#     scripts/mksysmap: Ignore prefixed KCFI symbols
#     
#     The (relatively) new KCFI feature in LLVM/Clang encodes type information
#     for C functions by generating symbols named __kcfi_typeid_<fname>, which
#     can then be referenced from assembly. However, some custom build rules
#     (e.g. nVHE or early PIE on arm64) use objcopy to add a prefix to all the
#     symbols in their object files, making mksysmap's ignore filter miss
#     those KCFI symbols.
#     
#     Therefore, explicitly list those twice-prefixed KCFI symbols as ignored.
#     
#     Alternatively, this could also be achieved in a less verbose way by
#     ignoring any symbol containing the string "__kcfi_typeid_". However,
#     listing the combined prefixes explicitly saves us from running the small
#     risk of ignoring symbols that should be kept.
