coprocessor_flush is not a part of fast exception handlers, but it uses

In host control mode, reads are the major source of activation trials.
Keep track of those reads counters, for both active as well inactive
regions.
We reset the read counter upon write - we are only interested in "clean"
reads. less intuitive however, is that we also reset it upon region's

In order not to hang on to “cold” regions, we shall inactivate a
region that has no READ access for a predefined amount of time -
READ_TO_MS. For that purpose we shall monitor the active regions list,

In order to be able to add the second VPU (for HECV decoding) it will be
more handy if the both VPU drivers instance don't have to share the
control block registers. This lead to implement it as an i
IMX8MQ SoC got a dedicated hardware block to reset the video processor
units (G1 and G2).

Rather use a reset like feature inside the driver use the reset
controller API to get the same result.

Trying to set or clear PG_lru on tail pages has been considered buggy.
Enforce this rule by changing the policy for PG_lru from PF_HEAD to

be "corrected" by compound_page(). Such "correction" isn't helpful --

Sparse can do constant folding of __builtin_bswap*() since 2017.
Also, a much recent version of Sparse is needed anyway, see
commit 6ec4476ac825 ("Raise gcc version requirement to 4.9").
So, remove the comment about sparse not being yet able to constant
fold __builtin_bswap*() and remove the corre

There are two ref count variables controlling the free()ing of a socket:
- struct sock::sk_refcnt - which is changed by sock_hold()/sock_put()
- struct sock::sk_wmem_alloc - which accounts the memory allocated by

In case there are still TX skbs on the fly and the socke
