It occurred to me that we don't require holding a lock when patching
text. Many use cases do hold text_mutex, but it's not required, so it's
possible for this warning to show false positives.
If we do want text_mutex be held, then lockdep_assert_held(_mutex)
ought to be added too.

pci-mvebu.c uses irq_domain_add_linear() and related interfaces but relies
on but doesn't include it directly; it relies on the

Include directly to remove this implicit dependency.

The git history for this driver seems to be completely

or systems which would use this chip. Google search
shows pictures of towel warmers and no networking products.

Woo-hoo!
That was quick, for once.

Oh.
Well, close enough, and those fixes are presumably pending too.
