This reverts commit aac2fea9. It turns out that that patch was complete and utter garbage, and broke KVM, resulting in odd oopses. Quoting Andrea Arcangeli: "The aforementioned commit has 3 bugs. 1) mmu_notifier_invalidate_range cannot be used in replacement of mmu_notifier_invalidate_range_start/end. For KVM mmu_notifier_invalidate_range is a noop and rightfully so. A MMU notifier implementation has to implement either ->invalidate_range method or the invalidate_range_start/end methods, not both. And if you implement invalidate_range_start/end like KVM is forced to do, calling mmu_notifier_invalidate_range in common code is a noop for KVM. For those MMU notifiers that can get away only implementing ->invalidate_range, the ->invalidate_range is implicitly called by mmu_notifier_invalidate_range_end(). And only those secondary MMUs that share the same pagetable with the primary MMU (like AMD iommuv2) can get away only implementing ->invalidate_range. So all cases (THP on/off) are broken right now. To fix this is enough to replace mmu_notifier_invalidate_range with mmu_notifier_invalidate_range_start;mmu_notifier_invalidate_range_end. Either that or call multiple mmu_notifier_invalidate_page like before. 2) address + (1UL << compound_order(page) is buggy, it should be PAGE_SIZE << compound_order(page), it's bytes not pages, 2M not 512. 3) The whole invalidate_range thing was an attempt to call a single invalidate while walking multiple 4k ptes that maps the same THP (after a pmd virtual split without physical compound page THP split). It's unclear if the rmap_walk will always provide an address that is 2M aligned as parameter to try_to_unmap_one, in presence of THP. I think it needs also an address &= (PAGE_SIZE << compound_order(page)) - 1 to be safe" In general, we should stop making excuses for horrible MMU notifier users. It's much more important that the core VM is sane and safe, than letting MMU notifiers sleep. So if some MMU notifier is sleeping under a spinlock, we need to fix the notifier, not try to make excuses for that garbage in the core VM. Reported-and-tested-by:

The only downside is that we can't support Security Send / Receive for a device with an older revision due to the conflicting use of this field in earlier specifications. tj: The reason we need this is because some devices which don't support READ LOG PAGE lock up after getting issued that command.

Commit 3510ca20 ("Minor page waitqueue cleanups") made the page queue code always add new waiters to the back of the queue, which helps upcoming patches to batch the wakeups for some horrid loads where the wait queues grow to thousands of entries. However, I forgot about the nasrt add_page_wait_queue() special case code that is only used by the cachefiles code. That one still continued to add the new wait queue entries at the beginning of the list. Fix it, because any sane batched wakeup will require that we don't suddenly start getting new entries at the beginning of the list that we already handled in a previous batch. [ The current code always does the whole list while holding the lock, so wait queue ordering doesn't matter for correctness, but even then it's better to add later entries at the end from a fairness standpoint ] Signed-off-by:

When !NUMA, cpumask_of_node(@node) equals cpu_online_mask regardless of @node. The assumption seems that if !NUMA, there shouldn't be more than one node and thus reporting cpu_online_mask regardless of @node is correct. However, that assumption was broken years ago to support DISCONTIGMEM and whether a system has multiple nodes or not is separately controlled by NEED_MULTIPLE_NODES. This means that, on a system with !NUMA && NEED_MULTIPLE_NODES, cpumask_of_node() will report cpu_online_mask for all possible nodes, indicating that the CPUs are associated with multiple nodes which is an impossible configuration. This bug has been around forever but doesn't look like it has caused any noticeable symptoms. However, it triggers a WARN recently added to workqueue to verify NUMA affinity configuration. Fix it by reporting empty cpumask on non-zero nodes if !NUMA. Signed-off-by:

Recent commit a8ec3ee8 "arc: Mask individual IRQ lines during core INTC init" breaks interrupt handling on ARCv2 SMP systems. That commit masked all interrupts at onset, as some controllers on some boards (customer as well as internal), would assert interrutps early before any handlers were installed. For SMP systems, the masking was done at each cpu's core-intc. Later, when the IRQ was actually requested, it was unmasked, but only on the requesting cpu. For "common" interrupts, which were wired up from the 2nd level IDU intc, this was as issue as they needed to be enabled on ALL the cpus (given that IDU IRQs are by default served Round Robin across cpus) So fix that by NOT masking "common" interrupts at core-intc, but instead at the 2nd level IDU intc (latter already being done in idu_of_init()) Fixes: a8ec3ee8 ("arc: Mask individual IRQ lines during core INTC init") Signed-off-by:

Commit 464d6242 ("select: switch compat_{get,put}_fd_set() to compat_{get,put}_bitmap()") changed the calculation on how many bytes need to be zeroed when userspace handed over a NULL pointer for a fdset array in the select syscall. The calculation was changed in compat_get_fd_set() wrongly from memset(fdset, 0, ((nr + 1) & ~1)*sizeof(compat_ulong_t)); to memset(fdset, 0, ALIGN(nr, BITS_PER_LONG)); The ALIGN(nr, BITS_PER_LONG) calculates the number of _bits_ which need to be zeroed in the target fdset array (rounded up to the next full bits for an unsigned long). But the memset() call expects the number of _bytes_ to be zeroed. This leads to clearing more memory than wanted (on the stack area or even at kmalloc()ed memory areas) and to random kernel crashes as we have seen them on the parisc platform. The correct change should have been memset(fdset, 0, (ALIGN(nr, BITS_PER_LONG) / BITS_PER_LONG) * BYTES_PER_LONG); which is the same as can be archieved with a call to zero_fd_set(nr, fdset).

