Commite1b5bb6d12("consolidate cond_syscall and SYSCALL_ALIAS declarations") broke the h8300 build because it removed the duplicate SYMBOL_NAME() macro from arch/h8300/include/asm/linkage.h, and all the h8300 asm files include <asm/linkage.h> instead of <linux/linkage.h>: arch/h8300/kernel/entry.S: Assembler messages: arch/h8300/kernel/entry.S:158: Error: junk at end of line, first unrecognized character is `(' ... arch/h8300/kernel/syscalls.S: Assembler messages: arch/h8300/kernel/syscalls.S:6: Error: junk at end of line, first unrecognized character is `(' ... arch/h8300/lib/abs.S: Assembler messages: arch/h8300/lib/abs.S:12: Error: junk at end of line, first unrecognized character is `(' ... arch/h8300/lib/memcpy.S: Assembler messages: arch/h8300/lib/memcpy.S:13: Error: junk at end of line, first unrecognized character is `(' ... arch/h8300/lib/memset.S: Assembler messages: arch/h8300/lib/memset.S:13: Error: junk at end of line, first unrecognized character is `(' ... Commit126de6b20b("linkage.h: fix build breakage due to symbol prefix handling") broke it even more, by removing SYMBOL_NAME() and replacing it by __SYMBOL_NAME(). Commitf8ce1faf55("Merge tag 'modules-next-for-linus' of git://git.kernel.org/pub/scm/linuxkernel/git/rusty/linux") also removed __SYMBOL_NAME(), hidden in a merge conflict resolution. Hence, replace the use of SYMBOL_NAME() and SYMBOL_NAME_LABEL() in h8300 assembler sources by hardcoding the underscore symbol prefix, like other architectures (blackfin/metag) do. This allows to kill SYMBOL_NAME_LABEL(). Now <asm/linkage.h> becomes empty, and h8300 can be switched to asm-generic/linkage.h. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
