Right now it will just sort and position at the hottest line, i.e. the one where more samples were taken. It will be at the center of the screen and later TAB/shift-TAB will cycle thru the hottest lines.

ARM ELF files use symbols with special names $a, $t, $d to identify regions of ARM code, Thumb code and data within code sections. This can cause confusing output from the perf tools, especially for partially stripped binaries, or binaries containing user-added zero-sized symbols (which may occur in hand-written assembler which hasn't been fully annotated with .size directives). This patch filters out these symbols at load time.

As new TUI features get added the newt.c file is growing a lot and its name is growing misleading as an effort is being made to reduce the coupling with libnewt.

When cmd_record exits the whole perf binary will exit right after, so no need to traverse lots of complex data structures freeing them. Sticked a comment for leak detectives and for a experiment with obstacks to be performed so that we can speed up freeing that memory.

Only in verbose mode so as not to bloat struct symbol too much. The key used is '/', just like in vi, less, etc. More work is needed to allocate space on the symbol in a more clear way.

Comment in unregister_trace_probe() says probe_lock will be held when it gets called. However there is a case where it might called without the probe_lock being held. Also since we are traversing the probe_list and deleting an element from the probe_list, probe_lock should be held. This was first pointed in uprobes traceevent review by Frederic Weisbecker here.

The event__process function is useful in processing /proc/<pid>/maps. All of the functions that are called from event__process are defined in util/event.c. Though its defined in builtin-top.c, it could be reused for perf probe for uprobes. Hence moving it to util/event.c and exporting the function.

Fix buggy-looking code which unnecessarily adjusts the file offset fields read from /proc/*/maps. This may have gone unnoticed since the offset is usually 0 (and the logic in util/symbol.c may work incorrectly for other offset values). Commiter note: This fixes a bug introduced in 4af8b35d, there is no need to shift pgoff twice, the show_map_vma routine in fs/proc/task_mmu.c already converts it from the number of pages to the size in bytes, and that is what appears in /proc/PID/map.

If we receive two PERF_RECORD_EXIT for the same thread, we can end up reusing session->last_match and trying to remove the thread twice from the rb_tree, causing a segfault, so invalidade last_match in perf_session__remove_thread. Receiving two PERF_RECORD_EXIT for the same thread is a bug, but its a harmless one if we make the tool more robust, like this patch does.

Which is at perf_session__destroy_kernel_maps, counterpart to the perf_session__create_kernel_maps where the kmap structure is located, just after the vmlinux_maps. Make it also check if the kernel maps were actually created, which may not be the case if, for instance, perf_session__new can't complete due to permission problems in, for instance, a 'perf report' case, when a segfault will take place, that is how this was noticed. The problem was introduced in d65a458b, thus post .35. This also adds code to release guest machines as them are also created in perf_session__create_kernel_maps, so should be deleted on this newly introduced counterpart, perf_session__destroy_kernel_maps.
