This breaks platforms like sparc64 because PTRS_PER_PMD is not
a compile time constant. It is actually dependant upon whether
the current thread is using a 32-bit or 64-bit address space.
Not sure I follow.... Oh, if it is just a matter of that
breaking the conditional compilation then OK, hmm.
These functions will simply never be called if the relevant
PTRS_PER_XXX is 1. Actually it is dependant on p?d_none
always being false.
So you shouldn't even need that runtime check there I think.
The #if was just a small space saving, but you could simply
remove that and be done with it I think. Or have I missed
something?
