Summary:
GENERIC_CLOCKEVENTS is not enabled. (ia64)
COMPILE_TEST=y
#
# Clock Source drivers
#
CONFIG_TIMER_OF=y
CONFIG_CLKSRC_MMIO=y
# CONFIG_CLKSRC_PISTACHIO is not set
CONFIG_ARMV7M_SYSTICK=y
# CONFIG_ATMEL_PIT is not set
CONFIG_CLKSRC_ST_LPC=y
Both ARMV7M_SYSTICK and CLKSRC_ST_LPC select TIMER_OF (if OF, which is enabled)
and select CLKSRC_MMIO. TIMER_OF depends on GENERIC_CLOCKEVENTS (=n), but
'select' does not care about that "depends on".
This build error only happens because COMPILE_TEST=y.
Any driver that does 'select TIMER_OF' should also depend on GENERIC_CLOCKEVENTS.
The problem is that some drivers do 'select TIMER_OF if OF', so if OF is not
enabled, then we don't need to depend on GENERIC_CLOCKEVENTS.

Not that we are trying to deceive in this case -- it's just another Kconfig
tangled web.

I think most architectures don't run into this because they select
either GENERIC_CLOCKEVENTS or ARCH_USES_GETTIMEOFFSET.
I thought that you need exactly one of the two (this is true on ARM),
but apparently ia64 is an exception.
I'm pretty sure that we don't ever need clocksource drivers on ia64,
so an easy workaround would be to make the entire file depend on
"!ARCH_USES_GETTIMEOFFSET && !IA64", but we can probably
do better than that.
The only architectures that use neither GENERIC_CLOCKEVENTS
nor ARCH_USES_GETTIMEOFFSET are frv, ia64 and some m68k
configurations. If we can show that none of those configurations
ever rely on clocksource drivers, we can simplify the
drivers/clocksource/Kconfig file a lot by using a
GENERIC_CLOCKEVENTS for the top-level option and removing
all the other dependencies in there.

I had a closer look at this, and found a third one: CONFIG_CLKSRC_NPS
should show the same bug as CONFIG_ARMV7M_SYSTICK and
CLKSRC_ST_LPC on the two 32-bit architectures, it just did not trigger
on ia64 because of the '!PHYS_ADDR_T_64BIT' dependency.
None of those three drivers makes any sense on any of the three
architectures though, and all other drivers directly or indirectly
depend on GENERIC_CLOCKEVENTS already, so simply making
the whole directory depend on GENERIC_CLOCKEVENTS
should solve this problem for good. I'll send a patch.
