I've just replied to [0/5] from the previous series, here:

[PATCH v5 0/5] Xen/ACPI: support sleep state entering on hardware reduced systems
In version 3.4 acpi_os_prepare_sleep() got introduced in parallel with
reduced hardware sleep support, and the two changes didn't get
synchronized: The new code doesn't call the hook function (if so
requested). Fix this, requiring a boolean parameter to be added to the
hook function to distinguish "extended" from "legacy" sleep.
This requires adjusting TXT, but the adjustments only go as far as
failing the extended mode call (since, looking at the TXT interface,
there doesn't even appear to be precautions to deal with that
alternative interface).
The hypervisor change underlying this is commit 62d1a69 ("ACPI: support
v5 (reduced HW) sleep interface") on the master branch of
git://xenbits.xen.org/xen.git.

[PATCH v5 0/5] Xen/ACPI: support sleep state entering on hardware reduced systems
In version 3.4 acpi_os_prepare_sleep() got introduced in parallel with reduced hardware sleep support, and the two changes didn't get synchronized: The new code doesn't call the hook function (if so requested). Fix this, requiring a boolean parameter to be added to the hook function to distinguish extended from legacy sleep. This requires adjusting TXT, but the adjustments only go as far as failing the extended mode call (since, looking at the TXT interface, there doesn't even appear to be precautions to deal with that alternative interface).
