The nommu code has regressed somewhat in that 29BIT gets set for the SH-2/2A configs regardless of the fact that they are really 32BIT sans MMU or PMB. This does a bit of tidying to get nommu properly selecting 32BIT as it was before. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

This adds the cpufreq driver for SuperH. Any CPU that supports
|
|
clock rate rounding through the clock framework can use this
|
|
driver. While it will make the kernel slightly larger, this is
|
|
harmless for CPUs that don't support rate rounding. The driver
|
|
will also generate a notice in the boot log before disabling
|
|
itself if the CPU in question is not capable of rate rounding.
|

|
|
kexec is a system call that implements the ability to shutdown your
|
|
current kernel, and to start another kernel. It is like a reboot
|
|
but it is independent of the system firmware. And like a reboot
|
|
you can start any kernel with it, not just Linux.
|
|
|
|
The name comes from the similarity to the exec system call.
|
|
|
|
It is an ongoing process to be certain the hardware in a machine
|
|
is properly shutdown, so do not be surprised if this code does not
|
|
initially work for you. It may help to enable device hotplugging
|
|
support. As of this writing the exact hardware interface is
|
|
strongly in flux, so no good recommendation can be made.

Generate crash dump after being started by kexec.

which are loaded in the main kernel with kexec-tools into

a specially reserved region and then later executed after

a crash by kdump/kexec. The crash dump kernel must be compiled

to a memory address not used by the main kernel using

MEMORY_START.

This kernel feature is useful for number crunching applications

that may need to compute untrusted bytecode during their
|
|
execution. By using pipes or other transports made available to
|
|
the process as file descriptors supporting the read/write
|
|
syscalls, it's possible to isolate those applications in
|
|
their own address space using seccomp. Once seccomp is

|
enabled via prctl, it cannot be disabled and the task is only

allowed to execute a few safe syscalls defined by each seccomp

mode.

This enables support for systems with more than one CPU. If you have

a system with only one CPU, like most personal computers, say N. If

you have a system with more than one CPU, say Y.
|

If you say N here, the kernel will run on single and multiprocessor
|
|
machines, but will use only one CPU of a multiprocessor machine. If

you say Y here, the kernel will run on many, but not all,

singleprocessor machines. On a singleprocessor machine, the kernel

will run faster if you say N here.
