Cover letter [PATCH 0/4] Hibernate: Handle ACPI NVS memory as required by the spec

Hi,

I have recently tried to rebase the Zhang Rui's patches making the Linux hibernation code handle the ACPI NVS memory as required by the spec, but I found that they didn't work on x86_64 boxes where the NVS region was located behind the last usable PFN. Also, I decided to put the memory management part into the hibernation core rather than into drivers/acpi/sleep/main.c .

As a result, I have obtained the following patch series. Please review and if it looks good, please queue in the 'suspend' branch as .29 material.

Thanks,
Rafael
