Include code to pre-construct mappings based on /proc, on system wide recording. Fix the existing code to properly fill out ->pid and ->tid. The PID should be the Thread Group ID (PIDTYPE_PID of task->group_leader) The TID should be the Thread ID (PIDTYPE_PID of task) Furthermore, change the default sorting of report to comm,dso for a better quick overview.

Perf record bails if no command argument is provided, so you can't use naked -a or -p to profile a running task or the whole box. Allow foreground profiling of an existing pid or the entire system.

recent userspace (F11) seems to already include the linux/unistd.h bits which means we cannot include the version in the kernel sources due to the header guards being the same. Ensure we include the kernel version first.

Allow specifying a pid instead of always fork+exec'ing a command. Because the PERF_EVENT_COMM and PERF_EVENT_MMAP events happened before we connected, we must synthesize them so that 'perf report' can get what it needs.
