2008-02-05is_vmalloc_addr(): Check if an address is within the vmalloc boundariesChristoph Lameter
Checking if an address is a vmalloc address is done in a couple of places. Define a common version in mm.h and replace the other checks. Again the include structures suck. The definition of VMALLOC_START and VMALLOC_END is not available in vmalloc.h since highmem.c cannot be included there.

2008-02-05gpiolib: pca9539 i2c gpio expander supporteric miao
This adds a new-style I2C driver with basic support for the sixteen bit PCA9539 GPIO expanders. These chips have multiple registers, push-pull output drivers, and (not supported in this patch) pin change interrupts. Board-specific code must provide "pca9539_platform_data" with each chip's "i2c_board_info". That provides the GPIO numbers to be used by that chip, and callbacks for board-specific setup/teardown logic. Derived from drivers/i2c/chips/pca9539.c (which has no current known users). This is faster and simpler; it uses 16-bit register access, and cache the OUTPUT and DIRECTION registers for fast access Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Acked-by: Jean Delvare <khali@linux-fr.org> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Haavard Skinnemoen <hskinnemoen@atmel.com> Cc: Philipp Zabel <philipp.zabel@gmail.com> Cc: Russell King <rmk@arm.linux.org.uk> Cc: Ben Gardner <bgardner@wabtec.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-02-05gpiolib: pcf857x i2c gpio expander supportDavid Brownell
This is a new-style I2C driver for most common 8 and 16 bit I2C based "quasi-bidirectional" GPIO expanders: pcf8574 or pcf8575, and several compatible models (mostly faster, supporting I2C at up to 1 MHz). The driver exposes the GPIO signals using the platform-neutral GPIO programming interface, so they are easily accessed by other kernel code. The lack of such a flexible kernel API has been a big factor in the proliferation of board-specific drivers for these chips... stuff that rarely makes it upstream since it's so ugly. This driver will let such boards use standard calls. Since it's a new-style driver, these devices must be configured as part of board-specific init. That eliminates the need for error-prone manual configuration of module parameters, and makes compatibility with legacy drivers (pcf8574.c, pc8575.c) for these chips easier (there's a clear either/or disjunction).

2008-02-05gpiolib: add gpio provider infrastructureDavid Brownell
Provide new implementation infrastructure that platforms may choose to use when implementing the GPIO programming interface. Platforms can update their GPIO support to use this. In many cases the incremental cost to access a non-inlined GPIO should be less than a dozen instructions, with the memory cost being about a page (total) of extra data and code. The upside is: * Providing two features which were "want to have (but OK to defer)" when GPIO interfaces were first discussed in November 2006: - A "struct gpio_chip" to plug in GPIOs that aren't directly supported by SOC platforms, but come from FPGAs or other multifunction devices using conventional device registers (like UCB-1x00 or SM501 GPIOs, and southbridges in PCs with more open specs than usual). - Full support for message-based GPIO expanders, where registers are accessed through sleeping I/O calls. Previous support for these "cansleep" calls was just stubs. (One example: the widely used pcf8574 I2C chips, with 8 GPIOs each.) * Including a non-stub implementation of the gpio_{request,free}() calls, making those calls much more useful. The diagnostic labels are also recorded given DEBUG_FS, so /sys/kernel/debug/gpio can show a snapshot of all GPIOs known to this infrastructure. The driver programming interfaces introduced in 2.6.21 do not change at all; this infrastructure is entirely below those covers.

2008-02-05gpiolib: add drivers/gpio directoryDavid Brownell
Add an empty drivers/gpio directory for gpiolib infrastructure and GPIO expanders. It will be populated by later patches. This won't be the only place to hold such gpio_chip code. Many external chips add a few GPIOs as secondary functionality (such as MFD drivers) and platform code frequently needs to closely integrate GPIO and IRQ support. This is placed *early* in the build/link sequence since it's common for other drivers to depend on GPIOs to do their work, so they must be initialized early in the device_initcall() sequence.

