Actually, what we also want is to do this when ACPI S5 is simply not supported on non-legacy platforms. Since some future Intel platforms are HW-full mode where the DSDT fails to supply an _S5 object(without SLP_TYP), we should let such kind of platform to leverage efi runtime service to poweroff. This patch uses efi power off as first choice when S5 is unavailable, even if there is a customized poweroff(driver provided, eg). Meanwhile, the legacy platforms will not be affected because there is no path for them to overwrite the pm_power_off to efi power off.

However Rafael J. Wysocki pointed out that the exported function acpi_dev_present() is easily confused with the non-exported acpi_device_is_present(). Additionally in ACPI parlance the term "present" usually refers to the "device is present" bit returned by the _STA control method, yet acpi_dev_present() merely checks presence in the namespace. It does not invoke _STA at all, let alone check the "device is present" bit. As suggested by Rafael, rename the function to acpi_dev_found() and adjust all existing call sites.

This patch fixes the issues by reverting the wrong support and implementing the default behavior of _OSI("Darwin")/_OSI("WinXXX") on Apple hardware via DMI matching.

This patch collects all _OSI handling code into one single file. So that we only have the following functions to be used externally: early_acpi_osi_init(): Used by DMI detections; acpi_osi_init(): Used to initialize OSI command line settings and install Linux specific _OSI handler; acpi_osi_setup(): The API that should be used by the external quirks. acpi_osi_is_win8(): The API is used by the external drivers to determine if BIOS supports Win8. CONFIG_DMI is not useful as stub dmi_check_system() can make everything stub because of strip. No functional changes.

This solution doesn't cover function types. Note that the linuxize result of this commit is very giant and should have many conflicts against the current Linux upstream. Thus it is required to modify the linuxize result of this commit and the commits around it manually in order to have them merged to the Linux upstream. Since this is very costy, we should do this only once, and if we can't ensure to do this only once, we need to revert the Linux code to the wrong indentation result before merging the linuxize result of this commit.
