* mm: join struct fault_env and vm_faultJan Kara2016-12-141-1/+1
| | | | | | | | | | | | | | | | | | | Currently we have two different structures for passing fault information around - struct vm_fault and struct fault_env. DAX will need more information in struct vm_fault to handle its faults so the content of that structure would become event closer to fault_env. Furthermore it would need to generate struct fault_env to be able to call some of the generic functions. So at this point I don't think there's much use in keeping these two structures separate. Just embed into struct vm_fault all that is needed to use it for both purposes.

| * dm crypt: add ability to use keys from the kernel key retention serviceOndrej Kozina2016-12-081-1/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel key service is a generic way to store keys for the use of other subsystems. Currently there is no way to use kernel keys in dm-crypt. This patch aims to fix that. Instead of key userspace may pass a key description with preceding ':'. So message that constructs encryption mapping now looks like this: <cipher> [<key>|:<key_string>] <iv_offset> <dev_path> <start> [<#opt_params> <opt_params>] where <key_string> is in format: <key_size>:<key_type>:<key_description> Currently we only support two elementary key types: 'user' and 'logon'. Keys may be loaded in dm-crypt either via <key_string> or using classical method and pass the key in hex representation directly. dm-crypt device initialised with a key passed in hex representation may be replaced with key passed in key_string format and vice versa.

In this case, additional information has to be made available to the kernel (the scheduler in particular) for it to be aware of such differences and take decisions accordingly. Therefore, this patch aims at standardizing cpu capacities device tree bindings for ARM platforms. Bindings define cpu capacity-dmips-mhz parameter, to allow operating systems to retrieve such information from the device tree and initialize related kernel structures, paving the way for common code in the kernel to deal with heterogeneity.

Although XER is part of the CPU state that gets checkpointed, the code that does this saving and restoring doesn't save/restore XER. This fixes it by saving and restoring the XER. To allow userspace to read/write the checkpointed XER value, we also add a new ONE_REG specifier. The visible effect of this bug is that the guest may see its XER value being corrupted when it uses transactions.

Define it to be the first bytes of the bitstream. Each driver gets to set how many bytes (at most) it wants to see. Short bitstreams will be passed through as-is, while long ones will be truncated. The intent is to allow drivers to peek at the header before the transfer actually starts.

This change is expected to bring little, if any, pain. An FPGA image file will have particulars that affect how the image is programmed to the FPGA. One example is that current 'flags' currently has one bit which shows whether the FPGA image was built for full reconfiguration or partial reconfiguration. Another example is timeout values for enabling or disabling the bridges in the FPGA. As the complexity of the FPGA design increases, the bridges in the FPGA may take longer times to enable or disable. This patch documents the change in the FPGA Manager API functions, replacing the 'u32 flag' parameter with a pointer to struct fpga_image_info.
