x86: rate-limit logging in do_xen{oprof,pmu}_op()
|
|
|
|
Some of the sub-ops are acessible to all guests, and hence should be
|
|
rate-limited. In the xenoprof case, just like for XSA-146, include them
|
|
only in debug builds. Since the vPMU code is rather new, allow them to
|
|
be always present, but downgrade them to (rate limited) guest messages.
|
|
|
|
This is XSA-152.
