[PATCH V4 0/9] perf tools: kcore improvements

[Adrian Hunter]

Hi

Here are some improvements for using kcore (version 4).  There are 3
improvements:

	- validate that kcore matches the perf.data modules
	- workaround objdump difficulties with kcore
	- add kcore to the build-id cache

Changes in V4:
	perf tools: fix path unpopulated in machine__create_modules()
		Dropped because it has been applied
	perf buildid-cache: add ability to add kcore to the cache
		Tweaked Documentation/perf-buildid-cache.txt
	perf tools: add ability to find kcore in build-id cache
		Changed to check read access to /proc/kcore before
		skipping the buildid cache

Changes in V3:
	perf tools: workaround objdump difficulties with kcore
		change strncpy to strlcpy
	perf buildid-cache: add ability to add kcore to the cache
		change strncpy to strlcpy
	perf tools: add ability to find kcore in build-id cache
		change strncpy to strlcpy
Changes in V2:
	perf tools: fix buildid cache handling of kallsyms with kcore
		Dropped because it has been applied
	perf tools: fix path unpopulated in machine__create_modules()
		Use 'modules' pointer
