Hans de Goede 52e1cf2d19 efi/libstub/tpm: Initialize efi_physical_addr_t vars to zero for mixed mode ... Commit: 79832f0b5f ("efi/libstub/tpm: Initialize pointer variables to zero for mixed mode") fixes a problem with the tpm code on mixed mode (64-bit kernel on 32-bit UEFI), where 64-bit pointer variables are not fully initialized by the 32-bit EFI code. A similar problem applies to the efi_physical_addr_t variables which are written by the ->get_event_log() EFI call. Even though efi_physical_addr_t is 64-bit everywhere, it seems that some 32-bit UEFI implementations only fill in the lower 32 bits when passed a pointer to an efi_physical_addr_t to fill. This commit initializes these to 0 to, to ensure the upper 32 bits are 0 in mixed mode. This fixes recent kernels sometimes hanging during early boot on mixed mode UEFI systems.
