Subject: [PATCH v2 01/28] kernel: Standardize vdso_datapage
Date: Thu, 29 Nov 2018 17:05:03 +0000 [thread overview]
Message-ID: <20181129170530.37789-2-vincenzo.frascino@arm.com> (raw)
In-Reply-To: <20181129170530.37789-1-vincenzo.frascino@arm.com>
In an effort to unify the common code for managing the vdso library in
between all the architectures that support it, this patch tries to
provide a common format for the vdso datapage.
As a result of this, this patch moves vdso_datapage.h from arm64 private
includes to general includes (include/vdso) and to avoid possible conflicts
replaces the header guard.
