In the clock_gettime / clock_gettime64 syscalls based gettimeofday(), there is no way to let kernel space 'fixup' the invalid data pointer of 'struct timeval' and 'struct timezone' for us for we need to read timespec from kernel space and then convert to timeval in user-space ourselves and also we need to simply ignore and reset timezone in user-space. Without this removal, the invalid (void *)1 address will trigger a sigsegv (signum = 11) signal and stop the whole test.

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.
