[PATCH] x86: Don't use nested idle loops
Currently the idle loop has two nested loops -- one high level
in cpu_idle and in some low level idle functions another one.
Looping in the low level idle functions breaks the idle notifiers
because interrupts waking up sleep states need to execute
exit_idle() which is only in cpu_idle().
So don't do that, only loop in cpu_idle(). This only removes
code.
In some cases e.g. poll_idle the idle loop is a little longer
now because cpu_idle checks more things. I hope that isn't a problem
ACPI idle doesn't change behaviour because it never looped anyways.