2008-02-05iommu sg merging: call dma_set_seg_boundary in __scsi_alloc_queue()FUJITA Tomonori
This is a one-line patch to add the following to __scsi_alloc_queue(): dma_set_seg_boundary(dev, shost->dma_boundary); This is the simplest approach but the result looks odd, __scsi_alloc_queue() does: blk_queue_segment_boundary(q, shost->dma_boundary); dma_set_seg_boundary(dev, shost->dma_boundary); blk_queue_max_segment_size(q, dma_get_max_seg_size(dev)); I think that it would be better to set up segment boundary in the same way as we did for the maximum segment size. That is, removing shost->dma_boundary and LLDs call pci_set_dma_seg_boundary (or its friends). Then __scsi_alloc_queue() can set up both limits in the same way: blk_queue_segment_boundary(q, dma_get_seg_boundary(dev)); blk_queue_max_segment_size(q, dma_get_max_seg_size(dev)); killing dma_boundary in scsi_host_template needs a large patch for libata (dma_boundary is used by only libata and sym53c8xx). I'll send a patch to do that if it is acceptable. James and Jeff?

2008-02-05serial: MPSC: set baudrate when BRG divider is set.Mark A. Greer
The clock to generate the desired baudrate with the MPSC is first divided by the Baud Rate Generator (BRG) and then by the MPSC itself. So, when the BRG divider is changed, the MPSC divider must also be changed to generate the correct baudrate. During MPSC initialization, the BRG divider is changed but the MPSC divider isn't changed until much later. This results in some printk's coming out garbled. To fix that, set the MPSC divider at the same time that the BRG divider is changed. Signed-off-by: Mark A.

2008-02-05serial: avoid stalling suspend if serial port won't drainRussell King
Some ports seem to be unable to drain their transmitters on shut down. Such a problem can occur if the port is programmed for hardware imposed flow control, characters are in the FIFO but the CTS signal is inactive. Normally, this isn't a problem because most places where we wait for the transmitter to drain have a time-out. However, there is no timeout in the suspend path. Give a port 30ms to drain; this is an arbitary value chosen to avoid long delays if there are many such ports in the system, while giving a reasonable chance for a single port to drain. Should a port not drain within this timeout, issue a warning.

2008-02-05serial: avoid waking up closed serial ports on resumeRussell King
When we boot, serial ports remain in low power mode until they're used either by userspace or for the kernel console. However, if you suspend the system, and then resume, all serial ports will be taken out of low power mode. This is bad news for embedded devices where this can mean higher power consumption. Only bring a serial port out of low power mode if the port is being used as the kernel console, or is in use by userspace.

2008-02-05pcmcia: convert some internal-only ioaddr_t to unsigned intOlof Johansson
Convert the io_req_t members to unsigned int, to allow use on machines with more than 16 bits worth of IO ports (i.e. secondary busses on ppc64, etc). There was only a couple of places in drivers where a change was needed. I left printk formats alone (there are lots of %04x-style formats in there), mostly to not change the format on the platforms that only have 16-bit io addresses, but also because the padding doesn't really add all that much value most of the time. I found only one sprintf of an address, and upsized the string accordingly (I doubt anyone will have anywhere near INT_MAX as irq value, but at least there's room for it now).

2008-02-04vm audit: add VM_DONTEXPAND to mmap for drivers that need itNick Piggin
Drivers that register a ->fault handler, but do not range-check the offset argument, must set VM_DONTEXPAND in the vm_flags in order to prevent an expanding mremap from overflowing the resource. I've audited the tree and attempted to fix these problems (usually by adding VM_DONTEXPAND where it is not obvious).

2008-02-04[ARM] 4660/3: at91: allow selecting UART for early kernel messagesGuennadi Liakhovetski
Currently early kernel messages, i.e., those from uncompression, go to the debugging UART. And if it is enabled in the platform configuration, but not initialized by the bootloader, the machine hangs, waiting for UART status change. Besides, having those messages on another UART - typically the console UART - may be preferrable. This patch allows selecting the UART in kernel configuration.

2008-02-04virtio: balloon driverRusty Russell
After discussions with Anthony Liguori, it seems that the virtio balloon can be made even simpler. Here's my attempt. The device configuration tells the driver how much memory it should take from the guest (ie. balloon size). The guest feeds the page numbers it has taken via one virtqueue. A second virtqueue feeds the page numbers the driver wants back: if the device has the VIRTIO_BALLOON_F_MUST_TELL_HOST bit, then this queue is compulsory, otherwise it's advisory (and the guest can simply fault the pages back in). This driver can be enhanced later to deflate the balloon via a shrinker, oom callback or we could even go for a complete set of in-guest regulators.
