This error also popped up when I fiddled with omap2plus_defconfig on top
of next-20141117. Note that I ended up with a .config which has
CONFIG_ARCH_MULTI_V7 set. The error appears to be triggered by the
Kconfig entry for ARCH_EXYNOS (in arch/arm/mach-exynos/Kconfig). It
contains
select PM_GENERIC_DOMAINS if PM_RUNTIME
(Perhaps the :272: line needs rephrasing in the error Stephen quoted. It
confused me quite a bit.)
Naively dropping that select statement from ARCH_EXYNOS triggered yet
another error:
kernel/power/Kconfig:145:error: recursive dependency detected!
kernel/power/Kconfig:145: symbol PM depends on PM_RUNTIME
kernel/power/Kconfig:132: symbol PM_RUNTIME is selected by
PM_GENERIC_DOMAINS
kernel/power/Kconfig:272: symbol PM_GENERIC_DOMAINS is selected by PM
After that I admitted defeat.
