Hi, This series revisits a once-trendy topic: TLB invalidation support for multi-gt. It's a theme that's been passed around and reshaped by several of us. I've filtered out most of the original changes from this series, initially sent by Mauro [1]. His ideas were inspired by some changes from Chris, who in turn was inspired by a change from me[2], all of which stemmed from offline talks by Chris (it's like a game of inspiration tag!). What I've done is simply rebase and refactor the patches, focusing solely on the changes needed for multi-gt TLB invalidation in MMIO memory. The result is a leaner, more targeted proposal. Other patches from the original series might follow.
