Many errors were observed while trying to build perf with gcc 10.
There were few patches which were merged on 5.4 stable which were missing in
our kernel repository, backporting the same here.

+Subject: perf cs-etm: Move definition of 'traceid_list' global variable from
+ header file
+
+commit 168200b6d6ea0cb5765943ec5da5b8149701f36a upstream.
+
+The variable 'traceid_list' is defined in the header file cs-etm.h,
+if multiple C files include cs-etm.h the compiler might complaint for
+multiple definition of 'traceid_list'.
+
+To fix multiple definition error, move the definition of 'traceid_list'
+into cs-etm.c.
+
+Fixes: cd8bfd8c973e ("perf tools: Add processing of coresight metadata")

+Subject: perf bench: Share some global variables to fix build with gcc 10
+
+commit e4d9b04b973b2dbce7b42af95ea70d07da1c936d upstream.
+
+Noticed with gcc 10 (fedora rawhide) that those variables were not being
+declared as static, so end up with:
+
+  ld: /tmp/build/perf/bench/epoll-wait.o:/git/perf/tools/perf/bench/epoll-wait.c:93: multiple definition of `end'; /tmp/build/perf/bench/futex-hash.o:/git/perf/tools/perf/bench/futex-hash.c:40: first defined here

+  make[4]: *** [/git/perf/tools/build/Makefile.build:145: /tmp/build/perf/bench/perf-in.o] Error 1
+
+Prefix those with bench__ and add them to bench/bench.h, so that we can
+share those on the tools needing to access those variables from signal
+handlers.

+Subject: libtraceevent: Fix build with binutils 2.35
+
+commit 39efdd94e314336f4acbac4c07e0f37bdc3bef71 upstream.
+
+In binutils 2.35, 'nm -D' changed to show symbol versions along with
+symbol names, with the usual @@ separator.  When generating
+libtraceevent-dynamic-list we need just the names, so strip off the
+version suffix if present.
