#     modpost: change the license of EXPORT_SYMBOL to bool type
#     
#     There were more EXPORT_SYMBOL types in the past. The following commits
#     removed unused ones.
#     
#      - f1c3d73e973c ("module: remove EXPORT_SYMBOL_GPL_FUTURE")
#      - 367948220fce ("module: remove EXPORT_UNUSED_SYMBOL*")
#     
#     There are 3 remaining in enum export, but export_unknown does not make
#     any sense because we never expect such a situation like "we do not know
#     how it was exported".
#     
#     If the symbol name starts with "__ksymtab_", but the section name
#     does not start with "___ksymtab+" or "___ksymtab_gpl+", it is not an
#     exported symbol.
#     
#     It occurs when a variable starting with "__ksymtab_" is directly defined:
#     
#        int __ksymtab_foo;
#     
#     Presumably, there is no practical issue for using such a weird variable
#     name (but there is no good reason for doing so, either).
#     
#     Anyway, that is not an exported symbol. Setting export_unknown is not
#     the right thing to do. Do not call sym_add_exported() in this case.
#     
#     With pointless export_unknown removed, the export type finally becomes
#     boolean (either EXPORT_SYMBOL or EXPORT_SYMBOL_GPL).
#     
#     I renamed the field name to is_gpl_only. EXPORT_SYMBOL_GPL sets it true.
#     Only GPL-compatible modules can use it.
#     
#     I removed the orphan comment, "How a symbol is exported", which is
#     unrelated to sec_mismatch_count. It is about enum export.
#     See commit bd5cbcedf446 ("kbuild: export-type enhancement to modpost.c")
