Subject: [PATCH AUTOSEL 5.17 027/149] powerpc/xive: Export XIVE IPI information for online-only processors.
Date: Fri, 1 Apr 2022 10:23:34 -0400 [thread overview]
Message-ID: <20220401142536.1948161-27-sashal@kernel.org> (raw)
In-Reply-To: <20220401142536.1948161-1-sashal@kernel.org>
From: Sachin Sant <sachinp@linux•ibm.com>
[ Upstream commit 279d1a72c0f8021520f68ddb0a1346ff9ba1ea8c ]
Cédric pointed out that XIVE IPI information exported via sysfs
(debug/powerpc/xive) display empty lines for processors which are
not online.
Switch to using for_each_online_cpu() so that information is
displayed for online-only processors.
