Subject: x86: make debug output consistent in hvm_set_callback_via

|
|
The unconditional printks in the switch statement of the
|
|
hvm_set_callback_via function results in Xen log spam in non debug
|
|
versions of Xen. The printks are for debug output only so conditionally
|
|
compile the entire switch statement on debug versions of Xen only.
|
|
|
|
This is XSA-169.
