c - Field ' ' could not be resolved -

currently trying compile kernel module in userspace. module is

aes_generic.c 

so far commented kernel headers , started fixing compile errors u8 not available simpyl replaced uint8_t these errors gone now

i struggling error field '' not resolved

this error appears in various fields

here's example:

#define loop8(i)    { \ loop8tophalf(i); \ t  = ctx->key_enc[8 * + 4] ^ ls_box(t); \ ctx->key_enc[8 * + 12] = t;           \ t ^= ctx->key_enc[8 * + 5];           \ ctx->key_enc[8 * + 13] = t;           \ t ^= ctx->key_enc[8 * + 6];           \ ctx->key_enc[8 * + 14] = t;           \ t ^= ctx->key_enc[8 * + 7];           \ ctx->key_enc[8 * + 15] = t;           \ } while (0) 

error:

field 'loop8(i)' not resolved 

more code same error message:

edit: these errors fixed, manually editiong aes.h , including in userspace file help
