[PATCH 0/2] Fix swap and page migration for LPAE

Hello,

These two patches fix swapping and page migration for LPAE-enabled
kernels. Without these changes, we corrupt the offset stored in the file
pte when updating the page tables and may truncate the pfn when storing
it into a swp_entry_t.

I'll CC stable on the final patches.

All feedback welcome,

Will
