From: Alexander Gordeev
Commit 1a42010cdc26 ("s390/mm: convert to the generic get_user_pages_fast

dynamic page table folding.
The question "What would it require for the generic code to work for s390"

From: Alexander Gordeev
Since pXd_addr_end() macros take pXd page-table entry as a
parameter it makes sense to check the entry type on compile.
Even though most archs do not make use of page-table entries
in pXd_addr_end() calls, checking the type in traversal code
paths could help to avoid subtl

Hi,
we have some more improvements for PCIe aardvark controller (Armada 3720
SOC - EspressoBIN and Turris MOX).
The main improvement is that with these patches the driver can be compiled
as a module, and can be reloaded at runtime.
