Yes,  I have enabled :

#
# Processor Type
#
CONFIG_CPU_V6=y
CONFIG_CPU_V6K=y
CONFIG_CPU_32v6=y
CONFIG_CPU_32v6K=y

and

# TI OMAP/AM/DM/DRA Family
#
CONFIG_ARCH_OMAP2=y
CONFIG_ARCH_OMAP2PLUS=y

and

#
# MX31 platforms:
#
CONFIG_MACH_MX31ADS=y
CONFIG_MACH_MX31LILLY=y
CONFIG_MACH_MX31LITE=y
CONFIG_MACH_PCM037=y
CONFIG_MACH_PCM037_EET=y
CONFIG_MACH_MX31_3DS=y

Most ARM11 implementations are ARMv6k, which has support for the instruction,
but the older ARMv6 (without k) does not. From your description, I assume
you only tested with ARMv6k, not ARMv6. Please enable the OMAP2 and IMX31
platforms to test ARMv6.
