Use the driver data structure as the main device reference, instead of the i2c client. It makes the driver a bit smaller, and makes more sense as this is an hybrid driver, supporting both I2C and ISA devices. Signed-off-by: NJean Delvare <khali@linux-fr.org>

Some hardware monitoring drivers create the VID/VRM interface files conditionally depending on the chip model or configuration. We should only call vid_which_vrm() when we are actually going to create the files. Not only it is more logical and efficient that way, but it also prevents printing unnecessary warnings such as the one reported here: http://lists.lm-sensors.org/pipermail/lm-sensors/2007-February/018954.htmlSigned-off-by: NJean Delvare <khali@linux-fr.org>

My understanding of the resource management in the Linux 2.6 device driver model is that the devices should declare their resources, and then when a driver attaches to a device, it should request the resources it will be using, so as to mark them busy. This is how the PCI and PNP subsystems work, you can clearly see the two levels of resources (declaration and request) in /proc/ioports for these devices. So I believe that our platform hardware monitoring drivers should follow the same logic. At the moment, we only declare the resources but we do not request them. This patch adds the I/O region request and release calls. Signed-off-by: NJean Delvare <khali@linux-fr.org> Acked-by: NJuerg Haefliger <juergh@gmail.com>

由 Christoph Lameter 提交于
I have never seen a use of SLAB_DEBUG_INITIAL. It is only supported by SLAB. I think its purpose was to have a callback after an object has been freed to verify that the state is the constructor state again? The callback is performed before each freeing of an object. I would think that it is much easier to check the object state manually before the free. That also places the check near the code object manipulation of the object. Also the SLAB_DEBUG_INITIAL callback is only performed if the kernel was compiled with SLAB debugging on. If there would be code in a constructor handling SLAB_DEBUG_INITIAL then it would have to be conditional on SLAB_DEBUG otherwise it would just be dead code. But there is no such code in the kernel. I think SLUB_DEBUG_INITIAL is too problematic to make real use of, difficult to understand and there are easier ways to accomplish the same effect (i.e. add debug code before kfree). There is a related flag SLAB_CTOR_VERIFY that is frequently checked to be clear in fs inode caches. Remove the pointless checks (they would even be pointless without removeal of SLAB_DEBUG_INITIAL) from the fs constructors. This is the last slab flag that SLUB did not support. Remove the check for unimplemented flags from SLUB.

Architectures that don't support DMA can say so by adding a config NO_DMA to their Kconfig file. This will prevent compilation of some dma specific driver code. Also dma-mapping-broken.h isn't needed anymore on at least s390. This avoids compilation and linking of otherwise dead/broken code. Other architectures that include dma-mapping-broken.h are arm26, h8300, m68k, m68knommu and v850. If these could be converted as well we could get rid of the header file.

Ensure pages are uptodate after returning from read_cache_page, which allows us to cut out most of the filesystem-internal PageUptodate calls. I didn't have a great look down the call chains, but this appears to fixes 7 possible use-before uptodate in hfs, 2 in hfsplus, 1 in jfs, a few in ecryptfs, 1 in jffs2, and a possible cleared data overwritten with readpage in block2mtd. All depending on whether the filler is async and/or can return with a !uptodate page.

由 Dave Jiang 提交于
The MPSC serial driver assumes that interrupt is always on to pick up the DMA transmit ops that aren't submitted while the DMA engine is active. However when irqs are off for a period of time such as operations under kernel crash dump console messages do not show up due to additional DMA ops are being dropped. This makes console writes to process through all the tx DMAs queued up before submitting a new request. Also, the current locking mechanism does not protect the hardware registers and ring buffer when a printk is done during the serial write operations. The additional per port transmit lock provides a finer granular locking and protects registers being clobbered while printks are nested within UART writes.

At present, the serial core always allows setserial in userspace to change the port address, irq and base clock of any serial port. That makes sense for legacy ISA ports, but not for (say) embedded ns16550 compatible serial ports at peculiar addresses. In these cases, the kernel code configuring the ports must know exactly where they are, and their clocking arrangements (which can be unusual on embedded boards). It doesn't make sense for userspace to change these settings. Therefore, this patch defines a UPF_FIXED_PORT flag for the uart_port structure. If this flag is set when the serial port is configured, any attempts to alter the port's type, io address, irq or base clock with setserial are ignored. In addition this patch uses the new flag for on-chip serial ports probed in arch/powerpc/kernel/legacy_serial.c, and for other hard-wired serial ports probed by drivers/serial/of_serial.c.

Serial driver patch for the PMC-Sierra MSP71xx devices. There are three different fixes: 1 Fix for DesignWare APB THRE errata: In brief, this is a non-standard 16550 in that the THRE interrupt will not re-assert itself simply by disabling and re-enabling the THRI bit in the IER, it is only re-enabled if a character is actually sent out. It appears that the "8250-uart-backup-timer.patch" in the "mm" tree also fixes it so we have dropped our initial workaround. This patch now needs to be applied on top of that "mm" patch. 2 Fix for Busy Detect on LCR write: The DesignWare APB UART has a feature which causes a new Busy Detect interrupt to be generated if it's busy when the LCR is written. This fix saves the value of the LCR and rewrites it after clearing the interrupt. 3 Workaround for interrupt/data concurrency issue: The SoC needs to ensure that writes that can cause interrupts to be cleared reach the UART before returning from the ISR. This fix reads a non-destructive register on the UART so the read transaction completion ensures the previously queued write transaction has also completed.

PCI drivers have the new_id file in sysfs which allows new IDs to be added at runtime. The advantage is to avoid re-compilation of a driver that works for a new device, but it's ID table doesn't contain the new device. This mechanism is only meant for testing, after the driver has been tested successfully, the ID should be added in source code so that new revisions of the kernel automatically detect the device. The implementation follows the PCI implementation. The interface is documented in Documentation/pcmcia/driver.txt. Computations should be done in userspace, so the sysfs string contains the raw structure members for matching.
