Subject: [PATCH 4/5] x86/microcode/intel: Fix allocation size of struct ucode_patch
Date: Mon, 9 Jan 2017 12:41:46 +0100 [thread overview]
Message-ID: <20170109114147.5082-5-bp@alien8.de> (raw)
In-Reply-To: <20170109114147.5082-1-bp@alien8.de>
From: Junichi Nomura <j-nomura@ce.jp.nec.com>
We allocate struct ucode_patch here. @size is the size of microcode data
and used for kmemdup() later in this function.

Fixes: 06b8534cb728 ("x86/microcode: Rework microcode loading")
