Subject: [PULL 37/57] acpi: x86: set enabled when composing _MAT entries
Date: Tue, 5 Oct 2021 12:03:31 -0400 [thread overview]
Message-ID: <20211005155946.513818-38-mst@redhat.com> (raw)
In-Reply-To: <20211005155946.513818-1-mst@redhat.com>
From: Igor Mammedov <imammedo@redhat.com>
Instead of composing disabled _MAT entry and then later on
patching it to enabled for hotpluggbale CPUs in DSDT,
set it to enabled at the time _MAT entry is built.
It will allow to drop usage of packed structures in
following patches when build_madt() is switched to use
build_append_int_noprefix() API.
