Merge tag 'memcpy-v5.18-rc1' of git://git./linux/kernel/git/kees/linux

Pull FORTIFY_SOURCE updates from Kees Cook:
 "This series consists of two halves:

   - strict compile-time buffer size checking under FORTIFY_SOURCE for
     the memcpy()-family of functions (for extensive details and
     rationale, see the first commit)

   - enabling FORTIFY_SOURCE for Clang, which has had many overlapping
     bugs that we've finally worked past"

* tag 'memcpy-v5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux:
  fortify: Add Clang support
  fortify: Make sure strlen() may still be used as a constant expression
  fortify: Use __diagnose_as() for better diagnostic coverage
  fortify: Make pointer arguments const
  Compiler Attributes: Add __diagnose_as for Clang
  Compiler Attributes: Add __overloadable for Clang
  Compiler Attributes: Add __pass_object_size for Clang
  fortify: Replace open-coded __gnu_inline attribute
  fortify: Update compile-time tests for Clang 14
  fortify: Detect struct member overflows in memset() at compile-time
