Since you removed all references for fpregset now, you probably want to remove the declaration of the variable above.

With this code, you removed all the reference for variable pkey_reg_offset, thus, its declaration could be removed also.

Since the variable pkey_reg_ptr is only used for Intel code (inside #ifdefs), you probably want to #ifdef the variable declaration also, avoid triggering "unused variable" warning on non-Intel machines. -- To unsubscribe from this list: send the line "unsubscribe linux-kselftest" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
