Pull x86 platform-driver updates from Darren Hart:
 "New model support added for Dell, Ideapad, Acer, Asus, Thinkpad, and
  GPD laptops. Improvements to the common intel-vbtn driver, including
  tablet mode, rotate, and front button support. Intel CPU support added
  for Cannonlake and platform support for Dollar Cove power button.

  Overhaul of the mellanox platform driver, creating a new
  platform/mellanox directory for the newly multi-architecture regmap
  interface.

  Significant Intel PMC update with CannonLake support, Coffeelake
  update, CPUID enumeration, module support, new read64 API, refactoring
  and cleanups.

  Revert the apple-gmux iGP IO lock, addressing reported issues with
  non-binary drivers, leaving Nvidia binary driver users to comment out
  conflicting code.

Pull more rdma updates from Doug Ledford:
 "Items of note:

   - two patches fix a regression in the 4.15 kernel. The 4.14 kernel
     worked fine with NVMe over Fabrics and mlx5 adapters. That broke in
     4.15. The fix is here.

   - one of the patches (the endian notation patch from Lijun) looks

     nature. It amounts to the biggest chunk of change in it (it's about
     2/3rds of the overall pull request).

  Summary:

   - Clean up some function signatures in rxe for clarity

   - Tidy the RDMA netlink header to remove unimplemented constants

   - bnxt_re driver fixes, one is a regression this window.

   - Minor hns driver fixes

Currently the async EQ has 256 entries only. It might not be big enough
for the SW to handle all the needed pending events. For example, in case
of many QPs (let's say 1024) connected to a SRQ created using NVMeOF target
and the target goes down, the FW will raise 1024 "last WQE reached" events
and may cause EQ overrun. Increase the EQ to more reasonable size, that beyond
it the FW should be able to delay the event and raise it later on using internal
backpressure mechanism.

A re-factoring patch in NFS export series has passed the wrong argument
to ovl_get_inode() causing a regression in the very recent fix to
fsnotify of overlay merge dir.

The regression has caused merge directory inodes to be hashed by upper
instead of lower real inode, when NFS export and directory indexing is
disabled. That caused an inotify watch to become obsolete after directory
copy up and drop caches.

LTP test inotify07 was improved to catch this regression.
The regression also caused multiple redirect dirs to same origin not to
be detected on lookup with NFS export disabled. An xfstest was added to
cover this case.

     touched.

   - The initial IBPB support and its usage in context switch

   - The exposure of the new speculation MSRs to KVM guests.

   - A fix for a regression in x86/32 related to the cpu entry area

   - Proper whitelisting for known to be safe CPUs from the mitigations.

   - objtool fixes to deal proper with retpolines and alternatives

   - Exclude __init functions from retpolines which speeds up the boot
     process.

   - Removal of the syscall64 fast path and related cleanups and
     simplifications

   - Removal of the unpatched paravirt mode which is yet another source
     of indirect unproteced calls.

   - A new and undisputed version of the module mismatch warning

   - A couple of cleanup and correctness fixes all over the place

  Yet another step towards full mitigation. There are a few things still
  missing like the RBS underflow mitigation for Skylake and other small
  details, but that's being worked on.

  That said, I'm taking a belated christmas vacation for a week and hope
  that everything is magically solved when I'm back on Feb 12th"

     though the request isn't carrying real data. Also fixes a bio-to-rq

     This can cause scalability concerns on bigger machines and

 "This makes the f2fs symlink code use the fscrypt_encrypt_symlink()
  from the fscrypt tree. This will end up dropping the kzalloc() ->

  won't get tested by f2fs's kmalloc error injection system; which is
  fine"

Intel CoffeeLake SoC uses CPU ID of KabyLake but has Cannonlake PCH, so in
this case PMC register details from Cannonlake PCH must be used.

In order to identify whether the given platform is Coffeelake, scan for the
Sunrisepoint PMC PCI Id.
