/* Note that the original Linux syscall restart convention required the
instruction immediately preceding SYSCALL to initialize $v0 with the
syscall number. Then if a restart triggered, $v0 would have been
clobbered by the syscall interrupted, and needed to be reinititalized.
The kernel would decrement the PC by 4 before switching back to the
user mode so that $v0 had been reloaded before SYSCALL was executed
again. This implied the place $v0 was loaded from must have been
preserved across a syscall, e.g. an immediate, static register, stack
slot, etc.
The convention was relaxed in Linux with a change applied to the kernel
GIT repository as commit 96187fb0bc30cd7919759d371d810e928048249d, that
first appeared in the 2.6.36 release. Since then the kernel has had
code that reloads $v0 upon syscall restart and resumes right at the
SYSCALL instruction, so no special arrangement is needed anymore.
For backwards compatibility with existing kernel binaries we support
the old convention by choosing the instruction preceding SYSCALL
carefully. This also means we have to force a 32-bit encoding of the
microMIPS MOVE instruction if one is used. */
