Revert "HACK stay compatible with the emulated TLS register HACK"
This reverts commit f00c8f71dae5a16b7fab0e77fc8b32feac9d38a7.
We need enable the SWP() emulation which depend on removing domain switching
on ARM kernel. Emulated TLS register requires the user space page mapped as
R/W in kernel which requires domain swtiching. Remove this patch becasue the
ARM V7 has HW TLS register.
