RPI2 World build stopped in /usr/src/sys/boot/efi/boot1

[bob prohaska]

Hi all,

Buildworld stopped with
--- all_subdir_sys ---
/usr/src/sys/boot/efi/boot1/zfs_module.c:139:18: error: format specifies type 'size_t' (aka 'unsigned int') but the argument has type 'off_t' (aka 'long long') [-Werror,-Wformat]
                    "(%lu)\n", st.st_size, spa->spa_name, filepath, EFI_ERROR_CODE(status));
                               ^~~~~~~~~~
1 error generated.
*** [zfs_module.o] Error code 1

make[6]: stopped in /usr/src/sys/boot/efi/boot1

I just tried re-running svnlite update, the cited file didn't change.
The source tree is at 295345, building system is at r295306M (M for
added debugging in the RPI2 kernel).

This looks like a problem with the source tree, please clue me in
if I should look closer to home.

Thanks for reading and any guidance,
