According to the imx27 documentation, fec has a 4 Kbyte memory space map. Moreover, the actual 16 Kbyte mapping overlaps the SCC (Security Controller) memory register space. So, we reduce the memory register space to 4 Kbyte.

ARM: fix missing syscall trace exit 2015-06-02T15:01:14+00:00 Russell King rmk+kernel@arm.linux.org.uk 2015-05-15T10:02:23+00:00 bd7044dfd8a3bcfd386d2cd7f0c01ba884a2cc88 commit 1b97937246d8b97c0760d16d8992c7937bdf5e6a upstream. Josh Stone reports: I've discovered a case where both arm and arm64 will miss a ptrace syscall-exit that they should report. If the syscall is entered without TIF_SYSCALL_TRACE set, then it goes on the fast path. It's then possible to have TIF_SYSCALL_TRACE added in the middle of the syscall, but ret_fast_syscall doesn't check this flag again. Fix this by always checking for a syscall trace in the fast exit path.
