914 Say Y here to allow turning CPUs off and on. CPUs can be
915 controlled through /sys/devices/system/cpu.
916 (Note: power management support will enable this option
917 automatically on SMP systems. )
918 Say N if you want to disable CPU hotplug.

970 Some MIPS machines can be configured for either little or big endian
5e83d430 971 byte order. These modes require different kernels and a different
3cb2fccc 972 Linux distribution. In general there is one preferred byteorder for a
5e83d430 973 particular system but some systems are just as commonly used in the
3dde6ad8 974 one or the other endianness.

1814 This is a kernel model which is known a VSMP but lately has been
1815 marketesed into SMVP.
1816 Virtual SMP uses the processor's VPEs to implement virtual
1817 processors. In currently available configuration of the 34K processor
1818 this allows for a dual processor. Both processors will share the same
1819 primary caches; each will obtain the half of the TLB for it's own
1820 exclusive use. For a layman this model can be described as similar to
1821 what Intel calls Hyperthreading.

1840 is presenting the available TC's of the core as processors to Linux.
1841 On currently available 34K processors this means a Linux system will

1843 significantly from VSMP and cannot efficiently coexist in the same
