  "message": "CONFIG_SYMBOL_PREFIX: cleanup.\n\nWe have CONFIG_SYMBOL_PREFIX, which three archs define to the string\n\"_\".  But Al Viro broke this in \"consolidate cond_syscall and\nSYSCALL_ALIAS declarations\" (in linux-next), and he\u0027s not the first to\ndo so.\n\nUsing CONFIG_SYMBOL_PREFIX is awkward, since we usually just want to\nprefix it so something.  So various places define helpers which are\ndefined to nothing if CONFIG_SYMBOL_PREFIX isn\u0027t set:\n\n1) include/asm-generic/unistd.h defines __SYMBOL_PREFIX.\n2) include/asm-generic/vmlinux.lds.h defines VMLINUX_SYMBOL(sym)\n3) include/linux/export.h defines MODULE_SYMBOL_PREFIX.\n4) include/linux/kernel.h defines SYMBOL_PREFIX (which differs from #7)\n5) kernel/modsign_certificate.S defines ASM_SYMBOL(sym)\n6) scripts/modpost.c defines MODULE_SYMBOL_PREFIX\n7) scripts/Makefile.lib defines SYMBOL_PREFIX on the commandline if\n   CONFIG_SYMBOL_PREFIX is set, so that we have a non-string version\n   for pasting.\n\n(arch/h8300/include/asm/linkage.h defines SYMBOL_NAME(), too).\n\nLet\u0027s solve this properly:\n1) No more generic prefix, just CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX.\n2) Make linux/export.h usable from asm.\n3) Define VMLINUX_SYMBOL() and VMLINUX_SYMBOL_STR().\n4) Make everyone use them.\n\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nReviewed-by: James Hogan \u003cjames.hogan@imgtec.com\u003e\nTested-by: James Hogan \u003cjames.hogan@imgtec.com\u003e (metag)\n",
