Subject: Re: [RFC][PATCH] parisc: Add support for self-extracting kernel
Date: Mon, 21 Aug 2017 16:24:34 +0200 [thread overview]
Message-ID: <20170821142434.GA7148@p100.box> (raw)
In-Reply-To: <20170820085222.GA10546@p100.box>
The patch below is missing on top of the old patch I sent.
It's needed to avoid usage of fp registers.
This patch unbreaks booting the lzma variants (XZ, LZO, LZMA,...)
