In an effort of optimising SNDRV_PCM_IOCTL_SYNC_PTR ioctl which is a hot path, lets first refactor the copy from and to user with macros. This is done with macros and not static inline fonctions because types differs between the different versions of snd_pcm_sync_ptr() like functions. First step is to refactor only snd_pcm_ioctl_sync_ptr_compat() and snd_pcm_ioctl_sync_ptr_x32() as it would be a performance regression for snd_pcm_sync_ptr() and snd_pcm_ioctl_sync_ptr_buggy() for now. They may be refactored after next patch.

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 reStructuredText 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.
