Some big.LITTLE systems have I-Cache line size mismatch between
LITTLE and big cores. This patch adds a workaround for proper I-Cache
support on such systems. Without it, some class of the userspace code
(typically self-modifying) might suffer from random SIGILL failures.

Similar workaround already exists for ARM64 architecture. I has been
added by commit 116c81f4 ("arm64: Work around systems with mismatched
cache line sizes").

Compared to kernel 5.0, patches merged for 5.1 added support for A38x'
PHY guarded by a config option which was not enabled by default. As a
result, there was no eth1 and eth2 on a Solid Run Clearfog Base.

Ensure that A38x PHY is enabled on mvebu.

After discussing with the subarch maintainers and Hilscher,
we concluded that the netx subarchitecture (Netx 100/500)
is no longer maintained or tested, and noone will miss it
if we delete it. So delete it.

There is a newer Netx 4000 architecture which we may see
included at some point, but this will be supported using
the standard multiplatform and devicetree mechanisms and is
easier to develop from scratch.

The module support for the thermal subsystem makes little sense:
 - some subsystems relying on it are not modules, thus forcing the
   framework to be compiled in
 - it is compiled in for almost every configs, the remaining ones
   are a few platforms where I don't see why we can not switch the thermal
   to 'y'. The drivers can stay in tristate.
 - platforms need the thermal to be ready as soon as possible at boot time
   in order to mitigate

Usually the subsystems framework are compiled-in and the plugs are as
module.

Remove the module option. The removal of the module related dead code will
come after this patch gets in or is acked.

Currently support for 64-bit sector_t and blkcnt_t is optional on 32-bit
architectures.  These types are required to support block device and/or
file sizes larger than 2 TiB, and have generally defaulted to on for
a long time.  Enabling the option only increases the i386 tinyconfig
size by 145 bytes, and many data structures already always use
64-bit values for their in-core and on-disk data structures anyway,
so there should not be a large change in dynamic memory usage either.

Dropping this option removes a somewhat weird non-default config that
has cause various bugs or compiler warnings when actually used.
