With Intel Turbo Boost Max Technology 3.0 (ITMT), single-threaded performance is
optimized by identifying processor's fastest core and running critical workloads
on it.

On platforms supporting Intel Turbo Boost Max Technology 3.0, the maximum

We appreciate feedback about this patch series from the
community. Historically, neither the performance nor latency of the swap
path mattered. The underlying I/O was slow enough to hide any latency
coming from software and the low IOPS kept the overall CPU impact low.

The patch is to improve the scalability of the swap out/in via using
fine grained locks for the swap cache. In current kernel, one address
space will be used for each swap device. And in the common
configuration, the number of the swap device is very small (one is
typical).
We add per cpu caches for swap slots that can be allocated and freed
quickly without the need to touch the swap info lock.
Two separate caches are maintained for swap slots allocated and
swap slots returned. This is to allow the swap slots to be returned
to the global pool in a batch so they will

swap_info_get() is used not only in swap free code path but also in

The current "rodata=off" parameter disables read-only kernel mappings
under CONFIG_DEBUG_RODATA:

Other modules may be using this in the future, so export it.

This patch adds logic to allows a process to migrate other tasks
between cgroups if they have CAP_SYS_RESOURCE.
In Android (where this feature originated), the ActivityManager tracks
