Subject: [PATCH 0/2] perf: Fujitsu: Add Uncore MAC/PCI PMU driver
This adds two new dynamic PMUs to the Perf Events framework to program
and control the Uncore MAC/PCI PMUs in Fujitsu chips.
These drivers were created with reference to drivers/perf/qcom_l3_pmu.c.
These drivers export formatting and event information to sysfs so they can
be used by the perf user space tools with the syntaxes:
perf stat -e mac_iod0_mac0_ch0/ea-mac/ ls
perf stat -e mac_iod0_mac0_ch0/event=0x80/ ls
perf stat -e pci_iod0_pci0/ea-pci/ ls
perf stat -e pci_iod0_pci0/event=0x80/ ls
FUJITSU-MONAKA Specification URL:

I have a question.
When I run scripts/checkpatch.pl, the following WARNING appears.
> WARNING: Missing or malformed SPDX-License-Identifier tag in line 1

Some of the files under Documentation/admin-guide/perf have an
SPDX-License-Identifier tag and some don't. Is it necessary to
include it in fujitsu_mac_pmu.rst and fujitsu_pci_pmu.rst and?
Best regards.
