Subject: [PATCH] openrisc: Add prototype for show_registers to processor.h
When compiling with W=1 enabling -Wmissing-prototypes the compiler
warns:
arch/openrisc/kernel/traps.c:67:6: error: no previous prototype for 'show_registers' [-Werror=missing-prototypes]
Fix by adding the prototype to the appropriate header file and including
the header file in the appropriate C files.
Reported-by: Arnd Bergmann <arnd@arndb.de>
Closes: https://lore.kernel.org/linux-kernel/20230810141947.1236730-17-arnd@kernel.org/
