[PATCH] x86-64: do not use virt_to_page on kernel data address
o virt_to_page() call should be used on kernel linear addresses and not
on kernel text and data addresses. Swsusp code uses it on kernel data
(statically allocated swsusp_header).
o Allocate swsusp_header dynamically so that virt_to_page() can be used
safely.
o I am changing this because in next few patches, __pa() on x86_64 will
no longer support kernel text and data addresses and hibernation breaks.
