Details for build failures below. Several improvements since last week,
but it looks like the alpha related pci_iounmap patches still need some
tweaking (see error log at the very end).

drivers/video/fbdev/omap2/omapfb/dss/dsi.c:1623:1: error: the frame size of 1104 bytes is larger than 1024 bytes

and many similar errors. Seen in xtensa:allmodconfig.

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