Missing kernel configuration file(s)

[Коньков Евгений]

I have upgrade src to Revision: 234068

# cd /usr/src
# make -j 8 buildkernel KERNCONF=KES_KERN_v10
ERROR: Missing kernel configuration file(s) (KES_KERN_v10).
*** Error code 1
1 error
*** Error code 2
1 error
# cd /usr/src/sys/amd64/conf
# ls
.cvsignore      GENERIC.hints                   Makefile
DEFAULTS        KESOPTS         LINT            NOTES
GENERIC         KES_KERN_v10    LINT-VIMAGE     XENHVM

I always do this steps, but now I get errors.
I can not find what was changed.
How I must compile my kernel now?
