h8300 SYMBOL_NAME() breakage

Commit e1b5bb6d1236d4ad2084c53aa83dde7cdf6f8eea ("consolidate cond_syscall
and SYSCALL_ALIAS declarations") broke the h8300 build because it removed
the duplicate SYMBOL_NAME from arch/h8300/include/asm/linkage.h, and all
the h8300 asm files include <asm/linkage.h> instead of <linux/linkage.h>.
(yes, this was in -next).

Commit 126de6b20bfb82cc19012d5048f11f339ae5a021 ("linkage.h: fix build
breakage due to symbol prefix handling") broke it even more, by removing
SYMBOL_NAME() and replacing it by __SYMBOL_NAME().

Commit f8ce1faf55955de62e0a12e330c6d9a526071f65 ("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.

Interestingly, commit b92021b09df70c1609e3547f3d6128dd560be97f
("CONFIG_SYMBOL_PREFIX: cleanup.") mentions
"arch/h8300/include/asm/linkage.h defines SYMBOL_NAME(), too", so (some)
people should have been aware of the issue?

BTW, arch/h8300/include/asm/linkage.h still has

    #undef SYMBOL_NAME_LABEL
    #define SYMBOL_NAME_LABEL(_name_) _##_name_##:
    #endif

How should this be fixed?
  - Re-add SYMBOL_NAME() to arch/h8300/include/asm/linkage.h?
  - Kill SYMBOL_NAME() and SYMBOL_NAME_LABEL(), and hardcode the
underscores in the h8300 asm sources?
  - Anything else?
I didn't follow the whole symbol prefix discussion that closely.

Thaks for your suggestions?
