There is a problem in some hardware where the kernel will stall for
35 seconds waiting for disks that don't exist. This patch will skip
waiting for the BSY-bit on IDE drives to go away if you set "hdx=noprobe"
as a kernel option and the disk is not marked as 'present' (like when
you set the geometry by hand).
If no noprobe-option is set the code will work (more or less) as the
original but if set the code will skip the ide_wait_not_busy() for
that drive. Even if there would be a drive there and it is still busy
afterwards it should not matter since it isn't probed for later.
The code also honors the MAX_DRIVES variable instead of assuming that
there will be two harddrives on the bus.

The intent behind siimage_reset() was probably to hard reset the interface and
the SATA PHY but as the code writes to two reserved bits instead, it obviously
has been ineffective from the start. So, just remove it.

Plip passes a string "name" that is allocated on stack to

"name" and when the registering function exits, it points nowhere.
On some machine, this bug causes bad names to appear in /proc, such as
/proc/sys/dev/parport/parport0/devices/T^/�X^/�, on others, the plip
proc node is completely missing.

For a kernel built with "make ARCH=x86" the following system
information is displayed when running the new kernel
$ uname -m
x86
On some i386 systems (e.g. K7) we even have the following information
$ uname -m
x66
This is weird. The usual information for "uname -m" should be "x86_64"
on 64-bit and "i386" or "i686" on 32-bit.
This patch fixes the issue by setting UTS_MACHINE to "i386" for 32-bit
kernel builds and to "x86_64" for 64-bit kernel builds. I.e., "x86"
won't be used for UTS_MACHINE anymore.
