Hi all,
Today's linux-next merge of the iommu tree got a conflict in:
arch/Kconfig
between commits:
0eb5085c3874 ("arch: remove ARCH_TASK_STRUCT_ON_STACK")
3888750e21cc ("arch: remove ARCH_TASK_STRUCT_ALLOCATOR")
from the mm-nonmm-stable tree and commit:
8f23f5dba6b4 ("iommu: Change kconfig around IOMMU_SVA")
from the iommu 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.

An architecture should select this to provide hardened usercopy
knowledge about what region of the thread_struct should be
