CPUs can be - controlled through /sys/devices/system/cpu. - - Say N if you want to disable CPU hotplug. - -config HIGHMEM - bool "High Memory Support" - help - The address space of Meta processors is only 4 Gigabytes large - and it has to accommodate user address space, kernel address - space as well as some memory mapped IO. That means that, if you - have a large amount of physical memory and/or IO, not all of the - memory can be "permanently mapped" by the kernel.

LNKGET/LNKSET are load-link/store-conditional instructions. - Choose this option if your system requires low latency. - -config METAG_ATOMICITY_LOCK1 - depends on SMP - bool "lock1" - help - This option uses the LOCK1 instruction for atomicity.
