Subject: [PATCH 06/10] x86: Change NR_CPUS arrays in topology
Date: Sun, 13 Jan 2008 10:34:59 -0800 [thread overview]
Message-ID: <20080113183454.815670000@sgi.com> (raw)
In-Reply-To: <20080113183453.973425000@sgi.com>
[-- Attachment #1: NR_CPUS-arrays-in-topology --]
[-- Type: text/plain, Size: 1696 bytes --]
Change the following static arrays sized by NR_CPUS to
per_cpu data variables:
i386_cpu cpu_devices[NR_CPUS];
(And change the struct name to x86_cpu.)
