2024-05-02docs: stable-kernel-rules: create special tag to flag 'no backporting'Thorsten Leemhuis1-0/+6
Document a new variant of the stable tag developers can use to make the stable team's tools ignore a change[1]. That way developers can use 'Fixes:' tags without fearing the changes might be backported in semi-automatic fashion. Such concerns are the reason why some developers deliberately omit the 'Fixes:' tag in changes[2] -- which somewhat undermines the reason for the existence of that tag and might be unwise in the long term[3].

Remove a unneeded level of indentation, as that reduces the chance that readers have to scroll sideways in some of the code blocks. No text changes.

2024-04-24kernel-doc: fix struct_group_tagged() parsingKees Cook1-1/+2
kernel-doc emits a warning on struct_group_tagged() if you describe your struct group member: include/net/libeth/rx.h:69: warning: Excess struct member 'fp' description in 'libeth_fq' The code: /** * struct libeth_fq - structure representing a buffer queue * @fp: hotpath part of the structure * @pp: &page_pool for buffer management [...] */ struct libeth_fq { struct_group_tagged(libeth_fq_fp, fp, struct page_pool *pp; [...] ); When a struct_group_tagged() is encountered, we need to build a `struct TAG NAME;` from it, so that it will be treated as a valid embedded struct. Decouple the regex and do the replacement there. As far as I can see, this doesn't produce any new warnings on the current mainline tree.

Commit 839195352d82 ("mm/shuffle: remove dynamic reconfiguration") removed the dynamic reconfiguration capabilities from the shuffle page allocator. This means that, now, we don't have any perspective of an "autodetection of memory-side-cache" that triggers the enablement of the shuffle page allocator.

2024-04-10docs: Detect variable fonts and suggest denylisting themAkira Yokosawa4-5/+129
Fedora and openSUSE has started deploying "variable font" [1] format Noto CJK fonts [2, 3]. "CJK" here stands for "Chinese, Japanese, and Korean". Unfortunately, XeTeX/XeLaTeX doesn't understand those fonts for historical reasons and builds of translations.pdf end up in errors if such fonts are present on the build host. To help developers work around the issue, add a script to check the presence of "variable font" Noto CJK fonts and to emit suggestions. The script is invoked in the error path of "make pdfdocs" so that the suggestions are made only when a PDF build actually fails. The first suggestion is to denylist those "variable font" files by activating a per-user and command-local fontconfig setting. For further info and backgrounds, please refer to the header comment of scripts/check-variable-font.sh newly added in this commit.

Extend commit 84b4cc8189f2 ("docs: scripts: sphinx-pre-install: Fix building docs with pyyaml package") and add pyyaml as an optional package to Mageia, ArchLinux, and Gentoo. The Python module pyyaml is required to build the docs, but it is only listed in Documentation/sphinx/requirements.txt and is therefore missing when Sphinx is installed as a package and not via pip/pypi.

2024-04-02docs: dma: correct dma_set_mask() sample codeFrank Li1-2/+22
There are bunch of codes in driver like if (dma_set_mask_and_coherent(dev, DMA_BIT_MASK(64))) dma_set_mask_and_coherent(dev, DMA_BIT_MASK(32)) Actually it is wrong because if dma_set_mask_and_coherent(64) fails, dma_set_mask_and_coherent(32) will fail for the same reason. And dma_set_mask_and_coherent(64) never returns failure. According to the definition of dma_set_mask(), it indicates the width of address that device DMA can access. If it can access 64-bit address, it must access 32-bit address inherently. So only need set biggest address width. See below code fragment: dma_set_mask(mask) { mask = (dma_addr_t)mask; if (!dev->dma_mask || !dma_supported(dev, mask)) return -EIO; arch_dma_set_mask(dev, mask); *dev->dma_mask = mask; return 0; } dma_supported() will call dma_direct_supported or iommux's dma_supported call back function. int dma_direct_supported(struct device *dev, u64 mask) { u64 min_mask = (max_pfn - 1) << PAGE_SHIFT; /* * Because 32-bit DMA masks are so common we expect every architecture * to be able to satisfy them - either by not supporting more physical * memory, or by providing a ZONE_DMA32. If neither is the case, the * architecture needs to use an IOMMU instead of the direct mapping. */ if (mask >= DMA_BIT_MASK(32)) return 1; ... } The iommux's dma_supported() actually means iommu requires devices's minimized dma capability. An example: static int sba_dma_supported( struct device *dev, u64 mask)() { ... * check if mask is >= than the current max IO Virt Address * The max IO Virt address will *always* < 30 bits. */ return((int)(mask >= (ioc->ibase - 1 + (ioc->pdir_size / sizeof(u64) * IOVP_SIZE) ))); ... } 1 means supported. 0 means unsupported. Correct document to make it more clear and provide correct sample code.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fixes from Thomas Gleixner: - Ensure that the encryption mask at boot is properly propagated on 5-level page tables, otherwise the PGD entry is incorrectly set to non-encrypted, which causes system crashes during boot. - Undo the deferred 5-level page table setup as it cannot work with memory encryption enabled. - Prevent inconsistent XFD state on CPU hotplug, where the MSR is reset to the default value but the cached variable is not, so subsequent comparisons might yield the wrong result and as a consequence the result prevents updating the MSR. - Register the local APIC address only once in the MPPARSE enumeration to prevent triggering the related WARN_ONs() in the APIC and topology code. - Handle the case where no APIC is found gracefully by registering a fake APIC in the topology code. That makes all related topology functions work correctly and does not affect the actual APIC driver code at all. - Don't evaluate logical IDs during early boot as the local APIC IDs are not yet enumerated and the invoked function returns an error code. Nothing requires the logical IDs before the final CPUID enumeration takes place, which happens after the enumeration. - Cure the fallout of the per CPU rework on UP which misplaced the copying of boot_cpu_data to per CPU data so that the final update to boot_cpu_data got lost which caused inconsistent state and boot crashes. - Use copy_from_kernel_nofault() in the kprobes setup as there is no guarantee that the address can be safely accessed. - Reorder struct members in struct saved_context to work around another kmemleak false positive - Remove the buggy code which tries to update the E820 kexec table for setup_data as that is never passed to the kexec kernel. - Update the resource control documentation to use the proper units. - Fix a Kconfig warning observed with tinyconfig * tag 'x86-urgent-2024-03-24' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/boot/64: Move 5-level paging global variable assignments back x86/boot/64: Apply encryption mask to 5-level pagetable update x86/cpu: Add model number for another Intel Arrow Lake mobile processor x86/fpu: Keep xfd_state in sync with MSR_IA32_XFD Documentation/x86: Document that resctrl bandwidth control units are MiB x86/mpparse: Register APIC address only once x86/topology: Handle the !APIC case gracefully x86/topology: Don't evaluate logical IDs during early boot x86/cpu: Ensure that CPU info updates are propagated on UP kprobes/x86: Use copy_from_kernel_nofault() to read from unsafe address x86/pm: Work around false positive kmemleak report in msr_build_context() x86/kexec: Do not update E820 kexec table for setup_data x86/config: Fix warning for 'make ARCH=x86_64 tinyconfig'
