From 4afd58e14dd415e456fd236755373f52e6055ec7 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 13 May 2019 17:18:34 -0700 Subject: initramfs: provide a generic free_initrd_mem implementation For most architectures free_initrd_mem just expands to the same free_reserved_area call. Provide that as a generic implementation marked __weak.
