333 can simulate a MIPS32 4Kc system. This patch adds support for the
334 system architecture that currently is being simulated by Qemu. It
335 will eventually be removed again when Qemu has the capability to
336 simulate actual MIPS hardware platforms. More information on Qemu
337 can be found at http://www.linux-mips.org/wiki/Qemu.

965 Please make sure to pick the right CPU type. Linux/MIPS is not
966 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
967 *not* work on R4000 machines and vice versa. However, since most
968 of the supported machines have an R4000 (or similar) CPU, R4x00
969 might be a safe bet. If the resulting kernel does not work,
970 try to recompile with R3000.

1405 Enables SMP IRQ affinity API (/proc/irq/*/smp_affinity, etc.)
1406 for SMTC Linux kernel. Requires platform support, of which
1407 an example can be found in the MIPS kernel i8259 and Malta
1408 platform code. It is recommended that MIPS_MT_SMTC_INSTANT_REPLAY
1409 be enabled if MIPS_MT_SMTC_IRQAFF is used. Adds overhead to
1410 interrupt dispatch, and should be used only if you know what
1411 you are doing.
