Subject: [PATCH v2 1/4] init: provide a generic free_initmem implementation
Date: Mon, 18 Feb 2019 20:41:22 +0200 [thread overview]
Message-ID: <1550515285-17446-2-git-send-email-rppt@linux.ibm.com> (raw)
In-Reply-To: <1550515285-17446-1-git-send-email-rppt@linux.ibm.com>
For most architectures free_initmem just a wrapper for the same
free_initmem_default(-1) call.
Provide that as a generic implementation marked __weak.
