fb8e837539 x86: sparsemem: reduce i386 PAE section size
A 1G section size makes memory hotplug too coarse in a virtual
environment.  Retuce it by a factor of 2 to 512M.  I would have liked
to make it smaller, but it runs out of reserved flags in the page flags.

8434e73d9e x86: increase max physical memory size of 64-bit
Increase the maximum physical address size of x86_64 system
to 44-bits. This is in preparation for future chips that
support larger physical memory sizes.
