Hello, This patchset fixes a segfault that occurs if 'm' appears in certain expressions before the modules symbol is defined. The problem is that m is rewritten to m && <modules symbol> already during parsing. Doing it in menu_finalize(), which runs after parsing, fixes the problem.
To aid the review and people trying to understand menu_finalize() in the future (including me), it also renames menu_check_dep() to rewrite_m() and adds comments to clarify the existing expression rewriting and dependency propagation logic. The changes have been tested for regressions using zconfdump(), Kconfiglib, and Valgrind.
