[SCSI] mpt fusion: fix for mounted raid volume filesytem that goes read-only
If there is IO going to the volume while a hidden disk is being torn down,
there is a case where we would return a DID_NO_CONNECT for IO sent to the
volume. The end result is the volume goes read-only. This problem is due to the
fact the firmware mapped target ids saved in per device object is phys_disk_num
for hidden raid components, and target_id for the volume. There is a single
case when both phys_disk_num and target_id are equal, so enters this issue. We
fix this issue by checking the tflags when the device is torned down,
insuring the IO being completed is meant for hidden raid component, not the
volume. In addition to this fix, there are a couple other cases to address
hidden raid components. For instance task_abort and device reset are not
supported by mpt fw for hidden raid components, a bus reset would be required
or target reset to volume.

[SCSI] a100u2w: Convert into Linux style
I was investigating strange driver behaviour and thought that readable
code and proper visible types might help explain why it didn't work right
the moment a second SCB was outstanding to the controller. I was right
- Cleanup, linuxise, demacro
- Remove the BSD dual licence on the new work
- Switch the if ALPHA to if __LP64__. (struct size is then right
elsewhere) and then to CONFIG_64BIT as per Christoph's request
- Fix the recursive locking on a reset. This is the only actual real code
change (I hope ;)).
I'm not clear what the right way to handle the BIOS param stuff is on n
on x86-32/64. Using phys_to_virt and stuff is ugly and probably doesn't
make sense elsewhere
Still has a couple of odd things - and there seems to be a commonly shared
EEPROM handling error several drivers have. Roughly speaking several SCSI
drivers go
try and read EEPROM
It failed..
Write any changes between the default and the data we read
Which is great as for some paths we've no idea what was in
before, so each boot won't write it all back, won't checksum but will
repeat the bug
Also it can still sleep for a second with IRQ off, and there is some
dubious looking error path locking marked FIXME in case anyone feels
inspired to work on it. Not a newly introduced bug, and at least its now
marked.

We subtract 12 off 'fp' before testing to see if it's below the low

NOHZ: prevent multiplication overflow - stop timer for huge timeouts
get_next_timer_interrupt() returns a delta of (LONG_MAX > 1) in case
there is no timer pending. On 64 bit machines this results in a
multiplication overflow in tick_nohz_stop_sched_tick().
Reported by: Dave Miller <davem@davemloft.net>
Make the return value a constant and limit the return value to a 32 bit
value.
When the max timeout value is returned, we can safely stop the tick
timer device. The max jiffies delta results in a 12 days timeout for
HZ=1000.
In the long term the get_next_timer_interrupt() code needs to be
reworked to return ktime instead of jiffies, but we have to wait until
the last users of the original NO_IDLE_HZ code are converted.
