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

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
