• typo

Seems fine to me. I'd wait to see if @vmaffione has any comments.

• mention that iscsi sysctls are now in milliseconds instead of seconds

Again, I do not think it is correct.
I looked at the patch more closely. I believe all you need is a hook into vm_phys_fictitious_reg_range()/unreg_range() that would register and unregister lkpi_phy_segs entries as needed. Then the segments would be used by lkpi_vm_page_to_page() of course (the main reason why it is needed). I think it is fine to add lkpi hooks pointers to vm_phys.c and provide some void *priv for phys segments.

This seems reasonable. But bnxt_ktls_pre_xmit() seems to use the same pattern that you're fixing here. Does it also need the same fix?

fixup against Alder Lake and Raptor Lake PCHs

Update to 4.4.0 and fix the UPDATING entry

Thanks for doing this. These files confused me and they should be removed. The only thing I would add is that perhaps you should leave a pointer to the continuation as a form of advertisement and breadcrumb
