1147 Please make sure to pick the right CPU type. Linux/MIPS is not
1148 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1149 *not* work on R4000 machines and vice versa. However, since most
1150 of the supported machines have an R4000 (or similar) CPU, R4x00
1151 might be a safe bet. If the resulting kernel does not work,
1152 try to recompile with R3000.

1902 This allows you to specify the maximum number of CPUs which this
1903 kernel will support. The maximum supported value is 32 for 32-bit
1904 kernel and 64 for 64-bit kernels; the minimum value which makes

1905 sense is 1 for Qemu (useful only for kernel debugging purposes)
1906 and 2 for all others.

1908 This is purely to save memory - each supported CPU adds

1909 approximately eight kilobytes to the kernel image. For best
1910 performance should round up your number of processors to the next
1911 power of two.

2024 syscalls, it's possible to isolate those applications in
