VDSO_HAS_32BIT_FALLBACK was introduced to address a regression which caused seccomp to deny access to the applications to clock_gettime64() and clock_getres64() because they are not enabled in the existing filters. The purpose of VDSO_HAS_32BIT_FALLBACK was to simplify the conditional implementation of __cvdso_clock_get*time32() variants. Now that all the architectures that support the generic vDSO library have been converted to support the 32 bit fallbacks the conditional can be removed.

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.
