Hi,

while I was trying to understand the trap handler in
linux-2.6-xen-sparse/arch/ia64/xen/xenivt.S
I saw the lines 205 ff:

#ifdef CONFIG_XEN
        mov r24=r8
        mov r8=r18
        ;;
(p10)   XEN_HYPER_ITC_D
        ;;
(p11)   XEN_HYPER_ITC_I
        ;;
        mov r8=r24
        ;;
#else
(p10)   itc.i r18                               // insert the instruction TLB 
entry
(p11)   itc.d r18                               // insert the data TLB entry
#endif

May it be that XEN_HYPER_ITC_D and XEN_HYPER_ITC_I are in the reverse order?

Dietmar.
