Subject: [PATCH 1/8] x86/platform/uv: Save OEM_ID from ACPI MADT probe
Date: Tue, 10 Sep 2019 09:58:40 -0500 [thread overview]
Message-ID: <20190910145839.732237241@stormcage.eag.rdlabs.hpecorp.net> (raw)

[-- Attachment #1: save-oem_id --]
[-- Type: text/plain, Size: 1776 bytes --]
Save the OEM_ID and OEM_TABLE_ID passed to the apic driver probe function
for later use. Also, convert the char list arg passed from the kernel
to a true null-terminated string.
