arch/sh/kernel/kprobes.c:52:16: warning: no previous prototype for 'arch_copy_kprobe' [-Wmissing-prototypes]
Although SH kprobes support was only merged in v2.6.28, it missed the
earlier removal of the arch_copy_kprobe() callback in v2.6.15.
Based on the powerpc part of commit 49a2a1b83ba6fa40 ("[PATCH] kprobes:
changed from using spinlock to mutex").
Fixes: d39f5450146ff39f ("sh: Add kprobes support.")

[ Upstream commit 553f7ac78fbb41b2c93ab9b9d78e42274d27daa9 ]
The SuperH BIOS earlyprintk code is protected by CONFIG_EARLY_PRINTK.
However, when this protection was added, it was missed that SuperH no
longer defines an EARLY_PRINTK config symbol since commit
e76fe57447e88916 ("sh: Remove old early serial console code V2"), so
BIOS earlyprintk can no longer be used.
Fix this by reviving the EARLY_PRINTK config symbol.
