+Subject: [PATCH] x86/amd_nb: Add PCI device IDs for family 17h, model 70h
+
+The AMD Ryzen gen 3 processors came with a different PCI IDs for the
+function 3 & 4 which are used to access the SMN interface. The root
+PCI address however remained at the same address as the model 30h.
+
+Adding the F3/F4 PCI IDs respectively to the misc and link ids appear
+to be sufficient for k10temp, so let's add them and follow up on the
+patch if other functions need more tweaking.
+
+Vicki Pfau sent an identical patch after I checked that no-one had
+written this patch. I would have been happy about dropping my patch but
+unlike for his patch series, I had already Cc:ed the x86 people and
+they already reviewed the changes. Since Vicki has not answered to
+any email after his initial series, let's assume she is on vacation
+and let's avoid duplication of reviews from the maintainers and merge
+my series. To acknowledge Vicki's anteriority, I added her S-o-b to
+the patch.
+
+v2, suggested by Guenter Roeck and Brian Woods:
+ - rename from 71h to 70h

+Subject: [PATCH] ACPI / irq: Workaround firmware issue on X-Gene based
+ m400
+
+The ACPI firmware on the xgene-based m400 platorms erroneously
+describes its UART interrupt as ACPI_PRODUCER rather than
+ACPI_CONSUMER. This leads to the UART driver being unable to
+find its interrupt and the kernel unable find a console.
+Work around this by avoiding the producer/consumer check
+for X-Gene UARTs.

+Subject: [PATCH] Input - synaptics: pin 3 touches when the firmware reports 3
+ fingers
+
+Synaptics PS/2 touchpad can send only 2 touches in a report. They can
+detect 4 or 5 and this information is valuable.
+
+In commit 63c4fda (Input: synaptics - allocate 3 slots to keep stability
+in image sensors), we allocate 3 slots, but we still continue to report
+the 2 available fingers. That means that the client sees 2 used slots while
+there is a total of 3 fingers advertised by BTN_TOOL_TRIPLETAP.
+
+For old kernels this is not a problem because max_slots was 2 and libinput/
+xorg-synaptics knew how to deal with that. Now that max_slot is 3, the
+clients ignore BTN_TOOL_TRIPLETAP and count the actual used slots (so 2).
+It then gets confused when receiving the BTN_TOOL_TRIPLETAP and DOUBLETAP
+information, and goes wild.
+
+We can pin the 3 slots until we get a total number of fingers below 2.

+From: Josh Stone <jistone@redhat.com>

+Subject: [PATCH] Kbuild: Add an option to enable GCC VTA
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Due to recent codegen issues, gcc -fvar-tracking-assignments was
+unconditionally disabled in commit 2062afb4f804a ("Fix gcc-4.9.0
+miscompilation of load_balance() in scheduler").  However, this reduces
+the debuginfo coverage for variable locations, especially in inline
+functions.  VTA is certainly not perfect either in those cases, but it
+is much better than without.  With compiler versions that have fixed the
+codegen bugs, we would prefer to have the better details for SystemTap,
+and surely other debuginfo consumers like perf will benefit as well.
+
+This patch simply makes CONFIG_DEBUG_INFO_VTA an option.  I considered
+Frank and Linus's discussion of a cc-option-like -fcompare-debug test,
+but I'm convinced that a narrow test of an arch-specific codegen issue
+is not really useful.  GCC has their own regression tests for this, so
+I'd suggest GCC_COMPARE_DEBUG=-fvar-tracking-assignments-toggle is more
+useful for kernel developers to test confidence.
+
+In fact, I ran into a couple more issues when testing for this patch[1],
+although neither of those had any codegen impact.
+ [1] https://bugzilla.redhat.com/show_bug.cgi?id=1140872
+
+With gcc-4.9.2-1.fc22, I can now build v3.18-rc5 with Fedora's i686 and
+x86_64 configs, and this is completely clean with GCC_COMPARE_DEBUG.

-The Kernel dist-git
-===================
-
-The kernel is maintained in a `source tree`_ rather than directly in dist-git.
-The specfile is maintained as a `template`_ in the source tree along with a set
-of build scripts to generate configurations, (S)RPMs, and to populate the
-dist-git repository.
-
-The `documentation`_ for the source tree covers how to contribute and maintain
-the tree.
-
-If you're looking for the downstream patch set it's available in the source
-tree with "git log master..ark-patches" or
-`online`_.
-
-Each release in dist-git is tagged in the source repository so you can easily
-check out the source tree for a build. The tags are in the format
-name-version-release, but note release doesn't contain the dist tag since the
-source can be built in different build roots (Fedora, CentOS, etc.)

