Yes, all sorts of randconfig builds hit different parts here > What's the Kconfig option enabling these errors? >>From what I can tell, this is simply a result of enabling CONFIG_SPARSE_IRQ, which results in linux/irq.h no longer implicitly including mach/hardware.h through mach/irqs.h. You should be able to see these errors by just enabling the respective drivers. The errors manifest as a long list of undefined symbols like /git/arm-soc/arch/arm/mach-omap1/io.c:33:28: error: 'OMAP1_IO_OFFSET' undeclared here (not in a function) /git/arm-soc/arch/arm/mach-omap1/io.c:43:14: error: 'OMAP7XX_DSP_BASE' undeclared here (not in a function) /git/arm-soc/arch/arm/mach-omap1/serial.c:114:33: note: each undeclared identifier is reported only once for each function it appears in /git/arm-soc/arch/arm/mach-omap1/pm.c:217:23: error: 'ULPD_SOFT_DISABLE_REQ_REG' undeclared (first use in this function) /git/arm-soc/drivers/video/fbdev/omap/sossi.c:608:17: error: 'MOD_CONF_CTRL_1' undeclared (first use in this function) Then again, it is possible that I only see the errors because of an interaction with another patch from my randconfig fixes series.
