Subject: staging: octeon: Add a workaround for the issue of GCC8
Date: Wed, 20 Jun 2018 18:41:55 +0800
In function cvm_oct_xmit(), the packet length is set with code like
this:
pko_command.s.total_bytes = skb->len;
But when building with gcc8, the pko_command.s.total_bytes doesn't
emit the right value when it is used in the following codes:
/* Send the packet to the output queue */
if (unlikely(cvmx_pko_send_packet_finish(priv->port,
priv->queue + qos,
pko_command, hw_buffer,
CVMX_PKO_LOCK_NONE))) {
Adding a barrier after the assignment would generate the right codes.

Subject: MIPS: Use '+=" instead of '=' to avoid the CFLAGS override
Date: Mon, 11 Jun 2018 18:17:54 +0800
We used the CFLAGS_xxx to workaround the gcc 8 build warnings
for some specific file. But CFLAGS_xxx is also used with '=' in
other places of this Makefile. This override the gcc 8 workaround,
so replace all the '=' with '+=" to fix this issue.

Add Ethernet TEAM drivers for supporting libteam:
The Team softdev Linux driver provides a mechanism to team multiple
NICs (ports) into a single logical one (teamdev) at L2 layer.
This process is called "channel bonding", "Ethernet bonding", "channel
teaming", "link aggregation", etc. Bonding is already implemented in the
Linux kernel but the Team softdev Linux driver is modular, userspace
driven, very lean and efficient, and it does have some distinct
advantages over the kernel's bonding driver.
Detail description can be found in: http://libteam.org

Subject: modpost: srcversion sometimes incorrect
Date: Fri, 30 Mar 2018 10:14:05 -0700
"srcversion" field inserted into module modinfo section contains a
sum of the source files which made it. However, this field can
be incorrect. Building the same module can end up having inconsistent
srcversion field eventhough the sources remain the same.
This can be reproduced by building modules in a deeply nested directory,
but other factors contribute as well.
The reason for incorrect srcversion is that some source files can be
simply silently skipped from the checksum calculation due to limited
buffer space for line parsing.
This patch addresses two issues:
1. Allocates a larger line buffer (32k vs 4k).
2. Issues a warning if a line length exceeds the line buffer.

This change adds WiFi driver configuration fragments. The fragments are
split into vendor and interface files to allow for easy selection of
drivers for specific interface types (USB, PCI, SDIO) which is useful
for BSPs with specific interfaces. The specific vendor/interface config
fragments can be included by specific BSPs in its .scc files.
However .scc files (wifi-*.scc) are provided to allow enabling interface
specific or all interfaces drivers via KERNEL_FEATURES or inclusion via
other .scc files. And wifi-common.scc is provided to enable the base
config options required for all WiFi drivers, which is done to ensure
correct configuration for default no config setups (e.g.
linux-yocto-tiny).
This patch only enables a limited set of drivers, which is based on what
the common-pc-wifi.cfg fragment sets as well as some additional drivers,
that primarily appear in USB WiFi devices.

The Malta board can support up to 2GiB of RAM which should
be able to boot a Linux kernel built with CONFIG_HIGHMEM

CONFIG_TIMER_STATS has been removed since kernel 4.11.
As per upstream commit:
commit dfb4357da6ddbdf57d583ba64361c9d792b0e0b1
Author: Kees Cook <keescook@chromium.org>
Date: Wed Feb 8 11:26:59 2017 -0800
time: Remove CONFIG_TIMER_STATS
Currently CONFIG_TIMER_STATS exposes process information across namespaces:
kernel/time/timer_list.c print_timer():
SEQ_printf(m, ", %s/%d", tmp, timer->start_pid);
/proc/timer_list:
#11: <0000000000000000>, hrtimer_wakeup, S:01, do_nanosleep, cron/2570
Given that the tracer can give the same information, this patch entirely
removes CONFIG_TIMER_STATS.

Subject: EDAC, pnd2: Conditionally unhide/hide the P2SB PCI device to read BAR
Date: Tue, 19 Sep 2017 03:22:15 -0400
commit 5fd77cb3bac77f690d1d9cf57dc7851fcb3e7945 upstream.
On Deverton server, the P2SB PCI device (DEV:1F, FUN:1) is used by multiple
device drivers.
If it's hidden by some device driver (e.g. with the i801 I2C driver,
the commit
9424693035a5 ("i2c: i801: Create iTCO device on newer Intel PCHs")
unconditionally hid the P2SB PCI device wrongly) it will make the
pnd2_edac driver read out an invalid BAR value of 0xffffffff and then
fail on ioremap().
Therefore, store the presence state of P2SB PCI device before unhiding
it for reading BAR and restore the presence state after reading BAR.

commit bfd4473b850c8cfaa1cdf56b8ef52fae4e8a6ee5 upstream.
Sun, Yunying reported the following failure on Denverton micro-server:
EDAC DEBUG: pnd2_init:

EDAC pnd2: Failed to register device with error -19.
On Denverton micro-server, the presence of the P2SB bridge PCI device is
enabled or disabled by the item 'RelaxSecConf' in BIOS setup menu. When
'RelaxSecConf' is enabled, the P2SB PCI device is present and the pnd2_edac
EDAC driver also uses it to get BAR. Hiding the P2SB PCI device caused the
pnd2_edac EDAC driver failed to get BAR then reported the above failure.
Therefor, store the presence state of P2SB PCI device before unhiding it
for reading BAR and restore the presence state after reading BAR.

Adds dependencies that were missing. In some BSPs, they were satisfied,
in others they weren't and caused warnings.
