Hello, all.
This patchset deals with some problematic sites that iterate pfn range.
There is a system that node's pfn are overlapped like as following.

alloc_gigantic_page() uses alloc_contig_range() and this
requires that requested range is in a single zone. To satisfy
that requirement, add this check to pfn_range_valid_gigantic().

The aio changes have either been reviewed negatively or not at all. That
tree should be dropped.

Just curious: why are you using the old MD multipath driver that's
been depcrecated in favor of DM multipath a long time ago?

Please describe what the problem is. There is no way that anyone can figure
out why that patch is required, what it fixes and how the fix is done
