Merge tag 'hardening-v6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull hardening updates from Kees Cook:

 - string: Add missing kernel-doc return descriptions (Kriish Sharma)

 - Update some mis-typed allocations

   These correct some accidentally wrong types used in allocations (that
   didn't affect the resulting size) that never got picked up from the
   batch I sent a few months ago.

 - Enable GCC diagnostic context for value-tracking warnings

   This results in better GCC diagnostics for the value range tracking,
   so we can get better visibility into where those values are coming
   from when we get out-of-bounds warnings at compile time.
