The previous version of this patch didn't get any response, so on the
"no news is good news" theory ... Any comments before I send this off to
Marcelo?

This adds a new x86-only sysctl, /proc/sys/kernel/idle_poll, which does
basically the same thing as the "idle=poll" boot parameter (except that
it can be turned on and off).

This patch does not affect the ability of the APM and/or ACPI subsystems
to override the default idle function.  It adds one symbol,
pm_idle_poll, to the global namespace.

This patch applies cleanly to 2.4.23, 2.4.24, and 2.4.25-pre4.
