r27222, the syscall number
r4unsigned long addr
r5unsigned long len
r6unsigned long prot
r7unsigned long flags
r8unsigned long fd
r9unsigned long pgoff
r4the return value

Then run syscall to enter the kernel.

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.
