Takashi Sakamoto 91d2178e26 ALSA: timer: fix gparams ioctl compatibility for different architectures
'struct snd_timer_gparams' includes some members with 'unsigned long',
therefore its size differs depending on data models of architecture. As
a result, x86/x32 applications fail to execute ioctl(2) with
SNDRV_TIMER_GPARAMS command on x86_64 machine.

This commit fixes this bug by adding a pair of structure and ioctl
command for the compatibility.

Takashi Iwai b24e7ad1fd ALSA: timer: Fix ioctls for X32 ABI
X32 ABI takes the 64bit timespec, thus the timer user status ioctl becomes
incompatible with IA32.  This results in NOTTY error when the ioctl is
issued.

Meanwhile, this struct in X32 is essentially identical with the one in
X86-64, so we can just bypassing to the existing code for this
specific compat ioctl.

Takashi Iwai 3a72494ac2 ALSA: timer: Fix broken compat timer user status ioctl
The timer user status compat ioctl returned the bogus struct used for
64bit architectures instead of the 32bit one.  This patch addresses
it to return the proper struct.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
