Backporting commit 120a264f9c27 ("drm/exynos: gem: Drop NONCONTIG flag
for buffers
allocated without IOMMU") depends on commit

30b0da8d556e ("drm: extra printk() wrapper macros")

which was merged into linux-4.9.

Backporting commit 89c5a2d34bda ("efi/esrt: Use memunmap() instead of kfree() to
free the remapping") depends on commit

f58a37b2e01f ("efi/esrt: Use memremap not ioremap to access ESRT table
in memory")

which was also merged into linux-4.9. To backport those to into
kernels earlier than v4.3,
you'd also need commit 92281dee825f ("arch: introduce memremap()"),
which is probably
too invasive to backport.
