2017-02-20ipmi: bt-bmc: Use a regmap for register accessAndrew Jeffery
The registers for the bt-bmc device live under the Aspeed LPC controller. Devicetree bindings have recently been introduced for the LPC controller where the "host" portion of the LPC register space is described as a syscon device. Future devicetrees describing the bt-bmc device should nest its node under the appropriate "simple-mfd", "syscon" compatible node. This change allows the bt-bmc driver to function with both syscon and non-syscon- based devicetree descriptions by always using a regmap for register access, either retrieved from the parent syscon device or instantiated if none exists.

2017-02-20nfp: allow application firmware to limit number of SR-IOV VFsJakub Kicinski
Some application firmware projects may choose to limit the number of VFs available below what is specified in PCI capability to be able to reuse the PCIe interface resources. There may also be projects which use cases don't require SR-IOV support at all and therefore don't want to spend time implementing/testing it. Check nfd_vf_cfg_max_vfs firmware symbol to see if application firmware is reporting how many VFs it supports. This mechanism is an opt-in, if symbol is not present we will only look at the PCI capability values. Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S.

The Makefile in drivers/s390 has: obj-y += cio/ block/ char/ crypto/ net/ scsi/ virtio/ and the Makefile in crypto/ has: ap-objs := ap_bus.o ap_card.o ap_queue.o meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit. Also note that MODULE_ALIAS is a no-op for non-module builds. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.
