nbd: Don't use *_to_cpup() functions
The *_to_cpup() functions are not very useful, as they simply do a pointer dereference and then a *_to_cpu(). Instead use either: * ld*_*_p(), if the data is at an address that might not be correctly aligned for the load * a local dereference and *_to_cpu(), if the pointer is the correct type and known to be correctly aligned Signed-off-by: NPeter Maydell <peter.maydell@linaro.org> Message-Id: <1465570836-22211-1-git-send-email-peter.maydell@linaro.org> Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com> (cherry picked from commit 773dce3c) * context prereq for 7423f417Signed-off-by: NMichael Roth <mdroth@linux.vnet.ibm.com>
