Registers
| register | value |
|---|---|
r27 | 237, the syscall number |
r4 | int mode |
r5 | const unsigned long *nmask |
r6 | unsigned long maxnode |
r4 | the return value |

r7 is the error flag and r4 then holds the positive error number.
This architecture was removed from the Linux kernel in Linux 4.17. The newest release with a syscall table here is Linux 4.16. The other removed architectures live on the historical architectures page.
