Please move HAVE_GENERIC_HARDIRQS to the config ARM entry, and remove
these:

config GENERIC_HARDIRQS
bool
default y

config GENERIC_HARDIRQS_NO__DO_IRQ
def_bool y

as they're in kernel/irq/Kconfig, and are visible if HAVE_GENERIC_HARDIRQS
is enabled.

Note also that should be a separate patch from adding HAVE_SPARSE_IRQ to
OMAP, as it's an independent but necessary change.

- This enables support for sparse irqs. This is useful in general
- as most CPUs have a fairly sparse array of IRQ vectors, which
- the irq_desc then maps directly on to. Systems with a high
- number of off-chip IRQs will want to treat this as
- experimental until they have been independently verified.
