The patch looks good, but I'd suggest adding a oneline description
referencing that ia64 as a whole is removed.
I see that you created a couple of patches looking for __ia64__
but not CONFIG_IA64. If we get consensus on patch 1, we should
do that as well, let me know if you you want to add those or
would like me to help here.
I can probably do the same recursive check for removed Kconfig
options that I used for finding dead code after the boardfile
removal.

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)

Ok, got it. I missed that the first patch also removes
bits outside of arch/ia64.
