Mark Lord 2b06719153 libata bugfix: HDIO_DRIVE_TASK 
I was trying to use HDIO_DRIVE_TASK for something today,
and discovered that the libata implementation does not copy
over the upper four LBA bits from args[6].

This is serious, as any tools using this ioctl would have their
commands applied to the wrong sectors on the drive, possibly resulting
in disk corruption.

Ideally, newer apps should use SG_IO/ATA_16 directly,
avoiding this bug.  But with libata poised to displace drivers/ide,
better compatibility here is a must.

This patch fixes libata to use the upper four LBA bits passed
in from the ioctl.

The original drivers/ide implementation copies over all bits
except for the master/slave select bit.  With this patch,
libata will copy only the four high-order LBA bits,
just in case there are assumptions elsewhere in libata (?).
