We can't configure it in the bootloader. So we must enable invalidates of BTB for omap5 and dra7 secondary core in the kernel. And there's a fix for reserved register access for am3517.

4 daysreiserfs: fix buffer overflow with long warning messagesEric Biggers
ReiserFS prepares log messages into a 1024-byte buffer with no bounds checks. Long messages, such as the "unknown mount option" warning when userspace passes a crafted mount options string, overflow this buffer. This causes KASAN to report a global-out-of-bounds write. Fix it by truncating messages to the buffer size.

There is no reason to bug on that though. do_brk_flags already aligns the length properly so the mapping is expanded as it should. All we need is to tell mm_populate about it. Besides that there is absolutely no reason to to bug_on in the first place. The worst thing that could happen is that the last page wouldn't get populated and that is far from putting system into an inconsistent state. Fix the issue by moving the length sanitization code from do_brk_flags up to vm_brk_flags. The only other caller of do_brk_flags is brk syscall entry and it makes sure to provide the proper length so t here is no need for sanitation and so we can use do_brk_flags without it. Also remove the bogus BUG_ONs.

- Build the kernel without the fix - Add some flag to the purgatories KBUILD_CFLAGS,I used -fno-asynchronous-unwind-tables - Re-build the kernel When you look at makes output you see that sha256.o is not re-build in the last step. Also readelf -S still shows the .eh_frame section for sha256.o. With the fix sha256.o is rebuilt in the last step. Without FORCE make does not detect changes only made to the command line options. So object files might not be re-built even when they should be. Fix this by adding FORCE where it is missing.

4 daysnet/9p/client.c: put refcount of trans_mod in error case in parse_opts()piaojun
In my testing, the second mount will fail after umounting successfully. The reason is that we put refcount of trans_mod in the correct case rather than the error case in parse_opts() at last. That will cause the refcount decrease to -1, and when we try to get trans_mod again in try_module_get(), we could only increase refcount to 0 which will cause failure as follows: parse_opts v9fs_get_trans_by_name try_module_get : return NULL to caller which cause error So we should put refcount of trans_mod in error case.

4 daysmm: allow arch to supply p??_free_tlb functionsNicholas Piggin
The mmu_gather APIs keep track of the invalidated address range including the span covered by invalidated page table pages. Ranges covered by page tables but not ptes (and therefore no TLBs) still need to be invalidated because some architectures (x86) can cache intermediate page table entries, and invalidate those with normal TLB invalidation instructions to be almost-backward-compatible. Architectures which don't cache intermediate page table entries, or which invalidate these caches separately from TLB invalidation, do not require TLB invalidation range expanded over page tables. Allow architectures to supply their own p??_free_tlb functions, which can avoid the __tlb_adjust_range.

Thomas reports: "While looking around in /proc on my v4.14.52 system I noticed that all processes got a lot of "Locked" memory in /proc/*/smaps. A lot more memory than a regular user can usually lock with mlock(). Commit 493b0e9d945f (in v4.14-rc1) seems to have changed the behavior of "Locked". Before that commit the code was like this. Notice the VM_LOCKED check. (vma->vm_flags & VM_LOCKED) ? (unsigned long)(mss.pss >> (10 + PSS_SHIFT)) : 0); After that commit Locked is now the same as Pss: (unsigned long)(mss->pss >> (10 + PSS_SHIFT))); This looks like a mistake." Indeed, the commit has added mss->pss_locked with the correct value that depends on VM_LOCKED, but forgot to actually use it. Fix it.

4 daysmm: do not drop unused pages when userfaultd is runningChristian Borntraeger
KVM guests on s390 can notify the host of unused pages. This can result in pte_unused callbacks to be true for KVM guest memory. If a page is unused (checked with pte_unused) we might drop this page instead of paging it. This can have side-effects on userfaultd, when the page in question was already migrated: The next access of that page will trigger a fault and a user fault instead of faulting in a new and empty zero page. As QEMU does not expect a userfault on an already migrated page this migration will fail. The most straightforward solution is to ignore the pte_unused hint if a userfault context is active for this VMA.

4 daysmm: zero unavailable pages before memmap initPavel Tatashin
We must zero struct pages for memory that is not backed by physical memory, or kernel does not have access to. Recently, there was a change which zeroed all memmap for all holes in e820. Unfortunately, it introduced a bug that is discussed here: https://www.spinics.net/lists/linux-mm/msg156764.html Linus, also saw this bug on his machine, and confirmed that reverting commit 124049decbb1 ("x86/e820: put !E820_TYPE_RAM regions into memblock.reserved") fixes the issue. The problem is that we incorrectly zero some struct pages after they were setup. The fix is to zero unavailable struct pages prior to initializing of struct pages. A more detailed fix should come later that would avoid double zeroing cases: one in __init_single_page(), the other one in zero_resv_unavail().

I took it back in 4.13. Now he realizes that he had a mistake, and swapped the values from what Android had. This means that the old Android tools will break when using a new kernel that has the new feature on it. The options are: 1. To swap it back to what Android wants. 2. Add a command line option or something to do the swap 3. Just let Android carry a patch that swaps it back Since it requires setting a tracing option to enable this anyway, I doubt there are other users of this than Android. Thus, I've decided to take option 1. If someone else is actually depending on the order that is in the kernel, then we will have to revert this change and go to option 2 or 3" * tag 'trace-v4.18-rc3-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Reorder display of TGID to be after PID

5 daysxen: setup pv irq ops vector earlierJuergen Gross
Setting pv_irq_ops for Xen PV domains should be done as early as possible in order to support e.g. very early printk() usage. The same applies to xen_vcpu_info_reset(0), as it is needed for the pv irq ops. Move the call of xen_setup_machphys_mapping() after initializing the pv functions as it contains a WARN_ON(), too. Remove the no longer necessary conditional in xen_init_irq_ops() from PVH V1 times to make clear this is a PV only function.

5 daystracing: Reorder display of TGID to be after PIDJoel Fernandes (Google)
Currently ftrace displays data in trace output like so: _-----=> irqs-off / _----=> need-resched | / _---=> hardirq/softirq || / _--=> preempt-depth ||| / delay TASK-PID CPU TGID |||| TIMESTAMP FUNCTION | | | | |||| | | bash-1091 [000] ( 1091) d..2 28.313544: sched_switch: However Android's trace visualization tools expect a slightly different format due to an out-of-tree patch patch that was been carried for a decade, notice that the TGID and CPU fields are reversed: _-----=> irqs-off / _----=> need-resched | / _---=> hardirq/softirq || / _--=> preempt-depth ||| / delay TASK-PID TGID CPU |||| TIMESTAMP FUNCTION | | | | |||| | | bash-1091 ( 1091) [002] d..2 64.965177: sched_switch: From kernel v4.13 onwards, during which TGID was introduced, tracing with systrace on all Android kernels will break (most Android kernels have been on 4.9 with Android patches, so this issues hasn't been seen yet). From v4.13 onwards things will break. The chrome browser's tracing tools also embed the systrace viewer which uses the legacy TGID format and updates to that are known to be difficult to make. Considering this, I suggest we make this change to the upstream kernel and backport it to all Android kernels. I believe this feature is merged recently enough into the upstream kernel that it shouldn't be a problem. Also logically, IMO it makes more sense to group the TGID with the TASK-PID and the CPU after these.
