. Since most code that has page-aligned data
structures is architecture-specific, there's a good chance that any new
code that would break will be at least looked at by you (and given how few
places it is used currently, this seems pretty unlikely to actually come
up).
-Tim Abbott
There is already an architecture-independent __page_aligned_data macro
for this purpose, so removing the powerpc-specific macro should be
harmless.
