But lets also fix another unmap/remap bug before the cleanups... This series doesn't depend on the previous mremap fixes.
special_mapping_fault() is absolutely broken. It seems it was always wrong, but this didn't matter until vdso/vvar started to use more than one page.
I am not sure about 1/3. As the changelog says the name is not very accurate, and I do not really like the vma->fault != NULL check. But I hope this can work, and we can change this helper later if needed.
Please review.
Oleg.
