There are hardware limitations on the number of available MSIs,
which firmware expresses using a property named "ibm,pe-total-#msi".
This property tells us how many MSIs are available for devices below
the point in the PCI tree where we find the property.
For old firmwares which don't have the pro

If a driver asks for more MSIs than the devices "req#msi(-x)" property,
we currently return -ENOSPC. This doesn't give the driver any chance to
make a new request with a number that might work.
So if "req#msi(-x)" is less than the request, return its value. To be
100% safe, make sure we return an

While testing partition migration with heavy CPU load using
shared processors, it was observed that sometimes the migration
would never complete and would appear to hang. Currently, the
migration code assumes that if H_SUCCESS is returned from the H_JOIN

Impact: fix potential (non-x86) SMP boot failure with some gcc versions
The deprecated cpu_*_map are currently #defined to the new cpu_*_mask,
except without the const. Some versions of gcc seem to dislike this,
and I suspect this will break boot for some archs with the "wrong" gcc
version.
