Two omap fixes for v4.18-rc cycle

Turns out the recent patches for ARM branch predictor hardening are
not working on omap5 and dra7 as planned because the secondary CPU
is parked to the bootrom code. 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. The
usb otg module on am3517 is not the same as for other omap3.

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.

The reason is that the length of the new brk is not page aligned when we
try to populate the it.  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.

The warning is basically saying that a top-down allocation can break
memory hotremove because memblock allocation is not movable.  But m68k
doesn't even support MEMORY_HOTREMOVE so there is no point to warn about
it.

Make the warning conditional only to configurations that care.

- Build the kernel without the fix

- 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.

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.

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 493b0e9d (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.

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.

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 124049de ("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().

Pull arm64 fixes from Will Deacon:
 "Catalin's out enjoying the sunshine, so I'm sending the fixes for a
  couple of weeks (although there hopefully won't be any more!).

  We've got a revert of a previous fix because it broke the build with
  some distro toolchains and a preemption fix when detemining whether or
  not the SIMD unit is in use.

  Summary:

   - Revert back to the 'linux' target for LD, as 'elf' breaks some
     distributions

   - Fix preemption race when testing whether the vector unit is in use
     or not"

Pull tracing fixlet from Steven Rostedt:
 "Joel Fernandes asked to add a feature in tracing that Android had its
  own patch internally for. 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"
