I fixed it up (see below) 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. --=20 Cheers, Stephen Rothwell diff --cc Documentation/admin-guide/kernel-parameters.txt index 5a67e409d370,4167bbea51e1..000000000000 --- a/Documentation/admin-guide/kernel-parameters.txt +++ b/Documentation/admin-guide/kernel-parameters.txt @@@ -2761,10 -2687,10 +2761,14 @@@ nosmt [KNL,S390] Disable symmetric multithreading (SMT).
