seabios (master branch) just got 64bit pci support.  When running out of
address space in the pci memory window below 4G (0xe0000000+) seabios
will map 64bit pci bars above 4G to make room below 4G.

This patch series carries two little patches for qemu to adapt it to the
seabios changes.  First patch creates a memory window for the 64bit pci
bars.  Second patch adds a 64bit option to the ivshmem driver, which
allows to use huge shared memory chunks.

please review & apply,
