recordmcount: support >64k sections
[ Upstream commit 4ef57b21d6fb49d2b25c47e4cff467a0c2c8b6b7 ]
When compiling a kernel with Clang and LTO, we need to run
recordmcount on vmlinux.o with a large number of sections, which
currently fails as the program doesn't understand extended
section indexes. This change adds support for processing binaries
with >64k sections.
