What would we need to do to get all architectures using the new

We would change the various compat_sys_ipc functions (mips, powerpc,
s390, sparc, x86) to call the new functions instead of the existing
ones, and test each architecture. For parisc, we might not
actually need the either version, but I'd have to take a closer look
to be sure.
Regarding the implementation: rather than patching the header
files, it would be more conventional (and arguably better) to add
select ARCH_WANT_OLD_COMPAT_IPC
to arch/*/Kconfig, then use CONFIG_ARCH_WANT_OLD_COMPAT_IPC.
Yes.
