Sorry I didn't notice earlier, but that BUG_ON triggers for me on the
simulator. AFAICS the mask for itv is set in cpu_init(), which comes
after sal_init(). Consequently on the simulator the itv still has its
start value of zero. I've probably missed something, but I wonder why
at this stage of the boot you even need to save and restore the itv?

If SAL_CACHE_FLUSH drops interrupts, complain about it and fall back to
using PAL_CACHE_FLUSH instead.
This is to work around a defect in HP rx5670 firmware: when an interrupt
occurs during SAL_CACHE_FLUSH, SAL drops the interrupt but leaves it marked
"in-service", which leaves the interrupt (and others of equal or lower
priority) masked.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
