This option configures this kernel to be linked at a different address and use the 2nd uart for output. This allows a kernel built with this option to be run at the same time as one built without this option.
Configure the Octeon hardware to automatically fix unaligned loads and stores. Normally unaligned accesses are fixed using a kernel exception handler. This option enables the hardware automatic fixups, which requires only an extra 3 cycles. Disable this option if you are running code that relies on address exceptions on unaligned accesses.
CVMSEG LM is a segment that accesses portions of the dcache as a local memory; the larger CVMSEG is, the smaller the cache is. This selects the size of CVMSEG LM, which is in cache blocks. The legally range is from zero to 54 cache blocks (i.e. CVMSEG LM is between zero and 6192 bytes).
Enable locking parts of the kernel into the L2 cache.
Lock the low level TLB fast path into L2.
Lock the low level exception handler into L2.
Lock the low level interrupt handler into L2.
Lock the 2nd level interrupt handler in L2.
Lock the kernel's implementation of memcpy() into L2.
