| debian/dfsg/video-remove-nvidiafb-and-rivafb.patch | video: Remove nvidiafb and rivafb These drivers contain register programming code provided by the hardware vendor that appears to have been deliberately obfuscated. This is arguably not the preferred form for modification. These drivers are also largely redundant with nouveau. The RIVA 128 (NV3) is not supported by nouveau but is about 15 years old and probably discontinued 10 years ago. |

| debian/kernelvariables.patch | kbuild: Make the toolchain variables easily overwritable Allow make variables to be overridden for each flavour by a file in the build tree, .kernelvariables. We currently use this for ARCH, KERNELRELEASE, CC, and in some cases also CROSS_COMPILE, KCFLAGS. This file can only be read after we establish the build tree, and all use of $(ARCH) needs to be moved after this. [bwh: Updated for 5.3: include .kernelvariables from current directory rather than using undefined $(obj).] |

| debian/ia64-hardcode-arch-script-output.patch | Hardcode arch script output Here's a patch that simply uses hardcoded definitions instead of doing the dynamic tests that require architecture-specific scripts. I don't particularly like this approach because it restricts portability and diverts from upstream. But, it is simpler, and this really needs to be fixed somehow before etch (along with a rebuild of linux-modules-extra-2.6), so I'm willing to live with it if my other patch is deemed unacceptable. My primary concern is that, in the future, the output of these scripts will change and we (or our successors) will either not notice or forget to update the hardcoded values. Including the scripts in linux-kbuild will avoid this manual step altogether, and allow for the possibility of other archs to provide their own scripts in the future. |

Secondary commit message: "The mainline replacement for ashmem is memfd, so remove the legacy code from drivers/staging/" Consequently, the ashmem part of this patch has been removed. |

| debian/kbuild-look-for-module.lds-under-arch-directory-too.patch | kbuild: Look for module.lds under arch directory too The module.lds linker script is now built under the scripts directory, where previously it was under arch/$(SRCARCH). However, we package the scripts directory as linux-kbuild, which is meant to be able to do support native and cross-builds. That means it shouldn't contain files for a specific target architecture without a wrapper to select between them, and it doesn't appear that linker scripts are powerful enough to implement such a wrapper. Building module.lds in a different location would require relatively large changes. Moving it in the package build rules can work, but we need to support custom kernel builds from the same source so we can't assume it's moved. Therefore, we move module.lds under the arch build directory in rules.real and change Makefile.modfinal to look for it in both places. |

| debian/kbuild-abort-build-if-subdirs-used.patch | kbuild: Abort build if SUBDIRS used DKMS and module-assistant both build OOT modules as root. If they build an old OOT module that still use SUBDIRS this causes Kbuild to try building a full kernel, which obviously fails but not before deleting files from the installed headers package. To avoid such mishaps, detect this situation and abort the build. The error message is based on that used in commit 0126be38d988 "kbuild: announce removal of SUBDIRS if used". |

| debian/module-avoid-abi-changes-when-debug-info-is-disabled.patch | module: Avoid ABI changes when debug info is disabled CI builds are done with debug info disabled, but this removes some members from struct module.

| debian/makefile-make-compiler-version-comparison-optional.patch | Makefile: Make compiler version comparison optional The top-level Makefile warns if the compiler version string changes at all between the kernel build and an out-of-tree module build. We expect that major compiler version changes could introduce ABI changes, and override the CC variable in out-of-tree module builds to ensure that the same major compiler version is used. But minor version changes should not make a difference, so this exact version comparison produces false warnings. Since custom kernel packages don't have that, don't remove the version comparison. Instead, skip it if $(DEBIAN_KERNEL_NO_CC_VERSION_CHECK) is non-empty. |

| debian/iwlwifi-do-not-request-unreleased-firmware.patch | iwlwifi: Do not request unreleased firmware for IWL6000 The iwlwifi driver currently supports firmware API versions 4-6 for these devices. It will request the file for the latest supported version and then fall back to earlier versions. However, the latest version that has actually been released is 4, so we expect the requests for versions 6 and then 5 to fail. The installer appears to report any failed request, and it is probably not easy to detect that this particular failure is harmless. So stop requesting the unreleased firmware. |

| bugfix/all/firmware_class-log-every-success-and-failure.patch | firmware_class: Log every success and failure against given device The hundreds of users of request_firmware() have nearly as many different log formats for reporting failures. They also have only the vaguest hint as to what went wrong; only firmware_class really knows that. Therefore, add specific log messages for the failure modes that aren't currently logged. In case of a driver that tries multiple names, this may result in the impression that it failed to initialise. Therefore, also log successes. This makes many error messages in drivers redundant, which will be removed in later patches. This does not cover the case where we fall back to a user-mode helper (which is no longer enabled in Debian). format to detect missing firmware. |

| bugfix/all/radeon-amdgpu-firmware-is-required-for-drm-and-kms-on-r600-onward.patch | radeon, amdgpu: Firmware is required for DRM and KMS on R600 onward radeon requires firmware/microcode for the GPU in all chips, but for newer chips (apparently R600 'Evergreen' onward) it also expects firmware for the memory controller and other sub-blocks. radeon attempts to gracefully fall back and disable some features if the firmware is not available, but becomes unstable - the framebuffer and/or system memory may be corrupted, or the display may stay black. Therefore, perform a basic check for the existence of /lib/firmware/{radeon,amdgpu} when a device is probed, and abort if it is missing, except for the pre-R600 case. |