+
+		Kernel package tips & tricks.
+		~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The kernel is one of the more complicated packages in the distro, and
+for the newcomer, some of the voodoo in the spec file can be somewhat scary.
+This file attempts to document some of the magic.
+
+
+Speeding up make prep
+---------------------
+The kernel is nearly 500MB of source code, and as such, 'make prep'
+takes a while. The spec file employs some trickery so that repeated
+invocations of make prep don't take as long.  Ordinarily the %prep
+phase of a package will delete the tree it is about to untar/patch.
+The kernel %prep keeps around an unpatched version of the tree,
+and makes a symlink tree clone of that clean tree and than applies
+the patches listed in the spec to the symlink tree.
+This makes a huge difference if you're doing multiple make preps a day.
+As an added bonus, doing a diff between the clean tree and the symlink
+tree is slightly faster than it would be doing two proper copies of the tree.
+
+
+Build logs.
+-----------
+There's a convenience helper script in scripts/grab-logs.sh
+that will grab the build logs from koji for the kernel version reported
+by make verrel
+
+
+Config hierarchy.
+-----------------
+Instead of having to maintain a config file for every arch variant we build on,
+the kernel spec uses a nested system of configs. Each option CONFIG_FOO is
+represented by a single file named CONFIG_FOO which contains the state (=y, =m,
+=n). These options are collected in the folder base-generic. Architecture
+specific options are set in nested folders. An option set in a nested folder
+will override the same option set in one of the higher levels.
+
+The individual CONFIG_FOO files only exist in the pkg-git repository. The RPM
+contains kernel-foo.config files which are the result of combining all the
+CONFIG_FOO files. The files are combined by running build_configs.sh. This
+script _must_ be run each time one of the options is changed.
+
+Example flow:
+
+# Enable the option CONFIG_ABC123 as a module for all arches
+echo "CONFIG_ABC123=m" > configs/base-generic/CONFIG_ABC1234
+# enable the option CONFIG_XYZ321 for only x86
+echo "# CONFIG_XYZ321 is not set" > configs/base-generic/CONFIG_XYZ321
+echo "CONFIG_XYZ321=m" > configs/base-generic/x86/CONFIG_XYZ321
+# regenerate the combined config files
+./build_configs.sh
+
+The file config_generation gives a listing of what folders go into each
+config file generated.
+
+Debug options.
+--------------
+This is a little complicated, as the purpose & meaning of this changes
+depending on where we are in the release cycle.
+If we are building for a current stable release, 'make release' has
+typically been run already, which sets up the following..
+- Two builds occur, a 'kernel' and a 'kernel-debug' flavor.
+- kernel-debug will get various heavyweight debugging options like
+  lockdep etc turned on.
+
+If we are building for rawhide, 'make debug' has been run, which changes
+the status quo to:
+- We only build one kernel 'kernel'
+- The debug options are always turned on.
+This is done to increase coverage testing, as not many people actually
+run kernel-debug.
+
+The debug options are managed in a separate heierarchy under base-debug. This
+works in a similar manner to base-generic. More deeply nested folders, again,
+override options. The file config_generation gives a listing of what folders
+go into each config file generated.

+From: Bjorn Andersson <bjorn.andersson@linaro.org>
+
+The Lenovo Yoga C630 is built on the SDM850 from Qualcomm, but this seem
+to be similar enough to the SDM845 that we can reuse the sdm845.dtsi.
+
+Supported by this patch is: keyboard, battery monitoring, UFS storage,
+USB host and Bluetooth.

+Date: Thu,  5 Sep 2019 20:24:12 +0100

+
+We have a production-level laptop (Lenovo Yoga C630) which is exhibiting
+a rather horrific bug.  When I2C HID devices are being scanned for at
+boot-time the QCom Geni based I2C (Serial Engine) attempts to use DMA.
+When it does, the laptop reboots and the user never sees the OS.
+
+Attempts are being made to debug the reason for the spontaneous reboot.
+No luck so far, hence the requirement for this hot-fix.  This workaround
+will be removed once we have a viable fix.
