Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf fixes from Ingo Molnar:
"Tooling fixes, mostly related to the KASLR fallout, but also other
fixes"
* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
perf buildid-cache: Check relocation when checking for existing kcore
perf tools: Adjust kallsyms for relocated kernel
perf tests: No need to set up ref_reloc_sym
perf symbols: Prevent the use of kcore if the kernel has moved
perf record: Get ref_reloc_sym from kernel map
perf machine: Set up ref_reloc_sym in machine__create_kernel_maps()
perf machine: Add machine__get_kallsyms_filename()
perf tools: Add kallsyms__get_function_start()
perf symbols: Fix symbol annotation for relocated kernel
perf tools: Fix include for non x86 architectures
perf tools: Fix AAAAARGH64 memory barriers
perf tools: Demangle kernel and kernel module symbols too
perf/doc: Remove mention of non-existent set_perf_event_pending() from design.txt
