SubjectRE: [PATCH] Drivers: hv: vmbus: Fix virt_to_hvpfn() for X86_PAE
From: Dexuan Cui <> Sent: Tuesday, May 7, 2019 12:47 AM
> In the case of X86_PAE, unsigned long is u32, but the physical address type
> should be u64. Due to the bug here, the netvsc driver can not load
> successfully, and sometimes the VM can panic due to memory corruption (the
> hypervisor writes data to the wrong location).
