Hi,
this patch fixes a few issue, so that make debug=y works (in Xen).
I think it is expected by Fedora.
Tested by booting dom0 (debug=y).
Tested by compiling without debug=y.

Previously, on SMP VTI-domain, Guest OS was responsible for syncing itc by
calling
Ia64_sync_itc, but the round trip may be very large on VTI domain, that may
cause guest itcs are not synced well and cause guest wall clock is not accurate.
This patch intends to fix this issue, when guest wants
Hi,
because the guest may modify interrupt_mask_addr and Xen runs at PL0, Xen
should not use this pointer.
This patch fixes a security issue and is a step toward shared_info remapping.
Tested by booting dom0+domU.

previously vpsr.pp was in tmp[8]. This creates a new field in struct
mapped_regs (without changing the layout).

If the guest could randomly (maliciously or accidentally)
change iva, Xen should re-validate it before using it (e.g.
to ensure that it is not in Xen address space, to ensure
it is not an I/O address etc.)
As you noticed, these checks are not performed.
Xen address space is protected
I have a question on priv_handle_op().
I changed the function so that xen/ia64 reflects itlb miss
to a domain
when xen/ia64 fails to read a bundle.
Xen/ia64 reflected dtlb miss before my change.
Is it correct to reflect dtlb miss?
No this was just a hack that worked. It does need

Hi, Alex
Thank you for your comments.
There's quite a bit changed in this patch that doesn't seem to be
covered by #ifdef XEN. Could you look into adding those in? Thanks,
I'm sorry.
I forgot adding #ifdef XEN when we change linx-xen/ for XEN.
I'll add #ifdef XEN.
Best Regards,

But I remade a big patch with ifdef, because I think we may leverage the

Would you object to the attached patch to clean up some of the

this stage, these don't seem necessary anymore, but I wanted to
