[Xen-ia64-devel] [PATCH]: clear the key part of cr.itir

[Dietmar Hahn <dietmar.hahn@xxxxxxxxxxxxxxxxxxx>]

Hi,

the attached patch clears the key part of the cr.itir register before itc.X in 
alt_dtlb_miss(), alt_itlb_miss() and frametable_miss().
This is in preparation of using protection keys. The plan is to use the key 
0x0 for the hypervisor.
The patch doesn't change the footprint of the trap handlers.
Please send comments or commit.
Thanks.

Dietmar.
