The NUMA balancing logic uses an arch-specific PROT_NONE page table flag defined by pte_protnone() or pmd_protnone() to mark PTEs or huge page PMDs respectively as requiring balancing upon a subsequent page fault. User-defined PROT_NONE memory regions which also have this flag set will not normally invoke the NUMA balancing code as do_page_fault() will send a segfault to the process before handle_mm_fault() is even called. However if access_remote_vm() is invoked to access a PROT_NONE region of memory, handle_mm_fault() is called via faultin_page() and __get_user_pages() without any access checks being performed, meaning the NUMA balancing logic is incorrectly invoked on a non-NUMA memory region. A simple means of triggering this problem is to access PROT_NONE mmap'd memory using /proc/self/mem which reliably results in the NUMA handling functions being invoked when CONFIG_NUMA_BALANCING is set. This issue was reported in bugzilla (issue 99101) which includes some simple repro code. There are BUG_ON() checks in do_numa_page() and do_huge_pmd_numa_page() added at commit c0e7cad9 to avoid accidentally provoking strange behaviour by attempting to apply NUMA balancing to pages that are in fact PROT_NONE. The BUG_ON()'s are consistently triggered by the repro. This patch moves the PROT_NONE check into mm/memory.c rather than invoking BUG_ON() as faulting in these pages via faultin_page() is a valid reason for reaching the NUMA check with the PROT_NONE page table flag set and is therefore not always a bug.

The fixes to the radix tree test suite show that the multi-order case is broken. The basic reason is that the radix tree code uses tagged pointers with the "internal" bit in the low bits, and calculating the pointer indices was supposed to mask off those bits. But gcc will notice that we then use the index to re-create the pointer, and will avoid doing the arithmetic and use the tagged pointer directly. This cleans the code up, using the existing is_sibling_entry() helper to validate the sibling pointer range (instead of open-coding it), and using entry_to_node() to mask off the low tag bit from the pointer. And once you do that, you might as well just use the now cleaned-up pointer directly. [ Side note: the multi-order code isn't actually ever used in the kernel right now, and the only reason I didn't just delete all that code is that Kirill Shutemov piped up and said: "Well, my ext4-with-huge-pages patchset[1] uses multi-order entries. It also converts shmem-with-huge-pages and hugetlb to them. I'm okay with converting it to other mechanism, but I need something. (I looked into Konstantin's RFC patchset[2]. It looks okay, but I don't feel myself qualified to review it as I don't know much about radix-tree internals.)"

This patch fixes the possibility of a deadlock when bringing up secondary CPUs. The deadlock occurs because the set_cpu_online() is called before synchronise_count_slave(). This can cause a deadlock if the boot CPU, having scheduled another thread, attempts to send an IPI to the secondary CPU, which it sees has been marked online. The secondary is blocked in synchronise_count_slave() waiting for the boot CPU to enter synchronise_count_master(), but the boot cpu is blocked in smp_call_function_many() waiting for the secondary to respond to it's IPI request. Fix this by marking the CPU online in cpu_callin_map and synchronising counters before declaring the CPU online and calculating the maps for IPIs. Signed-off-by:

You might wonder if the feature got tested at all with that bug in: yes, it did, but for wider testing coverage, Kirill and I had each relied too much on an override which bypasses that condition. - huge tmpfs: fix Committed_AS leak just a run-of-the-mill accounting fix in the same feature. - mm: delete unnecessary and unsafe init_tlb_ubc() is an unrelated fix to 4.3's TLB flush batching in reclaim: the bug would be rare, and none of us will be shamed if this one misses 4.8; but it got such a quick ack from Mel today that I'm inclined to offer it along with the first two" * emailed patches from Hugh Dickins <hughd@google.com>: mm: delete unnecessary and unsafe init_tlb_ubc() huge tmpfs: fix Committed_AS leak shmem: fix tmpfs to handle the huge= option properly
