| |
The patch "make page-aligned data and bss less fragile" introduces __page_aligned_data and __page_aligned_bss to make sure that page aligned things remain so, even if there are non-page-sized page-aligned things.
This paragraph converts an instance of an explicit section attribute to __page_aligned_data. It's purely decorative.
(It should be noted that powerpc already defines __page_aligned to have the same meaning as __page_aligned_data in non-MODULE code. Also this particular case looks like it could be __page_aligned_bss rather than data, but I didn't want to change the meaning of the code.)
