[Xen-devel] [PATCH 0/2] ACPI: fixes to acpi_os_map_memory()

["Jan Beulich" <JBeulich@xxxxxxxx>]

1: ACPI: fix acpi_os_map_memory()
2: ACPI: use ioremap() in acpi_os_map_memory()

While this could have been done in one step for unstable, backports to
older trees (where we don't have a proper ioremap()) will become better
aligned with the unstable commits this way - the first patch can be
backported, while the second would at most go into 4.3-testing.

This fixes booting on upcoming systems of a vendor who couldn't make
up their minds whether they would want to be named here (and hence
I'm keeping them anonymous), where various of the ACPI registers
traditionally located in I/O space show up in "System Memory" instead.
