This option tells the compiler NOT to build the code under
|

arch/powerpc with the -Werror flag (which means warnings
|
|
are treated as errors).
|

Only enable this if you are hitting a build failure in the

arch/powerpc code caused by a warning, and you don't feel

inclined to fix it.

This option allows you to set the stack depth that the kernel

prints in stack traces. This can be useful if your display is

too small and stack traces cause important information to

scroll off the screen.

Adds code to keep track of the number of hypervisor calls made and
|
|
the amount of time spent in hypervisor calls. Wall time spent in
|
|
each call is always calculated, and if available CPU cycles spent
|
|
are also calculated. A directory named hcall_inst is added at the
|
|
root of the debugfs filesystem. Within the hcall_inst directory
|
|
are files that contain CPU specific call statistics.

This option will add a small amount of overhead to all hypervisor

calls.
