As mentioned in "Assumption:", current grep expression can't catch font files whose names are changed from upstream "Noto CJK fonts". To avoid false negatives, use command of the form: fc-list : file family variable , where ":" works as a wildcard pattern. Variable fonts can be detected by filtering the output with "variable=True" and "Noto CJK" font-family variants. Signed-off-by:Akira Yokosawa <akiyks@gmail.com> Signed-off-by:

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 the 'code-block:: none' labels and switch to the shorter '::' to reduce noise. 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. Rendered html output looks like before, except for the different level of indentation. CC: Jonathan Corbet <corbet@lwn.net> Signed-off-by:

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 1e596d5e ("docs: Detect variable fonts and suggest denylisting them") adds the new script check-variable-fonts.sh and intends to refer to it in the DOCUMENTATION section in MAINTAINERS. However, the file entry refers to scripts/check-variable-font.sh. Note the missing "s". Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a broken reference. Repair this new file entry in the DOCUMENTATION section. Signed-off-by:

Commit 83919535 ("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. Therefore, let the documentation reflect that the only way to enable the shuffle page allocator is by setting `page_alloc.shuffle=1`. Signed-off-by:

sched_core_share_pid() copies the cookie to userspace with put_user(id, (u64 __user *)uaddr), expecting 64 bits of space. The "unsigned long" datatype that is documented in core-scheduling.rst however is only 32 bits large on 32 bit architectures. Document "unsigned long long" as the correct data type that is always 64bits large. This matches what the selftest cs_prctl_test.c has been doing all along.

Quoting of the '"no regressions" rule' expression differs between occurrences, sometimes being presented as '"no regressions rule"'. Unify the quoting using the first form which seems semantically correct or is at least used dominantly, albeit marginally. One of the occurrences is obviously missing the 'rule' part -- add it.

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.

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. Signed-off-by:Frank Li <Frank.Li@nxp.com> Reviewed-by:
