[ Upstream commit 2e46477a12f6fd273e31a220b155d66e8352198c ]

Remove optimize_div() from BPF_MOD | BPF_K case
since we don't know the dividend and fix the
emit_mod() by reading the mod operation result from HI register

Pull x86 fixes from Thomas Gleixner:
 "Two final fixlets for 3.18:
   - Prevent microcode reload wreckage on 32bit
   - Unbreak cross compilation"

* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86, microcode: Limit the microcode reloading to 64-bit for now
  x86: Use $(OBJDUMP) instead of plain objdump

Commit eb7e7d76 "s390: Replace __get_cpu_var uses" broke machine check
handling.

We copy machine check information from per-cpu to a stack variable for
local processing. Next we should zap the per-cpu variable, not the
stack variable.

First, there was this: https://bugzilla.kernel.org/show_bug.cgi?id=88001

The problem there was that microcode patches are not being reapplied
after suspend-to-ram. It was important to reapply them, though, because
of for example Haswell's TSX erratum which disabled TSX instructions
with a microcode patch.

A simple fix was fb86b97300d9 ("x86, microcode: Update BSPs microcode
on resume") but, as it is often the case, simple fixes are too
simple. This one causes 32-bit resume to fail:

https://bugzilla.kernel.org/show_bug.cgi?id=88391

Properly fixing this would require more involved changes for which it
is too late now, right before the merge window. Thus, limit this to
64-bit only temporarily.

Pull ARM SoC fixes from Arnd Bergmann:
 "Not much interesting going on fixes-wise for us this week, as it
  should be for an -rc7.  I'm not expecting Olof to work much over
  Thanksgiving weekend, so I decided to take over again and push these
  out to you.

  Just four simple fixes this week:

   - one missing of_node_put() on armv7 based mvebu
   - forcing the USB host into the right mode on Chromebook
     (exynos5-snow)
   - enabling two important drivers for exynos_defconfig
   - fixing a noncritical bug for tegra that would cause a regression
     with common code patches queued for 3.19"

Pull ARM fixes from Russell King:
 "Another round of relatively small ARM fixes.

  Thomas spotted that the strex backoff delay bit was a disable bit, so
  it needed to be clear for this to work.  Vladimir spotted that using a
  restart block for the cache flush operation would return -EINTR, which
  userspace was not expecting.  Dmitry spotted that the auxiliary
  control register accesses for Xscale were not correct"
