[PATCH] dm: fix copying after src array boundaries

The blammed commit copied to argv the size of the reallocated argv, instead of the size of the old_argv, thus reading and copying from past the old_argv allocated memory.

[PATCH 6.6 0/2] PCI: imx6: Fix i.MX7D controller_id backport regression

by Ryan Matthews

Hello, This fixes an i.Mx 7D SoC PCIe regression caused by a backport mistake. The regression is broken PCIe initialization and for me a boot hang. I don't know how to organize this. I think a revert and redo best captures what's happening. To complicate things, it looks like the redo patch could also be applied to 5.4, 5.10, 5.15, and 6.1. But those versions don't have the original backport commit. Version 6.12 matches master and needs no change. One conflict resolution is needed to apply the redo patch back to versions 6.1 -> 5.15 -> 5.10. One more resolution to apply back to -> 5.4. Patches against those other versions aren't included here. -- Ryan Richard Zhu (1): PCI: imx6: Skip controller_id generation logic for i.MX7D Ryan Matthews (1): Revert "PCI: imx6: Skip controller_id generation logic for i.MX7D" drivers/pci/controller/dwc/pci-imx6.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) base-commit: 814637ca257f4faf57a73fd4e38888cce88b5911 -- 2.47.2

[PATCH stable v6.6] riscv: Pass patch_text() the length in bytes

Carlos reports an earlier patch, c0cd6f557b90 ("mm: page_alloc: fix freelist movement during block conversion"), as the root cause for a regression in worst-case zone->lock+irqoff hold times. Both of these patches modify the page allocator's fallback path to be less greedy in an effort to stave off fragmentation. The flip side of this is that fallbacks are also less productive each time around, which means the fallback search can run much more frequently. Carlos' traces point to rmqueue_bulk() specifically, which tries to refill the percpu cache by allocating a large batch of pages in a loop. It highlights how once the native freelists are exhausted, the fallback code first scans orders top-down for whole blocks to claim, then falls back to a bottom-up search for the smallest buddy to steal. For the next batch page, it goes through the same thing again. This can be made more efficient. Since rmqueue_bulk() holds the zone->lock over the entire batch, the freelists are not subject to outside changes; when the search for a block to claim has already failed, there is no point in trying again for the next page. Modify __rmqueue() to remember the last successful fallback mode, and restart directly from there on the next rmqueue_bulk() iteration.

[PATCH v3 1/3] media: videobuf2: use sgtable-based scatterlist wrappers

by Marek Szyprowski

Use common wrappers operating directly on the struct sg_table objects to fix incorrect use of scatterlists sync calls. dma_sync_sg_for_*() functions have to be called with the number of elements originally passed to dma_map_sg_*() function, not the one returned in sgt->nents.
