Pull compiler_types.h fix from Miguel Ojeda:
 "A cleanup for userspace in compiler_types.h: don't pollute userspace
  with macro definitions (Xiaozhou Liu)

  This is harmless for the kernel, but v4.19 was released with a few
  macros exposed to userspace as the patch explains; which this removes,
  so it *could* happen that we break something for someone (although
  leaving inline redefined is probably worse)"

oversight.

Pull x86 fixes from Ingo Molnar:
 "The biggest part is a series of reverts for the macro based GCC
  inlining workarounds. It caused regressions in distro build and other
  kernel tooling environments, and the GCC project was very receptive to
  fixing the underlying inliner weaknesses - so as time ran out we
  decided to do a reasonably straightforward revert of the patches. The
  plan is to rely on the 'asm inline' GCC 9 feature, which might be
  backported to GCC 8 and could thus become reasonably widely available
  on modern distros.

  Other than those reverts, there's misc fixes from all around the
  place.

  I wish our final x86 pull request for v4.20 was smaller..."

mm/sparse: add common helper to mark all memblocks present

2018-12-14T23:05:45+00:00

Presently the arches arm64, arm and sh have a function which loops
through each memblock and calls memory present.  riscv will require a
similar function.

Introduce a common memblocks_present() function that can be used by all
the arches.  Subsequent patches will cleanup the arches that make use of
this.

mm: introduce common STRUCT_PAGE_MAX_SHIFT define

2018-12-14T23:05:45+00:00

This define is used by arm64 to calculate the size of the vmemmap
region.  It is defined as the log2 of the upper bound on the size of a
struct page.

We move it into mm_types.h so it can be defined properly instead of set
and checked with a build bug.  This also allows us to use the same
define for riscv.
