The VBI DMA is handled in a special way and is marked with a bit.
However, that bit was set at the wrong time and could be cleared
by mistake if a PCM (or other) DMA request would arrive before the
VBI DMA was completed. So on completion of the VBI DMA the driver
no longer knew that that DMA transfer was for VBI data. And this
in turn caused havoc with the card's DMA engine.

Small variables that would otherwise be in .data or .bss may, depending on the

instruction references on fixed instruction width machines.
__start_notes and __stop_notes aren't really char variables, and certainly

libata: implement EH fast drain
In most cases, when EH is scheduled, all in-flight commands are
aborted causing EH to kick in immediately. However, in some cases
(especially with PMP), it's unclear which commands are affected by the
error condition and although aborting all in-flight commands work, it
isn't optimal and may cause unnecessary disruption. On the other
hand, waiting for in-flight commands to drain themselves can take up
to 30seconds.
This patch implements EH fast drain to handle such situations. It
gives in-flight commands some time to finish up but doesn't wait for
too long. After EH is scheduled, fast drain timer is started and if
no other completion occurs in ATA_EH_FASTDRAIN_INTERVAL all in-flight
commands are aborted. If any completion occurred in the interval, the
port is given another interval to finish up itself.
Currently ATA_EH_FASTDRAIN_INTERVAL is 3 secs which should be enough
for finishing up most commands.

libata: add @is_cmd to ata_tf_to_fis()
Add @is_cmd to ata_tf_to_fis(). This controls bit 7 of the second
byte which tells the device whether this H2D FIS is for a command or
not. This cleans up ahci a bit and will be used by PMP.

[libata] Fix reported task file values in sense data
ata_tf_read was setting HOB bit when lba48 command was submitted, but
was not clearing it before reading "normal" data. As it is only place
which sets HOB bit in control register, and register reads should not
be affected by other bits, let's just clear it when we are done with
reading upper bytes so non-48bit commands do not have to touch ctl
at all.
pata_scc suffered from same problem...

Correct comment in libata-sff.c
The filename in the file header is incorrect.
