Subject: linux-next: manual merge of the mm tree with the crypto tree
Hi all,
Today's linux-next merge of the mm tree got a conflict in:
crypto/Kconfig
between commit:
28a936ef44e1 ("crypto: Kconfig - move x86 entries to a submenu")
and several others :-(
from the crypto tree and commit:
4a86344bcbc9 ("crypto: kmsan: disable accelerated configs under KMSAN")
from the mm tree.
I fixed it up (I used the former version and then added the following
merge fix patch) and can carry the fix as necessary. This is now fixed
as far as linux-next is concerned, but any non trivial conflicts should
be mentioned to your upstream maintainer when your tree is submitted for
merging. You may also want to consider cooperating with the maintainer
of the conflicting tree to minimise any particularly complex conflicts.
