Hi All, This series is on top of the git branch at git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \ acpica-osl and it basically makes the deferred unmapping of ACPI memory introduced by the first commit in that branch be the only option. Arguably, it could be done in a single patch, but I prefer to do that in smaller steps in case something breaks, to make it easier to identify the point of breakage. Patch [1/3] causes acpi_os_unmap_generic_address() to use the deferred unmapping, patch [2/3] makes acpi_os_unmap_iomem() use it too and patch [3/3] is a cleanup of top of the latter. Thanks, Rafael
