Convert acpi_wakeup_address from a raw variable into a function so that x86 can wrap its dereference of the real mode boot header in a function instead of broadcasting it to the world via a #define. This sets the stage for a future patch to move the definition of acpi_wakeup_address() out of asm/acpi.h and thus break acpi.h's dependency on asm/realmode.h.
No functional change intended.

acpi_set_waking_vector(acpi_wakeup_address());You might want to store result in a variable... especially since you are turning inline function into real one in a next patch.
And maybe function should be called get_acip_wakeup_address or something? This way it is easy to mistake actual wakeup address from function that gets it...
Agreed on both counts.
Ingo,
Would you prefer a v2 of the entire series (with Acks and removal of Fixes), or a v2 that includes only the last two patches?
