2013-10-21perf list: Show error if tracepoints not availablePekka Enberg
Tracepoints are not visible in "perf list" on Fedora 19 because regular users have no permission to /sys/kernel/debug by default. Show an error message so that the user knows about it instead of assuming that tracepoints are not supported on the system.

2013-10-16perf trace: Use vfs_getname hook if availableArnaldo Carvalho de Melo
Initially it tries to find a probe:vfs_getname that should be setup with: perf probe 'vfs_getname=getname_flags:65 pathname=result->name:string' or with slight changes to cope with code flux in the getname_flags code. In the future, if a "vfs:getname" tracepoint becomes available, then it will be preferred. This is not strictly required and more expensive method of reading the /proc/pid/fd/ symlink will be used when the fd->path array entry is not populated by a previous vfs_getname + open syscall ret sequence. As with any other 'perf probe' probe the setup must be done just once and the probe will be left inactive, waiting for users, be it 'perf trace' of any other tool.

2013-10-14perf buildid-cache: Add ability to add kcore to the cacheAdrian Hunter
kcore can be used to view the running kernel object code. However, kcore changes as modules are loaded and unloaded, and when the kernel decides to modify its own code. Consequently it is useful to create a copy of kcore at a particular time. Unlike vmlinux, kcore is not unique for a given build-id. And in addition, the kallsyms and modules files are also needed. The tool therefore creates a directory: ~/.debug/[kernel.kcore]/<build-id>/<YYYYmmddHHMMSShh> which contains: kcore, kallsyms and modules. Note that the copied kcore contains only code sections. See the kcore_copy() function for how that is determined. The tool will not make additional copies of kcore if there is already one with the same modules at the same addresses. Currently, perf tools will not look for kcore in the cache. That is addressed in another patch.

Turn it into 'debugging off' instead. - Same was the case for 'DEBUG=' - turn that into debug-off as well. - Pass in just a clean, sanitized 'DEBUG' value and get rid of the intermediate, unnecessary PERF_DEBUG variable.
