The CRYPTO one I've definitely hit a few times (usually combined with
CRYPTO_HASH) and a failure to link crypto_ahash_* functions.

Otherwise it's mostly CRC32 and a couple of odd ones like this that I've
seen so far:

ERROR: modpost: "dell_privacy_has_mic_mute"
[drivers/platform/x86/dell/dell-laptop.ko] undefined!

CC drivers/scsi/aic7xxx/aic79xx_reg_print.o
gcc: error: drivers/scsi/aic7xxx/aic79xx_reg_print.c: No such file or
directory
gcc: fatal error: no input files
compilation terminated.
make[3]: *** [scripts/Makefile.build:271:
drivers/scsi/aic7xxx/aic79xx_reg_print.o] Error 1

I'll give your suggestions a try, I have about 9 patches queued up so
far so I think there are definitely more problems lurking around.

Thanks,


Vegard
