[for-linus][PATCH 03/20] fgraph: Remove unused FGRAPH_MAX_INDEX

[Steven Rostedt <rostedt@kernel.org>]

From: Donggeun Yoo <donggeunyoo.kernel@gmail.com>

FGRAPH_MAX_INDEX has no user, and it expands to FGRAPH_INDEX_SIZE and
FGRAPH_RET_INDEX, neither of which is defined anywhere in the tree. It
was added in that form by commit 91c46b0aa917 ("function_graph:
Implement fgraph_reserve_data() and fgraph_retrieve_data()"), which
introduced the current data word layout under new names, so anything
referencing it would have failed to build ever since.

Remove it.
