This patch adds support for performance reporting private feature
for FPGA Management Engine (FME). Now it supports several different
performance counters, including 'basic', 'cache', 'fabric', 'vtd'
and 'vtd_sip'. It allows user to use standard linux tools to access
these performance counters.
e.g. List all events by "perf list"
perf list | grep fme
dfl_fme0/cache_read_hit/ [Kernel PMU event]
dfl_fme0/cache_read_miss/ [Kernel PMU event]
...
dfl_fme0/fab_mmio_read/ [Kernel PMU event]
dfl_fme0/fab_mmio_write/ [Kernel PMU event]
...
dfl_fme0/fab_port_mmio_read,portid=?/ [Kernel PMU event]
dfl_fme0/fab_port_mmio_write,portid=?/ [Kernel PMU event]
...
dfl_fme0/vtd_port_devtlb_1g_fill,portid=?/ [Kernel PMU event]
dfl_fme0/vtd_port_devtlb_2m_fill,portid=?/ [Kernel PMU event]
...
dfl_fme0/vtd_sip_iotlb_1g_hit/ [Kernel PMU event]
dfl_fme0/vtd_sip_iotlb_1g_miss/ [Kernel PMU event]
...
dfl_fme0/clock [Kernel PMU event]
...
e.g. check increased counter value after run one application using
"perf stat" command.
perf stat -e dfl_fme0/fab_mmio_read/,dfl_fme0/fab_mmio_write/ ./test
Performance counter stats for './test':
1 dfl_fme0/fab_mmio_read/
2 dfl_fme0/fab_mmio_write/
1.009496520 seconds time elapsed
Please note that fabric counters support both fab_* and fab_port_*, but
actually they are sharing one set of performance counters in hardware.
If user wants to monitor overall data events on fab_* then fab_port_*
can't be supported at the same time, see example below:
perf stat -e dfl_fme0/fab_mmio_read/,dfl_fme0/fab_port_mmio_write,portid=0/
Performance counter stats for 'system wide':
0 dfl_fme0/fab_mmio_read/
<not supported> dfl_fme0/fab_port_mmio_write,portid=0/

Add sysfs interface to set boot health status from user space.
Add API used by this interface to communicate with firmware.
If PMUFW is compiled with CHECK_HEALTHY_BOOT, it will check the
healthy bit on FPD WDT expiration. If healthy bit is set by a user
application running in Linux, PMUFW will do APU only restart. If
healthy bit is not set during FPD WDT expiration, PMUFW will do
system restart.

The Intel service layer driver has defined error codes for the
specific services, which started from FPGA configuration then RSU
(Remote Status Update).
Intel service layer driver should define the standard error codes
rather than keep adding more error codes for the new services.
The standard error codes will be used by all the clients of Intel service
layer driver.
Replace FPGA and RSU specific error codes with Intel service layer’s
Common error codes.

Pull s390 fixes from Vasily Gorbik:
- Add a few notrace annotations to avoid potential crashes when
switching ftrace tracers.
- Avoid setting affinity for floating irqs in pci code.
- Fix build issue found by kbuild test robot.
* tag 's390-5.7-3' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
s390/protvirt: fix compilation issue
s390/pci: do not set affinity for floating irqs
s390/ftrace: fix potential crashes when switching tracers
- One important fix for a bug in the way we find the cache-line size from the
device tree, which was leading to the wrong size being reported to userspace
on some platforms.
- A fix for 8xx STRICT_KERNEL_RWX which was leaving TLB entries around leading
to a window at boot when the strict mapping wasn't enforced.
- A fix to enable our KUAP (kernel user access prevention) debugging on PPC32.
- A build fix for clang in lib/mpi.

Pull more Devicetree fixes from Rob Herring:
"A couple of schema and kbuild fixes"
* tag 'devicetree-fixes-for-5.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux:

Christoph's patch removed two unsused exported symbols, however, one
symbol is used by the firmware_loader itself. If CONFIG_FW_LOADER=m so
the firmware_loader is modular but CONFIG_FW_LOADER_USER_HELPER=y we fail
the build at mostpost.
ERROR: modpost: "fw_fallback_config" [drivers/base/firmware_loader/firmware_class.ko] undefined!
This happens because the variable fw_fallback_config is built into the
kernel if CONFIG_FW_LOADER_USER_HELPER=y always, so we need to grant
access to the firmware loader module by exporting it.
Revert only one hunk from his patch.