The "lock_page_killable()" function waits for exclusive access to the page lock bit using the WQ_FLAG_EXCLUSIVE bit in the waitqueue entry set. That means that if it gets woken up, other waiters may have been skipped. That, in turn, means that if it sees the page being unlocked, it *must* take that lock and return success, even if a lethal signal is also pending. So instead of checking for lethal signals first, we need to check for them after we've checked the actual bit that we were waiting for. Even if that might then delay the killing of the process. This matches the order of the old "wait_on_bit_lock()" infrastructure that the page locking used to use (and is still used in a few other areas). Note that if we still return an error after having unsuccessfully tried to acquire the page lock, that is ok: that means that some other thread was able to get ahead of us and lock the page, and when that other thread then unlocks the page, the wakeup event will be repeated. So any other pending waiters will now get properly woken up.

Tim Chen and Kan Liang have been battling a customer load that shows extremely long page wakeup lists. The cause seems to be constant NUMA migration of a hot page that is shared across a lot of threads, but the actual root cause for the exact behavior has not been found. Tim has a patch that batches the wait list traversal at wakeup time, so that we at least don't get long uninterruptible cases where we traverse and wake up thousands of processes and get nasty latency spikes. That is likely 4.14 material, but we're still discussing the page waitqueue specific parts of it. In the meantime, I've tried to look at making the page wait queues less expensive, and failing miserably. If you have thousands of threads waiting for the same page, it will be painful. We'll need to try to figure out the NUMA balancing issue some day, in addition to avoiding the excessive spinlock hold times. That said, having tried to rewrite the page wait queues, I can at least fix up some of the braindamage in the current situation. In particular: (a) we don't want to continue walking the page wait list if the bit we're waiting for already got set again (which seems to be one of the patterns of the bad load). That makes no progress and just causes pointless cache pollution chasing the pointers. (b) we don't want to put the non-locking waiters always on the front of the queue, and the locking waiters always on the back. Not only is that unfair, it means that we wake up thousands of reading threads that will just end up being blocked by the writer later anyway. Also add a comment about the layout of 'struct wait_page_key' - there is an external user of it in the cachefiles code that means that it has to match the layout of 'struct wait_bit_key' in the two first members. It so happens to match, because 'struct page *' and 'unsigned long *' end up having the same values simply because the page flags are the first member in struct page.

We have a MAX_LFS_FILESIZE macro that is meant to be filled in by filesystems (and other IO targets) that know they are 64-bit clean and don't have any 32-bit limits in their IO path. It turns out that our 32-bit value for that limit was bogus. On 32-bit, the VM layer is limited by the page cache to only 32-bit index values, but our logic for that was confusing and actually wrong. We used to define that value to (((loff_t)PAGE_SIZE << (BITS_PER_LONG-1))-1) which is actually odd in several ways: it limits the index to 31 bits, and then it limits files so that they can't have data in that last byte of a page that has the highest 31-bit index (ie page index 0x7fffffff). Neither of those limitations make sense. The index is actually the full 32 bit unsigned value, and we can use that whole full page. So the maximum size of the file would logically be "PAGE_SIZE << BITS_PER_LONG". However, we do wan tto avoid the maximum index, because we have code that iterates over the page indexes, and we don't want that code to overflow. So the maximum size of a file on a 32-bit host should actually be one page less than the full 32-bit index. So the actual limit is ULONG_MAX << PAGE_SHIFT. That means that we will not actually be using the page of that last index (ULONG_MAX), but we can grow a file up to that limit. The wrong value of MAX_LFS_FILESIZE actually caused problems for Doug Nazar, who was still using a 32-bit host, but with a 9.7TB 2 x RAID5 volume. It turns out that our old MAX_LFS_FILESIZE was 8TiB (well, one byte less), but the actual true VM limit is one page less than 16TiB. This was invisible until commit c2a9737f ("vfs,mm: fix a dead loop in truncate_inode_pages_range()"), which started applying that MAX_LFS_FILESIZE limit to block devices too. NOTE! On 64-bit, the page index isn't a limiter at all, and the limit is actually just the offset type itself (loff_t), which is signed. But for clarity, on 64-bit, just use the maximum signed value, and don't make people have to count the number of 'f' characters in the hex constant. So just use LLONG_MAX for the 64-bit case. That was what the value had been before too, just written out as a hex constant. Fixes: c2a9737f ("vfs,mm: fix a dead loop in truncate_inode_pages_range()") Reported-and-tested-by:

Pull powerpc fix from Michael Ellerman: "Just one fix, to add a barrier in the switch_mm() code to make sure the mm cpumask update is ordered vs the MMU starting to load translations.

Thanks to Benjamin Herrenschmidt, Nicholas Piggin" * tag 'powerpc-4.13-8' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: powerpc/mm: Ensure cpumask update is ordered
