An upcoming patch makes ARCH_SUPPORTS_KEXEC_HANDOVER depend on
CRASH_DUMP on powerpc:
config ARCH_SUPPORTS_KEXEC_HANDOVER
def_bool y
depends on PPC64
depends on !CRASH_DUMP
That triggers a recursive dependency error:
error: recursive dependency detected!
symbol KEXEC_HANDOVER depends on ARCH_SUPPORTS_KEXEC_HANDOVER
symbol ARCH_SUPPORTS_KEXEC_HANDOVER depends on CRASH_DUMP
symbol CRASH_DUMP depends on KEXEC_CORE
symbol KEXEC_CORE is selected by KEXEC_FILE
symbol KEXEC_FILE is selected by KEXEC_HANDOVER
KEXEC_HANDOVER and KEXEC_CORE end up depending on each other when
ARCH_SUPPORTS_KEXEC_HANDOVER depends on CRASH_DUMP. This creates a
recursive Kconfig dependency.
Change KEXEC_FILE from select to depends on to break this cycle.
This means KEXEC_FILE must be enabled explicitly instead of being
enabled automatically by KEXEC_HANDOVER.
Keep this change until the powerpc-specific KHO and CRASH_DUMP
dependency is resolved.
