Details for build failures below. Several improvements since last week,
but it looks like the alpha related pci_iounmap patches still need some

and many similar errors. Seen in xtensa:allmodconfig.

Background:
	xtensa:allmodconfig enables KASAN which in turn increases stack size
	requirements significantly.
