2024-05-30dt-bindings: thermal: loongson,ls2k-thermal: Fix incorrect compatible definitionBinbin Zhou1-2/+21
[ Upstream commit c8c4353685778e75e186103411e9d01a4a3f2b90 ] The temperature output register of the Loongson-2K2000 is defined in the chip configuration domain, which is different from the Loongson-2K1000, so it can't be fallbacked. We need to use two groups of registers to describe it: the first group is the high and low temperature threshold setting register; the second group is the temperature output register. It is true that this fix will cause ABI corruption, but it is necessary otherwise the Loongson-2K2000 temperature sensor will not work properly.

2024-05-30cpu: Ignore "mitigations" kernel parameter if CPU_MITIGATIONS=nSean Christopherson1-0/+3
[ Upstream commit ce0abef6a1d540acef85068e0e82bdf1fbeeb0e9 ] Explicitly disallow enabling mitigations at runtime for kernels that were built with CONFIG_CPU_MITIGATIONS=n, as some architectures may omit code entirely if mitigations are disabled at compile time. E.g. on x86, a large pile of Kconfigs are buried behind CPU_MITIGATIONS, and trying to provide sane behavior for retroactively enabling mitigations is extremely difficult, bordering on impossible. E.g. page table isolation and call depth tracking require build-time support, BHI mitigations will still be off without additional kernel parameters, etc. [ bp: Touchups. ] Signed-off-by: Sean Christopherson <seanjc@google.com> Signed-off-by: Borislav Petkov (AMD) <bp@alien8.de> Acked-by: Borislav Petkov (AMD) <bp@alien8.de> Link: https://lore.kernel.org/r/20240420000556.2645001-3-seanjc@google.com Signed-off-by: Sasha Levin <sashal@kernel.org>

sysfs file commit da2a061888883e067e8e649d086df35c92c760a7 upstream. The example usage of DAMOS filter sysfs files, specifically the part of 'matching' file writing for memcg type filter, is wrong.

2024-05-17dt-bindings: net: mediatek: remove wrongly added clocks and SerDesDaniel Golle1-20/+2
[ Upstream commit cc349b0771dccebf0fa9f5e1822ac444aef11448 ] Several clocks as well as both sgmiisys phandles were added by mistake to the Ethernet bindings for MT7988. Also, the total number of clocks didn't match with the actual number of items listed. This happened because the vendor driver which served as a reference uses a high number of syscon phandles to access various parts of the SoC which wasn't acceptable upstream. Hence several parts which have never previously been supported (such SerDes PHY and USXGMII PCS) are going to be implemented by separate drivers. As a result the device tree will look much more sane. Quickly align the bindings with the upcoming reality of the drivers actually adding support for the remaining Ethernet-related features of the MT7988 SoC.

2024-04-03docs: Restore "smart quotes" for quotesAkira Yokosawa1-3/+3
[ Upstream commit fe2562582bffe675721e77e00b3bf5bfa1d7aeab ] Commit eaae75754d81 ("docs: turn off "smart quotes" in the HTML build") disabled conversion of quote marks along with that of dashes. Despite the short summary, the change affects not only HTML build but also other build targets including PDF. However, as "smart quotes" had been enabled for more than half a decade already, quite a few readers of HTML pages are likely expecting conversions of "foo" -> “foo” and 'bar' -> ‘bar’. Furthermore, in LaTeX typesetting convention, it is common to use distinct marks for opening and closing quote marks. To satisfy such readers' expectation, restore conversion of quotes only by setting smartquotes_action [1].

2024-04-03media: mc: Expand MUST_CONNECT flag to always require an enabled linkLaurent Pinchart1-6/+5
[ Upstream commit b3decc5ce7d778224d266423b542326ad469cb5f ] The MEDIA_PAD_FL_MUST_CONNECT flag indicates that the pad requires an enabled link to stream, but only if it has any link at all. This makes little sense, as if a pad is part of a pipeline, there are very few use cases for an active link to be mandatory only if links exist at all. A review of in-tree drivers confirms they all need an enabled link for pads marked with the MEDIA_PAD_FL_MUST_CONNECT flag. Expand the scope of the flag by rejecting pads that have no links at all. This requires modifying the pipeline build code to add those pads to the pipeline.

2024-03-15x86/rfds: Mitigate Register File Data Sampling (RFDS)Pawan Gupta2-0/+22
commit 8076fcde016c9c0e0660543e67bff86cb48a7c9c upstream. RFDS is a CPU vulnerability that may allow userspace to infer kernel stale data previously used in floating point registers, vector registers and integer registers. RFDS only affects certain Intel Atom processors. Intel released a microcode update that uses VERW instruction to clear the affected CPU buffers. Unlike MDS, none of the affected cores support SMT. Add RFDS bug infrastructure and enable the VERW based mitigation by default, that clears the affected buffers just before exiting to userspace. Also add sysfs reporting and cmdline parameter "reg_file_data_sampling" to control the mitigation.

2024-03-06dpll: move all dpll<>netdev helpers to dpll codeJakub Kicinski1-1/+1
Older versions of GCC really want to know the full definition of the type involved in rcu_assign_pointer(). struct dpll_pin is defined in a local header, net/core can't reach it. Move all the netdev <> dpll code into dpll, where the type is known. Otherwise we'd need multiple function calls to jump between the compilation units. This is the same problem the commit under fixes was trying to address, but with rcu_assign_pointer() not rcu_dereference(). Some of the exports are not needed, networking core can't be a module, we only need exports for the helpers used by drivers.

2024-02-21docs: translations: use attribute to store current languageVegard Nossum1-6/+4
Akira Yokosawa reported [1] that the "translations" extension we added in commit 7418ec5b151f ("docs: translations: add translations links when they exist") broke the build on Sphinx versions v6.1.3 through 7.1.2 (possibly others) with the following error: Exception occurred: File "/usr/lib/python3.12/site-packages/sphinx/util/nodes.py", line 624, in _copy_except__document newnode = self.__class__(rawsource=self.rawsource, **self.attributes) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ TypeError: LanguagesNode.__init__() missing 1 required positional argument: 'current_language' The full traceback has been saved in /tmp/sphinx-err-7xmwytuu.log, if you want to report the issue to the developers. Solve this problem by making 'current_language' a true element attribute of the LanguagesNode element, which is probably the more correct way to do it anyway. Tested on Sphinx 2.x, 3.x, 6.x, and 7.x.

2024-02-21docs: Instruct LaTeX to cope with deeper nestingJonathan Corbet1-0/+6
The addition of the XFS online fsck documentation starting with commit a8f6c2e54ddc ("xfs: document the motivation for online fsck design") added a deeper level of nesting than LaTeX is prepared to deal with. That caused a pdfdocs build failure with the helpful "Too deeply nested" error message buried deeply in Documentation/output/filesystems.log. Increase the "maxlistdepth" parameter to instruct LaTeX that it needs to deal with the deeper nesting whether it wants to or not.
