2008-02-07Driver core: Revert "Fix Firmware class name collision"Michael E Brown
This reverts commit 109f0e93b6b728f03c1eb4af02bc25d71b646c59. The original patch breaks BIOS updates on all Dell machines. The path to the firmware file for the dell_rbu driver changes, which breaks all of the userspace tools which rely on it. Note that this patch re-introduces a problem with i2c name collision that was previously fixed by this patch.

2008-02-07dz.c: Resource managementMaciej W. Rozycki
This is a set of changes to implement proper resource management in the driver, including iomem space reservation and operating on physical addresses ioremap()ped appropriately using accessory functions rather than unportable direct assignments. Some adjustments to code are made to reflect the architecture of the interface, which is a centrally controlled multiport (or, as referred to from DEC documentation, a serial line multiplexer, going up to 8 lines originally) rather than a bundle of separate ports. Types are changed, where applicable, to specify the width of hardware registers explicitly. The interrupt handler is now managed in the ->startup() and ->shutdown() calls for consistency with other drivers and also in preparation to handle the handover from the initial firmware-based console gracefully.

2008-02-07dz.c: Use a helper to cast from "struct uart_port *"Maciej W. Rozycki
Replace all casts from "struct uart_port *" to "struct dz_port *" with a construct based on container_of(). This makes the conversion work irrespective of where the former struct is located within the latter. By popular request I have implemented it as an inline function rather than a macro this time.

2008-02-07dz: clean up and improve the setup of termios settingsMaciej W. Rozycki
A set of changes to the way termios settings are propagated to the serial port hardware. The DZ11 only supports a selection of fixed baud settings, so some requests may not be fulfilled. Keep the old setting in such a case and failing that resort to 9600bps. Also add a missing update of the transmit timeout. And remove the explicit encoding of the line selected from writes to the Line Parameters Register as it has been preencoded by the ->set_termios() call already. Finally, remove a duplicate macro for the Receiver Enable bit. Signed-off-by: Maciej W.

2008-02-07dz: always check if it is safe to console_putchar()Maciej W. Rozycki
Polled transmission is tricky enough with the DZ11 design. While "loop" is set to a high value, conceptually you are not allowed to transmit without checking whether the device offers the right transmission line (yes, it is the device that selects the line -- the driver has no control over it other than disabling the transmitter offered if it is the wrong one), so the loop has to be run at least once. Well, the '1977 or PDP11 view of how serial lines should be handled... Except that the serial interface used to be quite an impressive board back then rather than chip. Signed-off-by: Maciej W.

2008-02-07drivers/edac: pci: broken parity regressionBryan Boatright
Using the EDAC code in kernel.org kernel version 2.6.23.8 I am seeing the following problem: In the kernel there is a pci device attribute located in sysfs that is checked by the EDAC PCI scanning code. If that attribute is set, PCI parity/error scannining is skipped for that device. The attribute is: broken_parity_status as is located in /sys/devices/pci<XXX>/0000:XX:YY.Z directorys for PCI devices. I don't think this check was actually implemented. I have a misbehaved card that reports a parity error every 1000 ms: Nov 25 07:28:43 beta kernel: EDAC PCI: Master Data Parity Error on 0000:05:01.0 Nov 25 07:28:44 beta kernel: EDAC PCI: Master Data Parity Error on 0000:05:01.0 Nov 25 07:28:45 beta kernel: EDAC PCI: Master Data Parity Error on 0000:05:01.0 Setting that card's broken_parity_status bit did not mask the error: echo "1" > /sys/bus/pci/devices/0000:05:01.0/broken_parity_status I looked through the EDAC code and did not readily see any reference to broken_parity_status at all (which makes sense based on the behavior I am seeing). I applied the following patch as a proof-of-concept and now EDAC's PCI parity error reporting behaves as documented: bryan Good regression find, bryan. It used to work. sigh. I added more logic to your patch, for more coverage of the error.
