      x86/microcode: Do the family check first · 1f161f67
      由 Borislav Petkov 提交于 
      On CPUs like AMD's Geode, for example, we shouldn't even try to load
microcode because they do not support the modern microcode loading
interface.

However, we do the family check *after* the other checks whether the
loader has been disabled on the command line or whether we're running in
a guest.

So move the family checks first in order to exit early if we're being
loaded on an unsupported family.

      locking/lockdep: Disable cross-release features for now · b483cf3b
      由 Ingo Molnar 提交于 
      Johan Hovold reported a big lockdep slowdown on his system, caused by lockdep:

> I had noticed that the BeagleBone Black boot time appeared to have
> increased significantly with 4.14 and yesterday I finally had time to
> investigate it.
>
> Boot time (from "Linux version" to login prompt) had in fact doubled
> since 4.13 where it took 17 seconds (with my current config) compared to
> the 35 seconds I now see with 4.14-rc4.
>
> I quick bisect pointed to lockdep and specifically the following commit:
>
>	28a903f6 ("locking/lockdep: Handle non(or multi)-acquisition of a crosslock")

Because the final v4.14 release is close, disable the cross-release lockdep
features for now.

      Pull MIPS fixes from Ralf Baechle:
 "More MIPS fixes for 4.14:

   - Loongson 1: Set the default number of RX and TX queues to
     accomodate for recent changes of stmmac driver.

   - BPF: Fix uninitialised target compiler error.

   - Fix cmpxchg on 32 bit signed ints for 64 bit kernels with
     !kernel_uses_llsc

   - Fix generic-board-config.sh for builds using O=

   - Remove pr_err() calls from fpu_emu() for a case which is not a
     kernel error"
