Blue hasn't been active in the QEMU project for a long time. Drop his
last MAINTAINERS entries.
As per Paolo's recommendation, downgrade status of "BSD user" from
Maintained to Orphan since the FreeBSD guys effectively forked it, and
"SPARC target" from Maintained to Odd Fixes, since we still have the
overall TCG maintainer looking after it.
I'm leaving Checkpatch's status at Odd Fixes. Calling it Maintained
wouldn't be wrong, but I'm not comfortable upgrading it while nobody
is willing to have his name nailed to the thing.

Commit 0544edd88a "vl: smp_parse: cleanups" regressed any -smp
config that left either cores or threads unspecified, and specified
a topology supporting more cpus than the given online cpus. The
correct way to calculate the missing parameter would be to use
maxcpus, but it's too late to change that now. Restore the old
way, which is to calculate it with the online cpus (as is still
done), but then, if the result is zero, just set it to one.

The isa_bus_irqs function initializes ISA bus IRQ array pointer with specified
value.
Previously the ICH9 LPC bridge model did not have its own IRQs but
only IRQ pointer cache. And same GSI were used for ISA bus and other sources
behind the bridge (PCI, SCI). Hence, the pc_q35_init was only possible place to
setup both ISA bus IRQs and the bridge IRQ cache.
As a result, the call of isa_bus_irqs was made from pc_q35_init.
Now the ICH9 LPC bridge has its own output IRQs which are connected to GSI. The
output IRQs are already used to route IRQs from PCI and SCI.
The patch makes the ICH9 LPC bridge output IRQs to used for ISA bus too.
