[PATCH] frv: define MMU mode specific syscalls as 'cond_syscall' and clean up unneeded macros
For some architectures, a few syscalls are not linked in noMMU mode. In that case, the MMU depending syscalls are needed to be defined as 'cond_syscall'. For example, ARM architecture selectively links sys_mlock by the mode configuration. In case of FRV, it has been managed by #ifdef CONFIG_MMU macro in arch/frv/kernel/entry.S. However these conditional macros are just duplicates if they were defined as cond_syscall. Compilation test is done with FRV toolchains for both of MMU and noMMU mode. Signed-off-by: Hyok S.
