Subject: [PATCH] Revert "init/Kconfig: add option to disable kernel compression"
Date: Thu, 14 Nov 2013 21:43:47 -0800 [thread overview]
Message-ID: <1384494227-24029-1-git-send-email-hpa@zytor.com> (raw)
From: "H. Peter Anvin" <hpa@zytor.com>
This reverts commit 69f0554ec261fd686ac7fa1c598cc9eb27b83a80.
This patch breaks randconfig on at least the x86-64 architecture, and
most likely on others. There is work underway to support uncompressed
kernels in a generic way, but it looks like it will amount to
rewriting the support from scratch; see the LKML thread in the Link:
for info.
Therefore, revert this change and wait for the fix.
