[PATCH] paravirt: remove NO_IDLE_HZ on x86
Browse files Browse the repository at this point in the history
Temove the mistaken turning on of NO_IDLE_HZ on x86+PARAVIRT kernels.

It's an obsolete, limited form of dynticks.

Switches the regular HZ timer off when the system is going idle.
This helps a hypervisor detect that the Linux system is idle,
reducing the overhead of idle systems.
