Subject: [PATCH 4.4 017/105] x86/PCI: Make broadcom_postcore_init() check acpi_disabled
Date: Fri, 15 Dec 2017 10:44:15 +0100 [thread overview]
Message-ID: <20171215092306.801342684@linuxfoundation.org> (raw)
In-Reply-To: <20171215092305.994559179@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
commit ddec3bdee05b06f1dda20ded003c3e10e4184cab upstream.
acpi_os_get_root_pointer() may return a valid address even if acpi_disabled
is set, but the host bridge information from the ACPI tables is not going
to be used in that case and the Broadcom host bridge initialization should
not be skipped then, So make broadcom_postcore_init() check acpi_disabled
too to avoid this issue.
Fixes: 6361d72b04d1 (x86/PCI: read Broadcom CNB20LE host bridge info before PCI scan)
