2017-03-23PCI: thunder-pem: Add legacy firmware support for Cavium ThunderX host ↵Tomasz Nowicki1-2/+54
controller During early days of PCI quirks support, ThunderX firmware did not provide PNP0c02 node with PCI configuration space and PEM-specific register ranges. This means that for legacy FW we are not reserving these resources and cannot gather PEM-specific resources for further PEM initialization. To support already deployed legacy FW, calculate PEM-specific ranges and provide resources reservation as fallback scenario into PEM driver when we could not gather PEM reg base from ACPI tables.

2017-03-23Revert "i2c: mux: pca954x: Add ACPI support for pca954x"Andy Shevchenko1-27/+1
In ACPI world any ID should be carefully chosen and registered officially. The commit bbf9d262a147 seems did a wrong assumption because PCA is the registered PNP ID for "PHILIPS BU ADD ON CARD". I'm pretty sure this prefix has nothing to do with the driver in question. Moreover, newer ACPI specification has a support of _DSD method and special device IDs to allow drivers be enumerated via compatible string. The slight change to support this kind of enumeration will be added in sequential patch against pca954x.c. Revert the commit bbf9d262a147 for good.

2017-03-23KVM: kvm_io_bus_unregister_dev() should never failDavid Hildenbrand3-20/+29
No caller currently checks the return value of kvm_io_bus_unregister_dev(). This is evil, as all callers silently go on freeing their device. A stale reference will remain in the io_bus, getting at least used again, when the iobus gets teared down on kvm_destroy_vm() - leading to use after free errors. There is nothing the callers could do, except retrying over and over again. So let's simply remove the bus altogether, print an error and make sure no one can access this broken bus again (returning -ENOMEM on any attempt to access it).

2017-03-23mmc: sdhci-pci: Do not disable interrupts in sdhci_intel_set_powerAdrian Hunter1-0/+4
Disabling interrupts for even a millisecond can cause problems for some devices. That can happen when Intel host controllers wait for the present state to propagate. The spin lock is not necessary here. Anything that is racing with changes to the I/O state is already broken. The mmc core already provides synchronization via "claiming" the host. Although the spin lock probably should be removed from the code paths that lead to this point, such a patch would touch too much code to be suitable for stable trees. Consequently, for this patch, just drop the spin lock while waiting.

Disabling interrupts for even a millisecond can cause problems for some devices. That can happen when sdhci changes clock frequency because it waits for the clock to become stable under a spin lock.
