Merge branch 'master' into for-next
Pull linus#master to merge PER_CPU_DEF_ATTRIBUTES and alpha build fix changes. As alpha in percpu tree uses 'weak' attribute instead of inline assembly, there's no need for __used attribute. Conflicts: arch/alpha/include/asm/percpu.h arch/mn10300/kernel/vmlinux.lds.S include/linux/percpu-defs.h

+ * The device-mapper userspace log module consists of a kernel component and
+ * a user-space component. The kernel component implements the API defined
+ * in dm-dirty-log.h. Its purpose is simply to pass the parameters and
+ * return values of those API functions between kernel and user-space.
+ *
+ * Below are defined the 'request_types' - DM_ULOG_CTR, DM_ULOG_DTR, etc.
+ * These request types represent the different functions in the device-mapper
+ * dirty log API. Each of these is described in more detail below.
+ *
+ * The user-space program must listen for requests from the kernel (representing
+ * the various API functions) and process them.
+ *
+ * User-space begins by setting up the communication link (error checking
+ * removed for clarity):
+ * fd = socket(PF_NETLINK, SOCK_DGRAM, NETLINK_CONNECTOR);
+ * addr.nl_family = AF_NETLINK;
+ * addr.nl_groups = CN_IDX_DM;
+ * addr.nl_pid = 0;
+ * r = bind(fd, (struct sockaddr *) &addr, sizeof(addr));
+ * opt = addr.nl_groups;
+ * setsockopt(fd, SOL_NETLINK, NETLINK_ADD_MEMBERSHIP, &opt, sizeof(opt));
+ *
+ * User-space will then wait to receive requests form the kernel, which it
+ * will process as described below. The requests are received in the form,
+ * ((struct dm_ulog_request) + (additional data)). Depending on the request
+ * type, there may or may not be 'additional data'. In the descriptions below,
+ * you will see 'Payload-to-userspace' and 'Payload-to-kernel'. The
+ * 'Payload-to-userspace' is what the kernel sends in 'additional data' as
+ * necessary parameters to complete the request. The 'Payload-to-kernel' is
+ * the 'additional data' returned to the kernel that contains the necessary
+ * results of the request. The 'data_size' field in the dm_ulog_request
+ * structure denotes the availability and amount of payload data.
