linux-next: manual merge of the gpio-brgl tree with the arm64 tree

[Stephen Rothwell]

Hi all,

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

  arch/arm64/Kconfig

between commit:

  3b619e22c460 ("arm64: implement dynamic shadow call stack for Clang")

from the arm64 tree and commit:

  f5a681d23888 ("arm64: Remove CONFIG_ARCH_NR_GPIO")

from the gpio-brgl 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.
