This adds a pair of APIs that allows the generic PHY subsystem to provide information on the PHY bus width. The PHY provider driver may use phy_set_bus_width() to set the bus width that the PHY supports. The controller driver may then use phy_get_bus_width() to fetch the PHY bus width in order to properly configure the controller.

Since commit 36bc08cc ("fs/aio: Add support to aio ring pages migration") the aio ring setup code has used a special per-ring backing inode for the page allocations, rather than just using random anonymous pages. However, rather than remembering the pages as it allocated them, it would allocate the pages, insert them into the file mapping (dirty, so that they couldn't be free'd), and then forget about them. And then to look them up again, it would mmap the mapping, and then use "get_user_pages()" to get back an array of the pages we just created. Now, not only is that incredibly inefficient, it also leaked all the pages if the mmap failed (which could happen due to excessive number of mappings, for example). So clean it all up, making it much more straightforward. Also remove some left-overs of the previous (broken) mm_populate() usage that was removed in commit d6c355c7 ("aio: fix race in ring buffer page lookup introduced by page migration support") but left the pointless and now misleading MAP_POPULATE flag around.

The arbitrary restriction on page counts offered by the core migrate_page_move_mapping() code results in rather suspicious looking fiddling with page reference counts in the aio_migratepage() operation. To fix this, make migrate_page_move_mapping() take an extra_count parameter that allows aio to tell the code about its own reference count on the page being migrated. While cleaning up aio_migratepage(), make it validate that the old page being passed in is actually what aio_migratepage() expects to prevent misbehaviour in the case of races.

Commit 1bf49dd4 ("./Makefile: export initial ramdisk compression config option") started setting the INITRD_COMPRESS environment variable depending on which decompression models the kernel had available. That is completely broken. For example, we by default have CONFIG_RD_LZ4 enabled, and are able to decompress such an initrd, but the user tools to *create* such an initrd may not be availble. So trying to tell dracut to generate an lz4-compressed image just because we can decode such an image is completely inappropriate.

由 Johannes Weiner 提交于
Commit 81c0a2bb ("mm: page_alloc: fair zone allocator policy") meant to bring aging fairness among zones in system, but it was overzealous and badly regressed basic workloads on NUMA systems. Due to the way kswapd and page allocator interacts, we still want to make sure that all zones in any given node are used equally for all allocations to maximize memory utilization and prevent thrashing on the highest zone in the node. While the same principle applies to NUMA nodes - memory utilization is obviously improved by spreading allocations throughout all nodes - remote references can be costly and so many workloads prefer locality over memory utilization. The original change assumed that zone_reclaim_mode would be a good enough predictor for that, but it turned out to be as indicative as a coin flip. Revert the NUMA aspect of the fairness until we can find a proper way to make it configurable and agree on a sane default.

Sasha Levin found a NULL pointer dereference that is due to a missing page table lock, which in turn is due to the pmd entry in question being a transparent huge-table entry. The code - introduced in commit 1998cc04 ("mm: make madvise(MADV_WILLNEED) support swap file prefetch") - correctly checks for this situation using pmd_none_or_trans_huge_or_clear_bad(), but it turns out that that function doesn't work correctly. pmd_none_or_trans_huge_or_clear_bad() expected that pmd_bad() would trigger if the transparent hugepage bit was set, but it doesn't do that if pmd_numa() is also set. Note that the NUMA bit only gets set on real NUMA machines, so people trying to reproduce this on most normal development systems would never actually trigger this. Fix it by removing the very subtle (and subtly incorrect) expectation, and instead just checking pmd_trans_huge() explicitly.
