[PATCH V4 08/10] MIPS: Loongson-3: Fix CPU UART irq delivery problem

by Huacai Chen

Masking/unmasking the CPU UART irq in CP0_Status (and redirecting it to other CPUs) may cause interrupts be lost, especially in multi-package machines (Package-0's UART irq cannot be delivered to others). So make mask_loongson_irq() and unmask_loongson_irq() be no-ops. The original problem (UART IRQ may deliver to any core) is also because of masking/unmasking the CPU UART irq in CP0_Status. So it is safe to remove all of the stuff.

[PATCH V4 05/10] MIPS: Align kernel load address to 64KB

by Huacai Chen

KEXEC needs the new kernel's load address to be aligned on a page boundary (see sanity_check_segment_list()), but on MIPS the default vmlinuz load address is only explicitly aligned to 16 bytes. Since the largest PAGE_SIZE supported by MIPS kernels is 64KB, increase the alignment calculated by calc_vmlinuz_load_addr to 64KB.

[PATCH v6 1/2] mm: migration: fix migration of huge PMD shared pages

by Mike Kravetz

The page migration code employs try_to_unmap() to try and unmap the source page. This is accomplished by using rmap_walk to find all vmas where the page is mapped. This search stops when page mapcount is zero. For shared PMD huge pages, the page map count is always 1 no matter the number of mappings. Shared mappings are tracked via the reference count of the PMD page. Therefore, try_to_unmap stops prematurely and does not completely unmap all mappings of the source page. This problem can result is data corruption as writes to the original source page can happen after contents of the page are copied to the target page. Hence, data is lost. This problem was originally seen as DB corruption of shared global areas after a huge page was soft offlined due to ECC memory errors. DB developers noticed they could reproduce the issue by (hotplug) offlining memory used to back huge pages. A simple testcase can reproduce the problem by creating a shared PMD mapping (note that this must be at least PUD_SIZE in size and PUD_SIZE aligned (1GB on x86)), and using migrate_pages() to migrate process pages between nodes while continually writing to the huge pages being migrated. To fix, have the try_to_unmap_one routine check for huge PMD sharing by calling huge_pmd_unshare for hugetlbfs huge pages. If it is a shared mapping it will be 'unshared' which removes the page table entry and drops the reference on the PMD page. After this, flush caches and TLB. mmu notifiers are called before locking page tables, but we can not be sure of PMD sharing until page tables are locked. Therefore, check for the possibility of PMD sharing before locking so that notifiers can prepare for the worst possible case.

[PATCH v2 4/9] mmc: meson-mx-sdio: fix OF child-node lookup

by Johan Hovold

Use the new of_get_compatible_child() helper to lookup the slot child node instead of using of_find_compatible_node(), which searches the entire tree from a given start node and thus can return an unrelated (i.e. non-child) node. This also addresses a potential use-after-free (e.g. after probe deferral) as the tree-wide helper drops a reference to its first argument (i.e. the node of the device being probed). While at it, also fix up the related slot-node reference leak.
