- * This routine handles spinlock contention. It uses a non-standard calling

- * of this special convention, there are several restrictions:
- *
- * - do not use gp relative variables, this code is called from the kernel
- * and from modules, r1 is undefined.
- * - do not use stacked registers, the caller owns them.
- * - do not use the scratch stack space, the caller owns it.
- * - do not use any registers other than the ones listed below
- *
- * Inputs:
- * ar.pfs - saved CFM of caller
- * ar.ccv - 0 (and available for use)
- * r27 - flags from spin_lock_irqsave or 0. Must be preserved.
- * r28 - available for use.
- * r29 - available for use.
- * r30 - available for use.
- * r31 - address of lock, available for use.
- * b6 - return address
- * p14 - available for use.
- * p15 - used to track flag status.
- *
- * If you patch this code to use more registers, do not forget to update
