I assume the following code (in ia64_set_kernel_registers ) should restore correct GP value. ia64_set_kernel_registers: ... ;; ld8 r1=[temp4] // OS GP from SAL OS state -- Thanks, Luming - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
