Subject: [PATCH 0/8] kbuild: remove CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX and clean-up code


I got acknowledge to remove CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX entirely.
(https://lkml.org/lkml/2018/5/5/148)

Several tools can be cleaned-up.

Removing the CONFIG option makes VMLINUX_SYMBOL() no-op,
so this macro can be removed too.

VMLINUX_SYMBOL() and VMLINUX_SYMBOL_STR() are widely used,
so it will take some time to kill them entirely.
(I will send other patches later, splitting per-arch)



Masahiro Yamada (8):
  modpost: remove symbol prefix support
  genksyms: remove symbol prefix support
  kallsyms: remove symbol prefix support
  depmod.sh: remove symbol prefix support
  export.h: remove code for prefixing symbols with underscore
  kbuild: remove CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX
  vmlinux.lds.h: remove no-op macro VMLINUX_SYMBOL()
  checkpatch: remove VMLINUX_SYMBOL() check
