* [SPARC64]: Consolidate MSI support code.David S. Miller2007-10-14
| | | | | | | | | | | | | | | | This also makes us use the MSI queues correctly. Each MSI queue is serviced by a normal sun4u/sun4v INO interrupt handler. This handler runs the MSI queue and dispatches the virtual interrupts indicated by arriving MSIs in that MSI queue. All of the common logic is placed in pci_msi.c, with callbacks to handle the PCI controller specific aspects of the operations. This common infrastructure will make it much easier to add MSG support.

* [SPARC/64]: Move of_platform_driver initialisations: arch/sparc{,64}.Stephen Rothwell2007-10-14
| | | | | | | | We no longer initialise the name field of the of_platform_driver, but use the name field of the embedded device_driver's name field instead. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Fix bugs in SYSV IPC handling in 64-bit processes.David S. Miller2007-10-14
| | | | | | | | | | | | | | | | | Thanks to Tom Callaway for the excellent bug report and test case. sys_ipc() has several problems, most to due with semaphore call handling: 1) 'err' return should be a 'long' 2) "union semun" is passed in a register on 64-bit compared to 32-bit which provides it on the stack and therefore by reference 3) Second and third arguments to SEMCTL are swapped compared to 32-bit.

* [SPARC/64]: Prepare to remove of_platform_driver name.Stephen Rothwell2007-10-14
| | | | | | | | | | | | | The name field of of_platform_driver is just copied into the included device_driver. By not overriding an already initialised device_driver name, we can convert the drivers over time to stop using the of_platform_driver name. Also we were not copying the owner field from of_platform_driver, so do the same with it. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC32]: Add irqflags.h to sparc32 and use it from generic code.Robert Reif2007-10-14
| | | | | | | | | | | | | | | | | | | Added asm-sparc/irqflags.h and moved irq related code from system.h to it. Renamed local_irq functions to raw_local_irq in irq.c. Modified system.h to include linux/irqflags.h which includes asm/irqflags.h. Added TRACE_IRQFLAGS_SUPPORT to Kconfig.debug. This is the first step in adding IRQ-flags state tracing as outlined in Documentation/irqflags-tracing.txt. These changes should be harmless because they just move things around and rename them. The next step is making the lowlevel entry code modifications which to be honest are beyond my capabilities at this point. Boot tested on an ss20 running an SMP kernel.

* [SPARC64]: beautify vmlinux.ldsSam Ravnborg2007-10-14
| | | | | | | | | | | | | Apply a consistent format to vmlinux.lds. The file is now to some degree readable. In addition move several labels inside the braces such that they reflect the actual start address of a section. Without this the label would not reflect if ld added alignment.

| | | | | | | | | | | | | | | | | | | | | | Commit 3d73c288 ("mlx4_core: Fix section mismatches") introduced a stupid bug in device init: when some of mlx4_init_one() was split off into __mlx4_init_one(), the call from the main mlx4_init_one() function was back to mlx4_init_one() rather than to __mlx4_init_one(), which leads to an obvious infinite loop if the function is every called.

* | i2c-nforce2: Abort the transaction on errorOleg Ryjkov2007-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch is to add an abort function that will bring back the MCP51/55 controller if it was blocked by a block-read operation, in particular. (When a slave sends a wrong byte count on a byte read, the host gets locked up). I've only tested it on an MCP51 and MCP55. However, I'm almost certain it will also work on MCP65, I just did not have the board to test it on. Thus for now the abort function will only be called if an MCP51/55 was detected.

* | i2c-nforce2: Move status checking to a separate functionOleg Ryjkov2007-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the first part of the patch that adds a function to reset the nvidia MCP51/55 i2c controller, if something bad happens to it (e.g. a slave sends a wrong byte count during a block transaction). This patch just adds nforce2_check_status function. It was originally written by Hans-Frieder Vogt. The reason that I'm the one sending it is: - I relied on it for the second part of the patch, - It makes the driver code cleaner/better.

* | i2c-au1550: Fix a misused register problemChris David2007-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a "mis-used register" problem on the AMD MIPS Alchemy au1550 I2C interface. In summary, the programmable serial controller seems to hang the kernel when I send a single 'address' byte on the I2C bus. The patch essentially uses the PSC_SMBSTAT register's TE (transmit FIFO empty) bit to check when the transmit FIFO is empty, instead of using the PSC_SMBEVNT register's TU (transmit underflow) bit. Using the TE bit fixed the hang problem. Signed-off-by: Chris David <cd@chrisdavid.com> Acked-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Jean Delvare <khali@linux-fr.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes: - An effectively unused hook: i2c_algorithm.algo_control. - The i2c_control() call, used only by i2c-dev to call that unused hook or set two barely supported adapter params. (That param setting moves into i2c-dev.c ... still iffy due to lack of locking, but no other changes.) As shown by diffstat, this is a net code shrink.

| | | | | | | | | | | | | | | | | | | | | | | | The I2C_M_RECV_LEN calling convention for i2c_mesg.flags involves playing games with reported buffer lengths.
