[dpdk-stable] [PATCH 18.11 0/7] Backport GPA logging and performance

[Adrian Moreno <amorenoz@redhat.com>]

Backport the entire series [0] 'vhost: I-cache pressure optimizations'
because it is motivated by a performance degradation from v17.11.

Also pick [1] to allow for a clean backport of the GPA logging support.

The result is an almost clean backport. Only the lack of [2] generates
conflicts. But that is part of a feature [3] that, IMHO, does not meet the
requirements to be backported to the stable branch.
