[Xen-devel] [PATCH] Allow to set >8 for NR_CPUS on x86_64 xenlinux
The patch allows one to configure NR_CPUS >8 (16 by default, same as the native) for x86_64 xenlinux. I tested 16-way xenolinux (using changeset 7892) on a 16-way SMP machine with >8GB memory. It worked fine as long as I did sanity tests like kernel build (make -j64).

This is the first time that 16-way PAE xenlinux booted on that machine! Even a week ago, it was failing to boot.
