Merge tag 'modules-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux

Pull module update from Rusty Russell:
 "Nothing major: support for compressing modules, and auto-tainting
  params.

  PS. My virtio-next tree is empty: DaveM took the patches I had.  There
      might be a virtio-rng starvation fix, but so far it's a bit voodoo
      so I will get to that in the next two days or it will wait"

* tag 'modules-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux:
  moduleparam: Resolve missing-field-initializer warning
  kbuild: handle module compression while running 'make modules_install'.
  modinst: wrap long lines in order to enhance cmd_modules_install
  modsign: lookup lines ending in .ko in .mod files
  modpost: simplify file name generation of *.mod.c files
  modpost: reduce visibility of symbols and constify r/o arrays
  param: check for tainting before calling set op.
  drm/i915: taint the kernel if unsafe module parameters are set
  module: add module_param_unsafe and module_param_named_unsafe
  module: make it possible to have unsafe, tainting module params
  module: rename KERNEL_PARAM_FL_NOARG to avoid confusion

+
+          The modules will be compressed either using gzip or xz depend on the
+          choice made in "Compression algorithm".
+
+          module-init-tools has support for gzip format while kmod handle gzip
+          and xz compressed modules.
+
+          When a kernel module is installed from outside of the main kernel
+          source and uses the Kbuild system for installing modules then that
+          kernel module will also be compressed when it is installed.
+
+          This option provides little benefit when the modules are to be used inside
+          an initrd or initramfs, it generally is more efficient to compress the whole
+          initrd or initramfs instead.
+
+          This is fully compatible with signed modules while the signed module is
+          compressed. module-init-tools or kmod handles decompression and provide to
+          other layer the uncompressed but signed payload.
