks CPUs on the
system as the default value.
This is a hexmask without the leading ’0x’. On systems with large numbers of
processors, each group of eight hex digits is separated by a comma ’,’. i.e.
‘export IRQBALANCE_BANNED_CPUS=fc0‘ would prevent irqbalance from assigning irqs
to the 7th-12th cpus (cpu6-cpu11) or ‘export IRQBALANCE_BANNED_CPUS=ff000000,00000001‘
would prevent irqbalance from assigning irqs to the 1st (cpu0) and 57th-64th cpus
(cpu56-cpu63).
