Subject: [PATCH] powerpc/xmon: Fix build failure for 8xx
Date: Mon, 30 Nov 2020 09:14:06 +0530	[thread overview]
Message-ID: <20201130034406.288047-1-ravi.bangoria@linux.ibm.com> (raw)

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.

Reported-by: kernel test robot <lkp@intel.com>
Fixes: 30df74d67d48 ("powerpc/watchpoint/xmon: Support 2nd DAWR")
