*	acpi_piix4: Re-define PCI hotplug eject register read	Alex Williamson	2012-04-15	1	-2/+10
\| \| \| \| \| \| \| \| \| \| \| \|	The PCI hotplug eject register has always returned 0, so let's redefine it as a hotplug feature register. The existing model of using separate up & down read-only registers and an eject via write to this register becomes the base implementation. As we make use of new interfaces we'll set bits here to allow the BIOS and AML implementation to optimize for the platform implementation.

*	acpi_piix4: Remove PCI_RMV_BASE write code	Alex Williamson	2012-04-15	1	-1/+1
\| \| \| \| \| \| \| \|	Clarify this register as read-only and remove write code. No change in existing behavior. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
*	acpi_piix4: Disallow write to up/down PCI hotplug registers	Alex Williamson	2012-04-15	1	-2/+2
\| \| \| \| \| \| \| \| \| \|	The write side of these registers is never used and actually can't be used as defined because any read/modify/write sequence from the guest potentially races with qemu. Drop the write support and define these as read-only registers. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
