[PATCH 0/3] Limit upper virtual memory range to ofmem_arch_get_virt_top()

[Mark Cave-Ayland]

Some further work on trying to boot Solaris under qemu-system-sparc64 shows that
allowing the full virtual memory range in the available property causes the memory
list calculations to overflow.

The first couple of patches fix up SPARC32/SPARC64 to set the appropriate upper
virtual memory limits (PPC is already correct), whilst the last patch enables the
upper limit in the OFMEM virtual memory allocator.

With this patchset applied, 64-bit Solaris 9 gets beyond the "VAC too big!" panic upon
boot and fails further down the line trying to setup the kernel memory regions.
