Thanks, I'll take it for inclusion into the build testing framework.
The appended patch fixes the problem for me.
Thanks,

Subject: ACPI / PM: Fix build for unusual combination of Kconfig options
CONFIG_PM_SLEEP may be set even if CONFIG_ACPI_SLEEP is unset,
although that is unusual. For this reason, make the headers of
functions built for both CONFIG_ACPI and CONFIG_PM_SLEEP set
simultaneously depend on that combination of Kconfig options
instead of CONFIG_ACPI_SLEEP.
This fixes a build problem reported by Randy Dunlap.
