Registers

registervalue
r10234, the syscall number
r0unsigned long start
r1unsigned long size
r2unsigned long prot
r3unsigned long pgoff
r4unsigned long flags
r0the return value

Then run swint1 to enter the kernel.

The kernel uses r1 to signal an error.

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.
