I would try another patchset, to see other architecture guys' advice.
$ grep SYSVIPC_COMPAT arch -r
arch/x86/Kconfig:config SYSVIPC_COMPAT
arch/parisc/Kconfig:config SYSVIPC_COMPAT
arch/powerpc/Kconfig:config SYSVIPC_COMPAT
arch/arm64/Kconfig:config SYSVIPC_COMPAT
arch/riscv/Kconfig:config SYSVIPC_COMPAT
arch/s390/Kconfig:config SYSVIPC_COMPAT
arch/mips/Kconfig:config SYSVIPC_COMPAT
arch/mips/Kconfig: select SYSVIPC_COMPAT if SYSVIPC
arch/mips/Kconfig: select SYSVIPC_COMPAT if SYSVIPC
arch/sparc/Kconfig:config SYSVIPC_COMPAT
