Hmmm..I'm looking at the patch on my local machine and it doesn't have
any whitespace damage. If there is whitespace damage it was caused by
something else (like hg email is doing something).

I've attached the orginal patch to this email.

[kvm-ppc-devel] [PATCH 3 of 3] Fix memory defined in device tree by

[Jerone Young]

1 file changed, 4 insertions(+)
qemu/hw/ppc440_bamboo.c |    4 ++++


This fixes a issue where the amount of memory is not properly being defined in the device tree. It currently is hardcoded for 144MB. The result is that if you specify a memory size below the hardcoded size, the guest crashes. This patch now dynamically changes the device tree to the memory value specified.

This fixes a issue where the amount of memory is not properly being defined in the device tree. It currently is hardcoded for 144MB. The result is that if you specify a memory size below the hardcoded size, the guest crashes. This patch now dynamically changes the device tree to the memory value specified.
