[Thomas Nikolajsen]

buildkernel fails after this commit:

linking kernel.debug
hammer_mirror.o: In function `hammer_ioc_mirror_read':
/usr/src/sys/vfs/hammer/hammer_mirror.c:259: undefined reference to `crc32_ext'

Seems like you forgot to commit file with crc32_ext();
I guess you have something like patch below.
