| |
These macros are often used by drivers and we have already a lot of duplication as ICPU() macro across the drivers.
Provide a generic x86 macro for users.
Note, as Ingo Molnar pointed out this has a hidden issue when a driver needs to preserve const qualifier. Though, it would be addressed separately at some point.
