[Xen-devel] [PATCH 1/2] trace: Use correct trace class for power management changes.

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

Previous to this patch we would see in the trace file:

CPU28  1753503175371 (+    8496)  unknown (0x0000000000801002)  [ 0x00000004

instead of:
CPU28  1753503175371 (+    8496)  cpu_idle_entry  [ C0 -> C4, acpi_pm_tick = 
1096328344, expected = 929us, predicted = 10214us ]
CPU28  1753505321239 (+ 2145868)  cpu_idle_exit   [ C4 -> C0, acpi_pm_tick =

1104273452, irq = 171 0 0 0 ]

The patch that added the cpu_idle_[entry|exit] was using the
TRC_HW_IRQ class (0x00802000) instead of TRC_HW_PM (0x00801000)
as a base.
