2014-09-27block: Add a disk flag to block integrity profileMartin K. Petersen1-0/+8
So far we have relied on the app tag size to determine whether a disk has been formatted with T10 protection information or not. However, not all target devices provide application tag storage. Add a flag to the block integrity profile that indicates whether the disk has been formatted with protection information. Signed-off-by: Martin K.

2014-09-27block: Remove integrity tagging functionsMartin K. Petersen1-34/+0
None of the filesystems appear interested in using the integrity tagging feature. Potentially because very few storage devices actually permit using the application tag space.

2014-09-27block: Replace bi_integrity with bi_specialMartin K. Petersen1-5/+5
For commands like REQ_COPY we need a way to pass extra information along with each bio. Like integrity metadata this information must be available at the bottom of the stack so bi_private does not suffice. Rename the existing bi_integrity field to bi_special and make it a union so we can have different bio extensions for each class of command. We previously used bi_integrity != NULL as a way to identify whether a bio had integrity metadata or not. Introduce a REQ_INTEGRITY to be the indicator now that bi_special can contain different things. In addition, bio_integrity(bio) will now return a pointer to the integrity payload (when applicable).

2014-09-26bpf: introduce BPF syscall and mapsAlexei Starovoitov1-0/+39
BPF syscall is a multiplexor for a range of different operations on eBPF. This patch introduces syscall with single command to create a map. Next patch adds commands to access maps. 'maps' is a generic storage of different types for sharing data between kernel and userspace. Userspace example: /* this syscall wrapper creates a map with given type and attributes * and returns map_fd on success. * use close(map_fd) to delete the map */ int bpf_create_map(enum bpf_map_type map_type, int key_size, int value_size, int max_entries) { union bpf_attr attr = { .map_type = map_type, .key_size = key_size, .value_size = value_size, .max_entries = max_entries }; return bpf(BPF_MAP_CREATE, &attr, sizeof(attr)); } 'union bpf_attr' is backwards compatible with future extensions.

If an MFD device is backed by ACPI namespace, we should allow subdevice drivers to access their corresponding ACPI companion devices through normal means (e.g using ACPI_COMPANION()). This patch adds such support to the MFD core. If the MFD parent device does not specify any ACPI _HID/_CID for the child device, the child device will share the parent ACPI companion device. Otherwise the child device will be assigned with the corresponding ACPI companion, if found in the namespace below the parent.
