[Xen-devel] About getting guest pfn number from virtual address



Hi, 
I find that the shadow page fault entry function is : sh_page_fault. 
It has three parameters: struct vcpu *v, unsigned long va and struct 
cpu_user_regs *regs. 

I have two questions here: 
1. The "unsigned long va" means the virtual address of the guest? 
2. How can I get the physical frame number (PFN) from this va variable? 
Thanks.

Best,
