[PATCH V4 00/13] perf tools: add support for reading object code

[Adrian Hunter]

Hi

Here are some patches that add support for reading object code from vmlinux,
kernel modules and /proc/kcore.

Changes in V4:
	perf tools: make it possible to read object code from kernel modules
		Fix symbol adjustment for kernel modules
		Remove kallsyms' symbols when using a module's symbols
	perf tools: add kcore to the object code reading test
		Do not use static variables
	perf tools: put dso name in symbol annotation title
		New patch
	perf tools: remove nop at end of annotation
		New patch
	perf tools: add annotation call target name if it is missing
		New Patch


Changes in V3:
	perf tools: adjust the vmlinux symtab matches kallsyms test again
		New patch
	perf tools: add test for reading object code
		Fix error path by removing unnecessary perf_evlist__disable()
		Fix error path by setting evlist to NULL after deletion
		Fix sampling frequency by changing from 40000 to 4000
		Increase the number of operations performed by the "workload"
		to compensate for the lower sampling frequency

Changes in V2:
	Re-based on Arnaldo's tree's perf/core branch

	perf tools: add test for reading object code
		Use strchr in read_objdump_line()
		Remove unused return value of read_objdump_line()
		Fix double space before "cycles:u"
		Add missing perf_evlist__delete(evlist) in do_test_code_reading()
	perf tools: load kernel maps before using
		Correct spelling of "initialization" in commit message
	perf tools: add support for reading from /proc/kcore
		Do not test kallsyms filename for host buildid because
		/proc/kallsyms is always used if the dso buildid matches
		the host
	perf tools: add kcore to the object code reading test
		Remove redundant "else if (!have_kcore && try_kcore)" clause
