Subject: [RFC PATCH v3 01/12] powerpc/64: Don't provide time functions in compat VDSO32
Date: Mon, 13 Jan 2020 17:08:39 +0000 (UTC) [thread overview]
Message-ID: <f64d31871148a75db9b6aeec7fbad0e3ea1b0737.1578934751.git.christophe.leroy@c-s.fr> (raw)
In-Reply-To: <cover.1578934751.git.christophe.leroy@c-s.fr>
In order to allow use of generic C VDSO, remove time functions
from the 32 bits VDSO on PPC64.
This (temporary) removal is needed because powerpc kernel C headers
are not prepared for building 32 bits code on PPC64.
