No, the test is for if the first (current) operation is crossing a page boundary, not if the NEXT one is... That''s why the code in this condition is using hvm_copy to fetch the data that is being accessed...

...version of the modified patches as is? The following list summarizes the changes. Hypervisor changes: o Add vmexit handling for the VMCALL instruction. This includes adjustments to hypercall arguments due to 32-bit vs. 64-bit calling conventions. o Modify copy_to_user/copy_from_user to use hvm_copy for HVM guests. o Modify grant table setup to properly map the grant table shared data for hvm guests. o Provide alternate headers for compiling 32-bit HVM guest code to interface with a 64-bit hypervisor. Many of the hypervisor structures used for hypercalls vary between 32-bit and 64-...

(The list appears to have eaten my previous attempt to send this. Apologies if you receive multiple copies.) The attached patches allow you to use paravirtualised network and block interfaces from fully virtualised domains, based on Intel''s patches from a few months ago. These are significantly faster than the equivalent ioemu devices, sometimes by more than an order of magnitude.