This will explain why some firmware is in non-free, or can't be packaged at all. Only do this once per boot. Do something similar in the radeon and amdgpu drivers, where we have an early check to avoid failing at a point where we cannot display anything. |

When removing the driver, ieee802111_unregister_hw is called unconditionally leading to a kernel NULL pointer dereference. Fix the issue running mt76_unregister_device routine just for registered hw.

| features/arm/arm-dts-bcm-Enable-device-tree-overlay-support-for-R.patch | [PATCH] arm: dts: bcm: Enable device-tree overlay support for RPi devices Add the '-@' DTC option for the Raspberry Pi devices. This option populates the '__symbols__' node that contains all the necessary symbols for supporting device-tree overlays (for instance from the firmware or the bootloader) on these devices. The Rasbperry Pi devices are well known for their GPIO header, that allow various "HATs" or other modules do be connected and this enables users to create out-of-tree device-tree overlays for these modules. Please note that this change does increase the size of the resulting DTB by ~40%. For example, with v6.4-rc1 increase in size is as follows: bcm2711-rpi-400.dtb 27556 -> 38141 bytes bcm2711-rpi-4-b.dtb 27484 -> 38069 bytes bcm2711-rpi-cm4-io.dtb 27373 -> 38076 bytes bcm2835-rpi-a.dtb 12879 -> 18235 bytes bcm2835-rpi-a-plus.dtb 13015 -> 18371 bytes bcm2835-rpi-b.dtb 12997 -> 18377 bytes bcm2835-rpi-b-plus.dtb 13237 -> 18666 bytes bcm2835-rpi-b-rev2.dtb 13085 -> 18514 bytes bcm2835-rpi-cm1-io1.dtb 13109 -> 18528 bytes bcm2835-rpi-zero.dtb 12923 -> 18311 bytes bcm2835-rpi-zero-w.dtb 13449 -> 18889 bytes bcm2836-rpi-2-b.dtb 14500 -> 20252 bytes bcm2837-rpi-3-a-plus.dtb 14930 -> 20713 bytes bcm2837-rpi-3-b.dtb 15107 -> 20979 bytes bcm2837-rpi-3-b-plus.dtb 15463 -> 21443 bytes bcm2837-rpi-cm3-io3.dtb 14429 -> 20098 bytes bcm2837-rpi-zero-2-w.dtb 14781 -> 20524 bytes [ukleinek: rebased to v6.4-rc1] |

We can mitigate the effect of any remaining vulnerabilities in such protocols by preventing unprivileged users from loading the modules, so that they are only exploitable on systems where the administrator has chosen to load the protocol. The 'af_802154' (IEEE 802.15.4) protocol is not widely used, was not present in the 'lenny' kernel, and seems to receive only sporadic maintenance. Therefore disable auto-loading. |

Enabling the IOMMU for all devices causes breakage, but turning it off for all graphics devices seems like a major weakness. Add an option, intel_iommu=intgpu_off, to exclude only integrated GPUs from remapping. This is a narrower exclusion than igfx_off: it only affects Intel devices on the root bus.

On PCs where no sound is wanted at all, both drivers will still be loaded and one or other will complain that it couldn't claim the relevant I/O range.

Currently, it is blacklisted by udev along with most other framebuffer drivers, so this doesn't matter much. However, this driver is required for console support on the XO 1.5.

The ODROID M1 has 2 type A USB 3.0 connectors, with the USB 3.0 signals connected to the two combo PHYs. For the USB 2.0 signals, one connector is connected to the host-only PHY and uses the same power switch as the USB 2.0 ports. The other connector has its own power switch and is connected to the OTG PHY, which is also connected to a device only micro-USB connector. The purpose of this micro-USB connector is for firmware update using the Rockusb vendor specific USB class. Therefore it does not make sense to enable this port on Linux, and the PHY is forced to host mode. |

No-one seems interested in regularly checking for vulnerabilities specific to x32 (at least no-one with a white hat). Still, adding another flavour just to turn on x32 seems wasteful. And the only differences on syscall entry are a few instructions that mask out the x32 flag and compare the syscall number. Use a static key to control whether x32 syscalls are really enabled, a Kconfig parameter to set its default value and a kernel parameter "syscall.x32" to change it at boot time. |

So, r/w into this single shared variable by many threads on different CPUs creates a lot caching and memory overhead, hence perf regression. And, it's not accurate due to the high volume concurrent r/w. For example, a workload is iperf with 128 threads, and with RPS enabled. We saw perf regression of 25% with the previous patch adding the counters. And this patch eliminates the regression. Since the error path of mana_poll_rx_cq() already has warnings, so keeping the counter and convert it to a per-queue variable is not necessary. So, just remove this counter from this high frequency code path. Also, remove the tx_cqes counter for the same reason. We have warnings & other counters for errors on that path, and don't need to count every normal cqe processing. (cherry picked from commit 1919b39fc6eabb9a6f9a51706ff6d03865f5df29) |

| features/all/ethernet-microsoft/0027-net-mana-Use-the-correct-WQE-count-for-ringing-RQ-do.patch | [PATCH 27/34] net: mana: Use the correct WQE count for ringing RQ doorbell The hardware specification specifies that WQE_COUNT should set to 0 for the Receive Queue. Although currently the hardware doesn't enforce the check, in the future releases it may check on this value. (cherry picked from commit f5e39b57124fd4715d7f0e2f841b8609b38f3e40) |

This patch sets the hwc timeout from the hardware. It now uses a new hardware capability GDMA_DRV_CAP_FLAG_1_HWC_TIMEOUT_RECONFIG to query and set the value in hwc_timeout.
