* drivers: clean-up prom.h implicit includesRob Herring2013-10-091-0/+1
| | | | | | | | Powerpc is a mess of implicit includes by prom.h. Add the necessary explicit includes to drivers in preparation of prom.h cleanup. Signed-off-by: Rob Herring <rob.herring@calxeda.com> Acked-by: Grant Likely <grant.likely@linaro.org>
* drivers/virt: the Freescale hypervisor driver doesn't need to check MSR[GS]Timur Tabi2012-11-251-3/+0
| | | | | | | | | | | | | | | The MSR[GS] bit indicates whether the kernel is running in processor guest state mode, but such a check is unnecessary. The driver already checks for the /hypervisor node and the fsl,hv-version property, so it already knows that it's running under the Freescale hypervisor. There is nothing in the driver that inherently requires guest state, anyway. This fixes a break that can occur in some randconfig builds.

* drivers/virt: add ioctl for 32-bit compat on 64-bit to fsl-hv-managerMihai Caraman2011-10-141-0/+1
| | | | | | | | | Add ioctl to Freescale hypervisor management driver for 32-bit user-space applications running on 64-bit guests. Signed-off-by: Mihai Caraman <mihai.caraman@freescale.com> Acked-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* drivers/virt: add missing linux/interrupt.h to fsl_hypervisor.cTimur Tabi2011-07-221-0/+1
| | | | | | | | | fsl_hypervisor.c calls request_irq() but does not include linux/interrupt.h. Normally, the driver will compile without error, but it can fail on some configurations. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* drivers/virt: introduce Freescale hypervisor management driverTimur Tabi2011-07-081-0/+937
Add the drivers/virt directory, which houses drivers that support virtualization environments, and add the Freescale hypervisor management driver. The Freescale hypervisor management driver provides several services to drivers and applications related to the Freescale hypervisor: 1. An ioctl interface for querying and managing partitions 2. A file interface to reading incoming doorbells 3. An interrupt handler for shutting down the partition upon receiving the shutdown doorbell from a manager partition 4. A kernel interface for receiving callbacks when a managed partition shuts down.
