At r360808, make buildkernel fails with:
--- kbdmux.o ---
/usr/src/sys/dev/kbdmux/kbdmux.c:464:10: error: use of undeclared identifier 'key_map'; did you mean 'keymap'?
bcopy(&key_map, keymap, sizeof(key_map));
This is apparently related to the use of the following options in the config file:
If I remove them, the build completes successfully, but it did with them enabled at least until r360560.
I retried this build since then with KBDMUX_DFLT_KEYMAP enabled (at r361008 but there does not seen to have been relevant changes since my initial report), and have been unable to reproduce the issue.
Maybe I somehow blundered the first time. Another possibility would be some race issue (I build with make -j 2)
(In reply to Philippe Michel from comment #1)
I will close the bug for now, then. If it occurs again, please re-open, and provide the contents of kbdmuxmap.h from the kernel object directory.
