Subject: [PATCH 5.13 11/24] perf/x86/intel/pt: Fix mask of num_address_ranges
Date: Mon,  6 Sep 2021 14:55:40 +0200	[thread overview]
Message-ID: <20210906125449.483125622@linuxfoundation.org> (raw)
In-Reply-To: <20210906125449.112564040@linuxfoundation.org>

From: Xiaoyao Li <xiaoyao.li@intel.com>

[ Upstream commit c53c6b7409f4cd9e542991b53d597fbe2751d7db ]

Per SDM, bit 2:0 of CPUID(0x14,1).EAX[2:0] reports the number of
configurable address ranges for filtering, not bit 1:0.
