[PATCH] sparc: fix kgdb build failure due to context tracking

[Paul Gortmaker]

The following allmodconfig build failure is seen:

  CC      arch/sparc/kernel/kgdb_64.o
arch/sparc/kernel/kgdb_64.c: In function 'kgdb_trap':
arch/sparc/kernel/kgdb_64.c:162:7: error: implicit declaration of function 'exception_enter' [-Werror=implicit-function-declaration]
arch/sparc/kernel/kgdb_64.c:176:2: error: implicit declaration of function 'exception_exit' [-Werror=implicit-function-declaration]
cc1: all warnings being treated as errors

Bisection leads to commit 812cb83a56a908729c453a7db3fb2c262119bc9d
("sparc64: Implement HAVE_CONTEXT_TRACKING").  This commit failed
to include the proper header for the above two functions in this file.

Not in Linus's tree, it's already fixed there.

Sorry for the dup; was testing the init.h cleanups on
the weekend's rc7 tag and didn't notice the fix was in
after that...
