Should be a real function
Yes, except it's not trivially done because if __cli was an inline
function, you need to have everything that is used in the declaration
defined when the function is declared as opposed to when the #define
gets used. I'll give it another try, but it very quickly becomes
#include hell.
Anybody want to comment on the performance impact of making
local_irq_* non-inline functions?
I wasn't concerned with inline vs non-inline - that's your choice.
Just the inherent foulness of multi-line macros ;-)
