the entire configuration of the thermal zone.

Address an unlikely null pointer dereference.
Fixes commit 7b5df13bc4b3 ("mm: swap: free up swap on mm reap").
The expected usage of free_swap_slot is that the caller has already
checked that the swap_entry_t is valid.

The avc allocations are marked with GFP_NOWAIT and thus
considered to be non-fatal allocations. This also makes
these allocations easy to fail thus filling the log buffer
with page allocation failure messages. There are no known
cases of these messages being of any importance for
debugging. Disable them.

When a buffer is added to the LRU list, a reference is taken which is
not dropped until the buffer is evicted from the LRU list. This is the
correct behavior, however this LRU reference will prevent the buffer
from being dropped. This means that the buffer can't actually be dropped
until it is selected for eviction. There's no bound on the time spent
on the LRU list, which means that the buffer may be undroppable for
very long periods of time. Given that migration involves dropping
buffers, the associated page is now unmigratible for long periods of
time as well. CMA relies on being able to migrate a specific range
of pages, so these these types of failures make CMA significantly
less reliable, especially under high filesystem usage.
Rather than waiting for the LRU algorithm to eventually kick out
the buffer, explicitly remove the buffer from the LRU list when trying
to drop it. There is still the possibility that the buffer
could be added back on the list, but that indicates the buffer is
still in use and would probably have other 'in use' indicates to
prevent dropping.

Even though best_energy_cpu is idle and which would consume
same amount of energy as prev cpu, due to 6% check with prev cpu,
we end up choosing prev cpu over best_energy_cpu for the tasks.
This leads to increase in runnables. Choose best_energy_cpu when
it is idle and shallowest c-state over prev cpu in such scenarios
to avoid runnables.

The current mux_get_parent logic attempts to find the parent index by
passing the HW parent to qcom_find_src_index, which compares against the
logical value (parent_map::src) instead of the raw HW value
(parent_map::cfg). This can lead to improperly parented muxes or orphans
since there is no guarantee that the logical values match the HW values.
Add a new helper function (qcom_find_cfg_index), which returns the index
associated with the HW parent value (parent_map::cfg). Call this
function in mux_get_parent instead of qcom_find_src_index to fix the
improper mux parents.
