Evidently we need to change your new test in
drivers/usb/early/ehci-dbgp.c to:
#if
HPET_TN_FSB is not a proper mask bit; it merely toggles between MSI and
legacy interrupt delivery. The proper mask bit is HPET_TN_ENABLE, so
use both bits when (un)masking the interrupt.

Ingo,
Hold off on pulling this. Fengguang found some subtle bugs in David's
patches and I'm going to rebase (again) without them. I don't want to
hold up the rest of the patches for these few bugs.
I'll post a tip/perf/core-2 soon.

In virtualized environments, the CR0.TS management needed here can be a
lot slower than anticipated by the original authors of this code, which
particularly means that in such cases forcing the use of SSE- (or MMX-)
based implementations is not desirable - actual measurements should
