PNP_MAX_MEM and PNP_MAX_PORT are mainly used to size tables of PNP
device resources. In 2.6.24, we increased their values to accomodate
ACPI devices that have many resources:
2.6.23 2.6.24
------ ------
PNP_MAX_MEM 4 12
PNP_MAX_PORT 8 40
However, ISAPNP also used these constants as the size of parts of the
logical device register set. This register set is fixed by hardware,
so increasing the constants meant that we were reading and writing
unintended parts of the register set.
This patch changes ISAPNP to use the correct register set sizes (the
same values we used prior to 2.6.24).

a different device (e.g. from eth) and has its own pair of queue

ifb; yet there are possible situations, when this order could be
dangerous; lockdep should warn in such a case.) (With suggestions by

This hasn't struck until eaa0ff15c3 ("fix !
versus & precedence in various places") surrounded the expression with braces,
so that the intended behavior was inverted. That caused 'pixel waste' - the
same line of multi-colored pixels repeated over the whole screen - during

by introducing an event filter, which is removed here, to make
events, we are depending on, happen again.
Fix this by removing the event filter. It's pretty much broken at the
moment, since a user can't set it (the attribute being read only). A
proper fix will be to make the event discriminator distinguish between
AN and Polled media change events.

Now that we handle all the special commands using REQ_TYPE_ATA_TASKFILE
rather than using the old REQ_TYPE_ATA_CMD model, we need to also
emulate the lack of full taskfile data that comes with the old command
model (ie when commands are generated with the HDIO_DRIVE_CMD ioctl
rather than using the HDIO_DRIVE_TASK[FILE] ioctls).
In particular, this means that we should handle command completion the
more relaxed way that the old drive_cmd_intr() code did. It allows
commands to finish early even if they don't use up all the data that we
thought we had for them.
This fixes a regression seen by Anders Eriksson where some SMART
commands sent by smartd would cause a boot-time system hang on his
machine because the IDE command handling code didn't realize that the
command had completed.
