Subject: [GIT PULL] Modules updates for v5.9

Hi Linus,

Please pull below to receive modules updates for the v5.9 merge window.
The most important change would be Christoph Hellwig's patch implementing
proprietary taint inheritance, in an effort to discourage the creation of
GPL "shim" modules that interface between GPL symbols and proprietary
symbols. A recent example cited from the discussion can be found here:

Thank you,

Jessica

  modules: inherit TAINT_PROPRIETARY_MODULE (2020-08-05 10:31:28 +0200)

----------------------------------------------------------------
Modules updates for v5.9

Summary of modules changes for the 5.9 merge window:

- Have modules that use symbols from proprietary modules inherit the
  TAINT_PROPRIETARY_MODULE taint, in an effort to prevent GPL shim modules that
  are used to circumvent _GPL exports. These are modules that claim to be GPL
  licensed while also using symbols from proprietary modules. Such modules will
  be rejected while non-GPL modules will inherit the proprietary taint.

- Module export space cleanup. Unexport symbols that are unused outside of
  module.c or otherwise used in only built-in code.
