Re: [Xen-ia64-devel] [RFC][PATCH] [RESEND] support special guest optimisations in the hypervisor

[Dietmar Hahn <dietmar.hahn@xxxxxxxxxxxxxxxxxxx>]

Hi,

attached to this mail are 2 patches:
- opt_feature_xen.patch
  implements the new hypercall  __HYPERVISOR_opt_feature in the hypervisor.
- opt_feature_linux.patch
  implements the usage of the hypercall.

The xen - patch has real effects in vcpu_translate() on inserting identity 
mappings in the vhpt/tlb. I'am not sure about some performance impacts.
But without such a patch correct future protection key handling is impossible.

Please send comments or commit!
Thanks.

Dietmar
