Previously, closing a SPE gang that still has contexts would trigger
a WARN_ON, and leak the allocated gang.
This change fixes the problem by using the gang's reference counts to
destroy the gang instead. The gangs will persist until their last
reference (be it context or open file handle) is gone.
Also, avoid using statements with side-effects in a WARN_ON().

This refuses to load the module on platforms that have no

The write path code intends to bug if a math error (or unhandled case)
results in a write outside of the current cluster boundaries. The actual
BUG_ON() statements however are incorrect, leading to a crash on kernels
with 64k page size. Fix those by checking against the right variables.
Also, move the assertions higher up within the functions so that they trip
*before* the code starts to mark buffers.

(currently) no way turn on signatures in such case, I had to force NT

The warnings happens because the function: promcon_init_unimap()
references promfont_unitable and promfont_unicount which are marked
__initdata by the conmakehash command in the drivers/video/console/Makefile
Fix the warning by removing the __initdata marker on the two variables.

Several people have reported LITE-ON LTR-48246S detection failed
because SETXFER fails. It seems the device raises IRQ too early after
SETXFER. This is controller independent. The same problem has been
reported for different controllers.
So, now we have pata_via where the controller raises IRQ before it's
ready after SETXFER and a device which does similar thing. This patch
makes libata always execute SETXFER via polling. As this only happens
during EH, performance impact is nil. Setting ATA_TFLAG_POLLING is
also moved from issue hot path to ata_dev_set_xfermode() - the only
place where SETXFER can be issued.
Note that ATA_TFLAG_POLLING applies only to drivers which implement
SFF TF interface and use libata HSM. More advanced controllers ignore
the flag. This doesn't matter for this fix as SFF TF controllers are
the problematic ones.
