      mm: remove obsolete alloc_remap() · 79375ea3
      由 Arnd Bergmann 提交于 
      Tile was the only remaining architecture to implement alloc_remap(),
and since that is being removed, there is no point in keeping this
function.

Removing all callers simplifies the mem_map handling.

      mm: remove blackfin MPU support · 1a842913
      由 Arnd Bergmann 提交于 
      The CONFIG_MPU option was only defined on blackfin, and that architecture
is now being removed, so the respective code can be simplified.

A lot of other microcontrollers have an MPU, but I suspect that if we
want to bring that support back, we'd do it differently anyway.

      procfs: remove CONFIG_HARDWALL dependency · e05a959f
      由 Arnd Bergmann 提交于 
      Hardwall is a tile specific feature, and with the removal of the
tile architecture, this has become dead code, so let's remove it.

      CRIS: Drop support for the CRIS port · c690eddc
      由 Jesper Nilsson 提交于 
      The port was added back in 2000 so it's no longer even a good source
of inspiration for newer ports (if it ever was)

The last SoC (ARTPEC-3) with a CRIS main CPU was launched in 2008.

Coupled with time and working developer board hardware being
in low supply, it's time to drop the port from Linux.

So long and thanks for all the fish!

      arch: remove tile port · bb9d8126
      由 Arnd Bergmann 提交于 
      The Tile architecture port was added by Chris Metcalf in 2010, and
maintained until early 2018 when he orphaned it due to his departure
from Mellanox, and nobody else stepped up to maintain it. The product
line is still around in the form of the BlueField SoC, but no longer
uses the Tile architecture.

There are also still products for sale with Tile-GX SoCs, notably the
Mikrotik CCR router family. The products all use old (linux-3.3) kernels
with lots of patches and won't be upgraded by their manufacturers. There
have been efforts to port both OpenWRT and Debian to these, but both
projects have stalled and are very unlikely to be continued in the future.

Given that we are reasonably sure that nobody is still using the port
with an upstream kernel any more, it seems better to remove it now while
the port is in a good shape than to let it bitrot for a few years first.

      arch: remove blackfin port · 4ba66a97
      由 Arnd Bergmann 提交于 
      The Analog Devices Blackfin port was added in 2007 and was rather
active for a while, but all work on it has come to a standstill
over time, as Analog have changed their product line-up.

Aaron Wu confirmed that the architecture port is no longer relevant,
and multiple people suggested removing blackfin independently because
of some of its oddities like a non-working SMP port, and the amount of
duplication between the chip variants, which cause extra work when
doing cross-architecture changes.

Remove metag architecture

These patches remove the metag architecture and tightly dependent
drivers from the kernel. With the 4.16 kernel the ancient gcc 4.2.4
based metag toolchain we have been using is hitting compiler bugs, so
now seems a good time to drop it altogether.
