For the !CC_AS_ASM_GOTO_OUTPUT (aka. the legacy codepath), remove the .fixup usage by employing both EX_TYPE_EFAULT_REG and EX_FLAG_CLEAR. Like was already done for X86_32's version of __get_user_asm_u64() use the "a" register for output, specifically so we can use CLEAR_AX.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
