Could it be a config problem? My config file was from 'allnoconfig', I think, and has $ egrep 'SYSV|COMPAT' .config CONFIG_COMPAT=y # CONFIG_SYSVIPC is not set compat_sys_shmctl is in ipc/compat.c, and is enabled by CONFIG_SYSVIPC_COMPAT, which depends on CONFIG_SYSVIPC, which is off.
The reference to compat_sys_shmctl seems to be in ./arch/ia64/ia32/sys_ia32.c ./arch/ppc64/kernel/sys_ppc32.c ./arch/x86_64/ia32/ipc32.c ./arch/s390/kernel/compat_linux.c and appears to not be conditioned on CONFIG_SYSVIPC_COMPAT. Seems like linking problems are expected unless you turn on CONFIG_SYSVIPC and CONFIG_SYSVIPC_COMPAT.
I turned 'em on and am trying again. - Dan
