Pull integrity updates from Mimi Zohar:
 "Just a couple of updates for linux-5.7:

   - A new Kconfig option to enable IMA architecture specific runtime
     policy rules needed for secure and/or trusted boot, as requested.

   - Some message cleanup (eg. pr_fmt, additional error messages)"

* 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity:
  ima: add a new CONFIG for loading arch-specific policies
  integrity: Remove duplicate pr_fmt definitions
  IMA: Add log statements for failure conditions
  IMA: Update KBUILD_MODNAME for IMA files to ima
