I'm read Bovet's "Understand the Linux Kernel"
and looked at the assembly routine setup_idt...
I noticed the assembly has SYMBOL_NAME
(its all over the place).
This is define in include/linux/linkage.h
to just:
#define SYMBOL_NAME(X) X
(this wasn't in Bovet's book).
What's the purpose?

IIRC, it's a holdover from the days when the kernel could be compiled in
a.out and ELF format. a.out prepends an underscore to all symbols,
whereas ELF does not.
