This diff block is wrong.

The acpi/platform/aclinux.h is a "platform specific ACPICA environment header".
The linux/acpi.h is a "Top level header of Linux ACPI".
The asm/acpi.h is a combination of " architecture specific ACPICA environment header" and "architecture specific Linux ACPI header".

The relationship between Linux ACPI and ACPICA is:
Linux ACPI is using ACPICA.
So linux ACPI header should __INCLUDE__ ACPICA header, which means linux/acpi.h should include acpi/platform/aclinux.h.
You patch thus is wrong.

In fact, acpi/platform/aclinux.h is included by acpi/acpi.h and acpi/acpi.h is included by linux/acpi.h.

For asm/acpi.h, there are really things messed up in it.
I have a series to split its role so that wrong "architecture specific Linux ACPI header" can be sorted out from acpi/platform/aclinux.h.
Please refer to:
https://lkml.org/lkml/2014/4/8/57

The correct way to fix the issue you are trying to fix is this patch:
https://lkml.org/lkml/2014/4/8/60

So please drop this diff block and just wait for the above mentioned series to be merged.

Thanks and best regards
