Merge tag 'efi-fixes-for-v6.9-3' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi
Pull EFI fixes from Ard Biesheuvel: "These address all the outstanding EFI/x86 boot related regressions: - Revert to the old initrd memory allocation soft limit of INT_MAX, which was dropped inadvertently - Ensure that startup_32() is entered with a valid boot_params pointer when using the new EFI mixed mode protocol - Fix a compiler warning introduced by a fix from the previous pull" * tag 'efi-fixes-for-v6.9-3' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi: x86/efistub: Reinstate soft limit for initrd loading efi/libstub: Cast away type warning in use of max() x86/efistub: Add missing boot_params for mixed mode compat entry
