78	The kernel would decrement the PC by 4 before switching back to the
79	user mode so that $v0 had been reloaded before SYSCALL was executed
80	again. This implied the place $v0 was loaded from must have been
81	preserved across a syscall, e.g. an immediate, static register, stack
82	slot, etc.
83
84	The convention was relaxed in Linux with a change applied to the kernel
85	GIT repository as commit 96187fb0bc30cd7919759d371d810e928048249d, that
86	first appeared in the 2.6.36 release. Since then the kernel has had
87	code that reloads $v0 upon syscall restart and resumes right at the
88	SYSCALL instruction, so no special arrangement is needed anymore.
89
90	For backwards compatibility with existing kernel binaries we support
91	the old convention by choosing the instruction preceding SYSCALL
92	carefully. This also means we have to force a 32-bit encoding of the

72	syscall number. Then if a restart triggered, $v0 would have been
73	clobbered by the syscall interrupted, and needed to be reinititalized.
74	The kernel would decrement the PC by 4 before switching back to the
75	user mode so that $v0 had been reloaded before SYSCALL was executed
76	again. This implied the place $v0 was loaded from must have been
77	preserved across a syscall, e.g. an immediate, static register, stack
78	slot, etc.
79
80	The convention was relaxed in Linux with a change applied to the kernel
81	GIT repository as commit 96187fb0bc30cd7919759d371d810e928048249d, that
82	first appeared in the 2.6.36 release. Since then the kernel has had
83	code that reloads $v0 upon syscall restart and resumes right at the
84	SYSCALL instruction, so no special arrangement is needed anymore.
85
86	For backwards compatibility with existing kernel binaries we support
87	the old convention by choosing the instruction preceding SYSCALL
88	carefully. This also means we have to force a 32-bit encoding of the
89	microMIPS MOVE instruction if one is used. */
