2022-10-03mm: hugetlb: eliminate memory-less nodes handlingMuchun Song1-2/+6
The memory-notify-based approach aims to handle meory-less nodes, however, it just adds the complexity of code as pointed by David in thread [1]. The handling of memory-less nodes is introduced by commit 4faf8d950ec4 ("hugetlb: handle memory hot-plug events"). >From its commit message, we cannot find any necessity of handling this case. So, we can simply register/unregister sysfs entries in register_node/unregister_node to simlify the code. BTW, hotplug callback added because in hugetlb_register_all_nodes() we register sysfs nodes only for N_MEMORY nodes, seeing commit 9b5e5d0fdc91, which said it was a preparation for handling memory-less nodes via memory hotplug. Since we want to remove memory hotplug, so make sure we only register per-node sysfs for online (N_ONLINE) nodes in hugetlb_register_all_nodes(). https://lore.kernel.org/linux-mm/60933ffc-b850-976c-78a0-0ee6e0ea9ef0@redhat.com/ [1] Link: https://lkml.kernel.org/r/20220914072603.60293-3-songmuchun@bytedance.com Suggested-by: David Hildenbrand <david@redhat.com> Signed-off-by: Muchun Song <songmuchun@bytedance.com> Acked-by: David Hildenbrand <david@redhat.com> Cc: Andi Kleen <andi@firstfloor.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Mike Kravetz <mike.kravetz@oracle.com> Cc: Oscar Salvador <osalvador@suse.de> Cc: Rafael J.

2022-10-03mm: hugetlb: simplify per-node sysfs creation and removalMuchun Song1-136/+3
Patch series "simplify handling of per-node sysfs creation and removal", v4. This patch (of 2): The following commit offload per-node sysfs creation and removal to a kworker and did not say why it is needed. And it also said "I don't know that this is absolutely required". It seems like the author was not sure as well. Since it only complicates the code, this patch will revert the changes to simplify the code. 39da08cb074c ("hugetlb: offload per node attribute registrations") We could use memory hotplug notifier to do per-node sysfs creation and removal instead of inserting those operations to node registration and unregistration. Then, it can reduce the code coupling between node.c and hugetlb.c. Also, it can simplify the code.

zram_table_entry::flags stores object size in the lower bits and zram pageflags in the upper bits. However, for some reason, we use 24 lower bits, while maximum zram object size is PAGE_SIZE, which requires PAGE_SHIFT bits (up to 16 on arm64). This wastes 24 - PAGE_SHIFT bits that we can use for additional zram pageflags instead. Also add a BUILD_BUG_ON() to alert us should we run out of bits in zram_table_entry::flags.

2022-09-26mm: start tracking VMAs with maple treeLiam R. Howlett1-0/+1
Start tracking the VMAs with the new maple tree structure in parallel with the rb_tree. Add debug and trace events for maple tree operations and duplicate the rb_tree that is created on forks into the maple tree. The maple tree is added to the mm_struct including the mm_init struct, added support in required mm/mmap functions, added tracking in kernel/fork for process forking, and used to find the unmapped_area and checked against what the rbtree finds. This also moves the mmap_lock() in exit_mmap() since the oom reaper call does walk the VMAs. Otherwise lockdep will be unhappy if oom happens. When splitting a vma fails due to allocations of the maple tree nodes, the error path in __split_vma() calls new->vm_ops->close(new). The page accounting for hugetlb is actually in the close() operation, so it accounts for the removal of 1/2 of the VMA which was not adjusted. This results in a negative exit value. To avoid the negative charge, set vm_start = vm_end and vm_pgoff = 0. There is also a potential accounting issue in special mappings from insert_vm_struct() failing to allocate, so reverse the charge there in the failure scenario.

MEMTIER_DEFAULT_DAX_ADISTANCE By default, all nodes are assigned to the default memory tier which is the memory tier designated for nodes with DRAM Set dax kmem device node's tier to slower memory tier by assigning abstract distance to MEMTIER_DEFAULT_DAX_ADISTANCE. Low-level drivers like papr_scm or ACPI NFIT can initialize memory device type to a more accurate value based on device tree details or HMAT. If the kernel doesn't find the memory type initialized, a default slower memory type is assigned by the kmem driver.

2022-08-26fbdev: fbcon: Properly revert changes when vc_resize() failedShigeru Yoshida1-2/+25
fbcon_do_set_font() calls vc_resize() when font size is changed. However, if if vc_resize() failed, current implementation doesn't revert changes for font size, and this causes inconsistent state. syzbot reported unable to handle page fault due to this issue [1]. syzbot's repro uses fault injection which cause failure for memory allocation, so vc_resize() failed. This patch fixes this issue by properly revert changes for font related date when vc_resize() failed.

This is a follow-up to the discussion in [0]. It seems to me that at least the IP version used on Amlogic SoC's sometimes has a problem if register MAC_CTRL_REG is written whilst the chip is still processing a previous write. But that's just a guess. Adding a delay between two writes to this register helps, but we can also simply omit the offending second write. This patch uses the second approach and is based on a suggestion from Qi Duan. Benefit of this approach is that we can save few register writes, also on not affected chip versions.

There is a case found in heavy testing where a link flap happens just before a firmware Recovery event and the driver gets stuck in the BROKEN state. This comes from the driver getting interrupted by a FW generation change when coming back up from the link flap, and the call to ionic_start_queues() in ionic_link_status_check() fails. This can be addressed by having the fw_up code clear the BROKEN bit if seen, rather than waiting for a user to manually force the interface down and then back up.
