i came across this while playing with hdparm

========================================
the bios on this machine (hp ze4423ea laptop) is horribly broken
without 'pci=noacpi pci=usepirqmask' i get:
Jan 18 13:10:52 hades kernel: ACPI: No IRQ known for interrupt pin A
of device 0
000:00:10.0
i played with hdparm cause the whole cpu time is eaten by io-wait
whenever there is disk-io
in this state everything slows down to a crawl and the box is nearly
unusable while its swapping
changing unmask irq or switching from dma to non dma mode doesnt
change anything

Ugh, this is due to calling system_bus_clock() from within an interrupt.
Is there any good reason to do this? Can't we just cache the bus speed
in the local device structure if we really have to do this from within
an interrupt?
thanks,

ide_init() always initializes system_bus_speed variable
so system_bus_clock() should never call ide_system_bus_speed()
and no driver is calling ide_system_bus_speed() directly.
Bug was that if no IDE kernel parameter was given during boot
system_bus_speed will be zeroed in init_ide_data().
This patch should fix the problem
(as a bonus -> no need to zero these variables they are static).
