Subject: [PATCH 03/11] x86/MCE: avoid effectively open-coding xmalloc_array()
Date: Thu, 8 Apr 2021 14:17:58 +0200 [thread overview]
Message-ID: <47101cea-a856-3921-dd19-89ce766aaaeb@suse.com> (raw)
In-Reply-To: <a3fef3b0-c9f3-208e-3728-62ca9cff70ba@suse.com>
There is a difference in generated code: xmalloc_bytes() forces
SMP_CACHE_BYTES alignment. I think we not only don't need this here, but
actually don't want it.
