4Subject: [PATCH] Clean usage of void pointers to access symbols
5
6Void pointers have been used to access linker symbols, by declaring an
7extern pointer, then taking the address of it. This limits symbols
8values to aligned pointer values. To remove this restriction an
9IMPORT_SYM macro has been introduced, which declares it as a char
10pointer and casts it to the required type.
