fsl_ssi uses different stream names ("AC97 Playback" / "AC97 Capture")
in AC'97 mode so in this case fsl-asoc-card route map should
also be using them.

When retpolines are enabled they have high overhead in the inner loop
inside kvm_handle_hva_range() that iterates over the provided memory area.
Let's mark this function and its TDP MMU equivalent __always_inline so
compiler will be able to chang

While the new benchmark was used to measure the performance of these
changes, it is otherwise independent of them, that's why it was submitted
as a separate series.

It looks like rtlwifi/rtl8192cu AP mode is broken when a STA is using PS,
since the driver does not update its beacon to account for TIM changes,
so a station that is sleeping will never learn that it has packets
buffered at the AP.
Looking at the code, the rtl8192cu driver implements

Memslot ID to the corresponding memslot mappings are currently kept as

The size of this array depends on the maximum allowed memslot count

Introduce a memslots gfn upper bound operation and use it to optimize
