MIPS: Compat: Fix build error if CONFIG_MIPS32_COMPAT but no compat ABI.
In that case nor __NR_seccomp_*_32 symbols will be defined in <asm/unistd.h> so the attempt to use it in kernel.seccomp.c will fail with: kernel/seccomp.c:565:2: error: '__NR_seccomp_read_32' undeclared here (not in a function) __NR_seccomp_read_32, __NR_seccomp_write_32, __NR_seccomp_exit_32, __NR_seccomp_sigreturn_32, ^ kernel/seccomp.c:565:24: error: '__NR_seccomp_write_32' undeclared here (not in a function) __NR_seccomp_read_32, __NR_seccomp_write_32, __NR_seccomp_exit_32, __NR_seccomp_sigreturn_32, ^ kernel/seccomp.c:565:47: error: '__NR_seccomp_exit_32' undeclared here (not in a function) __NR_seccomp_read_32, __NR_seccomp_write_32, __NR_seccomp_exit_32, __NR_seccomp_sigreturn_32, ^ kernel/seccomp.c:565:69: error: '__NR_seccomp_sigreturn_32' undeclared here (not in a function) __NR_seccomp_read_32, __NR_seccomp_write_32, __NR_seccomp_exit_32, __NR_seccomp_sigreturn_32, Solved by changing the compat ABIs in kconfig to select MIPS32_COMPAT directly. This also means the user no longer has to select MIPS32_COMPAT before being able to see the ABI options. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
