FWIW, here is the list from a bit of scripting. Symbols that
are only defined in arch/ia64 but are referenced elsewhere are:

CONFIG_IA64
CONFIG_IA64_PAGE_SIZE_64KB
CONFIG_IA64_SGI_UV
CONFIG_IA64_DEBUG_CMPXCHG
CONFIG_MSPEC

Kconfig symbols that are only selected in arch/ia64 but
defined elsewhere are

CONFIG_ARCH_HAS_DMA_MARK_CLEAN
CONFIG_ARCH_TASK_STRUCT_ALLOCATOR
CONFIG_ARCH_TASK_STRUCT_ON_STACK
CONFIG_ARCH_THREAD_STACK_ALLOCATOR
CONFIG_GENERIC_IRQ_LEGACY

plus a few that have only one or two other places selecting them:

CONFIG_ARCH_CLOCKSOURCE_DATA (sparc64)
CONFIG_ARCH_MIGHT_HAVE_ACPI_PDC (x86)
CONFIG_ATA_NONSTANDARD (powerpc-maple)
CONFIG_FUNCTION_ALIGNMENT_32B (i386)
CONFIG_HUGETLB_PAGE_SIZE_VARIABLE (powerpc64)
CONFIG_ACPI_SYSTEM_POWER_STATES_SUPPORT (x86, loongarch)
CONFIG_ARCH_BINFMT_ELF_EXTRA_PHDRS (arm64, arch/um 32-bit)
CONFIG_HAVE_FUNCTION_DESCRIPTORS (ppc64be, parisc64)
CONFIG_HAVE_UNSTABLE_SCHED_CLOCK (parisc, x86)
CONFIG_HAVE_VIRT_CPU_ACCOUNTING (powerpc, s390)
CONFIG_SYSCTL_ARCH_UNALIGN_NO_WARN (arc, loongarch)
