[Linux-ia64] RAW dependency in ivt.S

Hi,

testing the kernel 2.4.18 I found a RAW dependency (for P8) in ivt.S in
entry alt_dtlb_miss. The lines are

cmp.ne p8,p0=r0,r23
(p8) br.cond.spnt page_fault

Why I'am not providing a (simple) patch: I' am wondering about taking
the privilege level for the decision about taking a page fault or
inserting the identity mapped TLB entry. For my understanding there
should be checked for region 7.
