Re: [PATCH v3 0/3] arm64: use hierarchical XN permissions for all page tables

This series tweaks the page table population code to set the UXNTable and
PXNTable bits as appropriate when page tables are being allocated and linked
into a page table hierarchy. On table entries that cover the linear region,
both PXN and UXN are set; for other page tables, either the UXN or PXN
attribute is set on all table entries, depending on whether the hierarchy in
question is intended to be used by the kernel or by user space.

Applied to arm64 (for-next/xntable), thanks!
