2006-06-22[PATCH] Driver core: fix locking issues with the devices that are attached ↵Greg Kroah-Hartman

2006-06-22[PATCH] USB: get USB suspend to work againGreg Kroah-Hartman
Yeah, it's a hack, but it is only temporary until Alan's patches reworking this area make it in. We really should not care what devices below us are doing, especially when we do not really know what type of devices they are. This patch relies on the fact that the endpoint devices do not have a driver assigned to us. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2006-06-22[PATCH] myri10ge - drop workaround pci_save_state() disabling MSI Brice Goglin
We don't need to restore the state right after saving it for later recovery since commit 99dc804d9bcc2c53f4c20c291bf4e185312a1a0c (PCI: disable msi mode in pci_disable_device) now prevents pci_save_state() from disabling MSI.

2006-06-22[PATCH] vgacon: make VGA_MAP_MEM take size, remove extra useBjorn Helgaas
VGA_MAP_MEM translates to ioremap() on some architectures. It makes sense to do this to vga_vram_base, because we're going to access memory between vga_vram_base and vga_vram_end. But it doesn't really make sense to map starting at vga_vram_end, because we aren't going to access memory starting there. On ia64, which always has to be different, ioremapping vga_vram_end gives you something completely incompatible with ioremapped vga_vram_start, so vga_vram_size ends up being nonsense. As a bonus, we often know the size up front, so we can use ioremap() correctly, rather than giving it a zero size. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Cc: "Antonino A.

2006-06-22[PATCH] w1: Added default generic read/write operations.Evgeniy Polyakov
Special file in each w1 slave device's directory called "rw" is created each time new slave and no appropriate w1 family is registered. "rw" file supports read and write operations, which allows to perform almost any kind of operations. Each logical operation is a transaction in nature, which can contain several (two or one) low-level operations. Let's see how one can read EEPROM context: 1. one must write control buffer, i.e. buffer containing command byte and two byte address. At this step bus is reset and appropriate device is selected using either W1_SKIP_ROM or W1_MATCH_ROM command. Then provided control buffer is being written to the wire. 2. reading. This will issue reading eeprom response. It is possible that between 1. and 2. w1 master thread will reset bus for searching and slave device will be even removed, but in this case 0xff will be read, since no device was selected.
