linux-next: manual merge of the tip tree with the btrfs, zstd trees

[Stephen Rothwell]

Hi all,

Today's linux-next merge of the tip tree got a conflict in:

  lib/zstd/common/portability_macros.h

between commit:

  65d1f5507ed2 ("zstd: Import upstream v1.5.7")

from the btrfs, zstd trees and commit:

  1400c87e6cac ("zstd: Increase DYNAMIC_BMI2 GCC version cutoff from 4.8 to 11.0 to work around compiler segfault")

from the tip tree.

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.
