Subject: [PATCH v15 02/13] powerpc/32: Fix CONFIG_VIRT_CPU_ACCOUNTING_NATIVE for 40x/booke
Date: Thu, 31 Jan 2019 10:08:46 +0000 (UTC)	[thread overview]
Message-ID: <da718ce0da4303de0197b46570680843a188f216.1548852243.git.christophe.leroy@c-s.fr> (raw)
In-Reply-To: <cover.1548852242.git.christophe.leroy@c-s.fr>

40x/booke have another path to reach 3f from transfer_to_handler,
make sure it also calls ACCOUNT_CPU_USER_ENTRY() when
CONFIG_VIRT_CPU_ACCOUNTING_NATIVE is selected.
