2013-06-26Add a benchmark of strcpy.Christopher Ferris
List of all changes: - Add a strcpy benchmark. - Create a macro that is used to create all of the code for the main loop of the benchmark. - Fix the strcmp benchmark to use two buffers. The single buffer was an experiment that should not have been committed. It also crashes when a large alignment is used because it hard-coded an extra 2048 allocation regardless of the alignment chosen. - Modify the libc benchmarks to take the function to bench as a parameter. This will allow us to benchmark new potential libc optimizations by adding a single line to the function table list. Merge from internal master.

2013-06-24procrank: add support for only showing cached, noncached, or KSM pagesColin Cross
Add the -c, -C, and -k arguments to only show pages that are cached (backed by storage), non-cached (backed by ram or swap), or have been collapsed by KSM respectively. Change-Id: I707570ad406106b0aca230d18f9945901d193aca

2013-06-24librank: add command line argument for cached or non-cached pagesColin Cross
Add -c and -C command line arguments to only count pages that are cached (backed by storage) or non-cached (backed by ram or swap) respectively. Non-cached pages include all anonymous pages, as well as file backed pages that are mapped private and then modified. Change-Id: I95025d52f1c876b9c41fcbddaef5e95e32ebf307
2013-06-24libpagemap: add pm_map_usage_flagsColin Cross
Add pm_map_usage_flags, which is the same as pm_map_usage but only counts pages with the specified flags set. This can be used to only count "swapbacked" pages, which are pages that cannot be flushed back to disk without using swap. Change-Id: I6367555d9385502c797935849bb4221a8354e251

2013-06-24libpagemap: fix vss calculationColin Cross
pm_map_usage was not incrementing vss for pages that were in the process's map but not occupying a physical page. Move the vss increment above the check for present mappings. Change-Id: I2706e6fbcbfe7d70f10950333a486d690bc84d6c
2013-06-24libpagemap: fix reusing previous name for mappings with no nameColin Cross
Mappings that are not from a file do not have a name. The sscanf will read all of the fields up to the name, and then leave name untouched. This causes the previous name to be reused. Reset name to an empty string before each call to sscanf. Change-Id: Ib146732983eb074d0d4773be094efa0b672f5ed2

2013-05-22Add the memtrack utility.Christopher Ferris
This utility attempts to track the PSS usage of all of the processes in the system. It will keep track of the min/max/avg/last PSS for every process it has ever seen and dump that information when the program is terminated or when a USR1 or TSTP signal is sent to the process.

Missed the neon code in the copy bandwidths. Added guards and the functionality to indicate that these are neon based benchmarks. (cherry-pick of a67e53c2345eac337d24e4decaf4733c5314aff8.) Change-Id: If0fae051c47979eb243681a3c994222cefaae826
