Revert "ip6_vti: adjust vti mtu according to mtu of lower device"

2018-04-08T09:52:02+00:00

This reverts commit 2fe832c678189d6b19b5ff282e7e70df79c1406b which is
commit 53c81e95df1793933f87748d36070a721f6cb287 upstream.

Ben writes that there are a number of follow-on patches needed to fix
this up, but they get complex to backport, and some custom fixes are
needed, so let's just revert this and wait for a "real" set of patches
to resolve this to be submitted if it is really needed.

net: cavium: liquidio: fix up "Avoid dma_unmap_single on uninitialized ndata"

2018-04-08T09:52:02+00:00

This fixes up commit 1d1cb762524f05cfb37994e0d36b7b4b5e957134 which was
commit 8e6ce7ebeb34f0992f56de078c3744fb383657fa upstream.

Ben writes:
	This goto should not have been changed, as no DMA mapping has been
	attempted at this point in the function.

	This seems to have been fixed upstream by commit 6a885b60dad2 "liquidio:
	Introduce new octeon2/3 header".  I leave it to you to work out how it
	should be fixed in 4.4-stable.

Fix this up by hand, as the referenced patch isn't worthy of being
backported.

    commit 8aedbf580d21121d2a032e4c8ea12d8d2d85e275
    Author: Fabien Parent 
    Date:   Thu Feb 23 19:01:56 2017 +0100

	spi: davinci: Use SPI framework to handle DMA mapping

    which is not suitable for stable.

So I'm just fixing this up directly.

Revert "mtip32xx: use runtime tag to initialize command header"

2018-04-08T09:52:02+00:00

This reverts commit 9bf9e352ed51d4cdee107675609ba12b42d00c5b which was
commit a4e84aae8139aca9fbfbced1f45c51ca81b57488 upstream.

	MQ IO schedulers were introduced in 4.11, so this shouldn't be

	regression (fixed upstream).  Please revert this for 4.4 and
	4.9.

So let's revert it!

commit 7be4b5dc7ffa9499ac6ef33a5ffa9ff43f9b7057 upstream.

It requires a driver that was not merged until 4.16, so remove it from
this stable tree as it is pointless.

The dependancy tree is just too messy here, just drop it from this
kernel as it's not really needed here.

nospec: Kill array_index_nospec_mask_check()

2018-04-08T09:52:01+00:00

commit 1d91c1d2c80cb70e2e553845e278b87a960c04da upstream.

There are multiple problems with the dynamic sanity checking in
array_index_nospec_mask_check():

* It causes unnecessary overhead in the 32-bit case since integer sized
  @index values will no longer cause the check to be compiled away like
  in the 64-bit case.

* In the 32-bit case it may trigger with user controllable input when
  the expectation is that should only trigger during development of new
  kernel enabling.

* The macro reuses the input parameter in multiple locations which is
  broken if someone passes an expression like 'index++' to
  array_index_nospec().
