Subject: [PATCH 2/3] powerpc/mm/64s: Fix no previous prototype warning
Date: Thu, 11 Feb 2021 00:08:03 +1100 [thread overview]
Message-ID: <20210210130804.3190952-2-mpe@ellerman.id.au> (raw)
In-Reply-To: <20210210130804.3190952-1-mpe@ellerman.id.au>
As reported by lkp:
arch/powerpc/mm/book3s64/radix_tlb.c:646:6: warning: no previous
prototype for function 'exit_lazy_flush_tlb'
Fix it by moving the prototype into the existing header.
Fixes: 032b7f08932c ("powerpc/64s/radix: serialize_against_pte_lookup IPIs trim mm_cpumask")
Reported-by: kernel test robot <lkp@intel.com>
