Introduce a function to register failure in an inode construction path. This includes marking the inode under construction as bad, unlocking it and releasing it. Signed-off-by:

Add an ERR_CAST() function to complement ERR_PTR and co. for the purposes of casting an error entyped as one pointer type to an error of another pointer type whilst making it explicit as to what is going on. This provides a replacement for the ERR_PTR(PTR_ERR(p)) construct. Signed-off-by:

This patch fixes the configuration dependencies in the vmcoreinfo data. i386's "node_data" is defined in arch/x86/mm/discontig_32.c, and x86_64's one is defined in arch/x86/mm/numa_64.c. They depend on CONFIG_NUMA: arch/x86/mm/Makefile_32:7 obj-$(CONFIG_NUMA) += discontig_32.o arch/x86/mm/Makefile_64:7 obj-$(CONFIG_NUMA) += numa_64.o ia64's "pgdat_list" is defined in arch/ia64/mm/discontig.c, and it depends on CONFIG_DISCONTIGMEM and CONFIG_SPARSEMEM: arch/ia64/mm/Makefile:9-10 obj-$(CONFIG_DISCONTIGMEM) += discontig.o obj-$(CONFIG_SPARSEMEM) += discontig.o ia64's "node_memblk" is defined in arch/ia64/mm/numa.c, and it depends on CONFIG_NUMA: arch/ia64/mm/Makefile:8 obj-$(CONFIG_NUMA) += numa.o Signed-off-by:Ken'ichi Ohmichi <oomichi@mxs.nes.nec.co.jp> Acked-by:

This patchset is for the vmcoreinfo data. The vmcoreinfo data has the minimum debugging information only for dump filtering. makedumpfile (dump filtering command) gets it to distinguish unnecessary pages, and makedumpfile creates a small dumpfile. This patch: VMCOREINFO_SIZE() should be renamed VMCOREINFO_STRUCT_SIZE() since it's always returning the size of the struct with a given name. This change would allow VMCOREINFO_TYPEDEF_SIZE() to simply become VMCOREINFO_SIZE() since it need not be used exclusively for typedefs.

This patchset adds a flags variable to reserve_bootmem() and uses the BOOTMEM_EXCLUSIVE flag in crashkernel reservation code to detect collisions between crashkernel area and already used memory. This patch: Change the reserve_bootmem() function to accept a new flag BOOTMEM_EXCLUSIVE. If that flag is set, the function returns with -EBUSY if the memory already has been reserved in the past. This is to avoid conflicts. Because that code runs before SMP initialisation, there's no race condition inside reserve_bootmem_core().

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.

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.

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:

Reformat the Kconfig entries and update descriptions for accuracy. Select the driver by default for configurations of interest. For the curious: 32BIT means only 32-bit DECstations support the device, not that the driver is not 64-bit clean; I have not checked that either though. Signed-off-by:

Well, panic() is a little bit undue if request_irq() fails; there is probably no need to justify it any further. Handle the case gracefully, by unregistering the driver. Signed-off-by:

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:

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. Doug T Signed-off-by:Bryan Boatright <b1@omega71.com> Signed-off-by:

Adds driver for the Cell memory controller when used without a Hypervisor such as on the IBM Cell blades. There might still be some improvements to do to this such as finding if it's possible to properly obtain more details about the address of the error but it's good enough already to report CE counts which is our main priority at the moment.

This is a patch for the Compaq ASIC3 multi function chip, found in many PDAs (iPAQs, HTCs...). It is a simplified version of Paul Sokolovsky's first proposal [1]. With this code, it is basically a GPIO and IRQ expander. My plan is to add more features once this patch gets reviewed and accepted. [1] http://lkml.org/lkml/2007/5/1/46Signed-off-by:
