Subject: [PATCH] powerpc/xmon: Fix build failure for 8xx
With CONFIG_PPC_8xx and CONFIG_XMON set, kernel build fails with
arch/powerpc/xmon/xmon.c:1379:12: error: 'find_free_data_bpt' defined
but not used [-Werror=unused-function]
Fix it by enclosing find_free_data_bpt() inside #ifndef CONFIG_PPC_8xx.
Fixes: 30df74d67d48 ("powerpc/watchpoint/xmon: Support 2nd DAWR")
