+socket type mapping wrong for mips app-level emulation
+
+linux-user/syscall.c's do_socket function contains socket type remapping to work around the nonsensically-permuted MIPS socket types. However, it fails to account for the SOCK_NONBLOCK and SOCK_CLOEXEC flags that may be or'd onto the type. Thus, a call from the application such as:
+
+socket(AF_INET, SOCK_STREAM, IPPROTO_TCP)
+
+will fail to have the type permutation performed, and will be passed to the system as:
+
+socket(AF_INET, SOCK_DGRAM, IPPROTO_TCP)
+
+resulting in EPROTONOSUPPORT.
+
+To fix this, the flag bits should be masked off of the type before the permutation. They also need remapping themselves (since MIPS uses different values for these flags bits).
