This patch (as737b) does a very small cleanup of core/sysfs.c by adding the configuration_string attribute file to the existing attribute group instead of treating it separately. It doesn't need this separate treatment because unlike the other device string attributes, it changes along with the active configuration. The patch also fixes a simple typo (which, oddly enough, doesn't seem to bother the compiler). Signed-off-by:

kfree() handles NULL arguments which is handy in error handling paths as one does need to insert bunch of ifs. How about making usb_buffer_free() do the same? Signed-off-by:

Add (dummy?) support for TIOCGSERIAL and TIOCSSERIAL ioctl calls to the USB serial driver file `ark3116.c'. This is sufficient for me to run wvdial successfully, receive my email, and do webbrowsing with firefox. On the other hand, running the cvs program to update archives seems not to work, and the traceroute command sometimes says send failed: No buffer space available Looks like a buffering problem... My knowledge of serial device drivers is zero, so I can't fix this -- I just did a cut'n'paste from other USB serial drivers... Signed-off-by:

This updates the PXA 25x UDC board-independent infrastructure for VBUS sensing and the D+ pullup. The original code evolved from rather bizarre support on Intel's "Lubbock" reference hardware, so that on more sensible hardware it doesn't work as well as it could/should. The change is just to teach the UDC driver how to use built-in PXA GPIO pins directly. This reduces the amount of board-specfic object code needed, and enables the use of a VBUS sensing IRQ on boards (like Gumstix) that have one. With VBUS sensing, the UDC is unclocked until a host is actually connected. Signed-off-by:

inlined is the patch that adds basic support for USB OHCI controller support for PNX4008 Philips PNX4008 ARM board. Due to HW design, it depends on I2C driver for PNX4008 which I've recetnly posted to LKML and i2c at lm-sensors. Signed-off-by:

With the newer Samsung S3C2412 and S3C2413 SoC devices, the 48MHz USB clock has been given an individual gate into the USB OHCI and gadget blocks. This clock is called usb-bus-clock, and we need to replace the old use of the USB PLL (upll) directly with the new usb-bus-host. The S3C2410 clock driver has been updated already to provide a virtual clock which is a child of the UPLL to maintain compatibility. The S3C2412 clock driver correctly enables the PLL when either usb-bus clock is active. Signed-off-by:

This teaches OHCI to use the root hub status change (RHSC) IRQ, bypassing root hub timers most of the time and switching over to the "new" root hub polling scheme. It's complicated by the fact that implementations of OHCI trigger and ack that IRQ differently (the spec is vague there). Avoiding root hub timers helps mechanisms like "dynamic tick" leave the CPU in lowpower modes for longer intervals. Signed-off-by:

This patch (as781) adds an entry to unusual_devs.h for the Lacie DVD+-RW drive. Apparently its USB interface has requirements similar to the Genesys Logic interface; it doesn't like data to be sent too soon after a command. This fixes Bugzilla #6817. Signed-off-by:

Ingo Oeser pointed out that because current expands to an inline function it is more space efficient and somewhat faster to simply keep a cached copy of current in another variable. This patch implements that for the de_thread function. (akpm: saves nearly 100 bytes of text on x86) Signed-off-by:

With the patches flying between Oleg and myself somehow this temporary debug code got left in pid.c. It was never intended to make it to the stable kernel. Signed-off-by:
-
Eric W. Biederman authored
In de_thread we move pids from one process to another, a rather ugly case. The function transfer_pid makes it clear what we are doing, and makes the action atomic. This is useful we ever want to atomically traverse the process group and session lists, in a rcu safe manner. Even if the atomic properties this change should be a win as transfer_pid should be less code to execute than executing both attach_pid and detach_pid, and this should make de_thread slightly smaller as only a single function call needs to be emitted. The only downside is that the code might be slower to execute as the odds are against transfer_pid being in cache. Signed-off-by:

Add modalias attribute support for the almost forgotten now EISA bus and (at least some) EISA-aware modules. The modalias entry looks like (for an 3c509 NIC): eisa:sTCM5093 and the in-module alias like: eisa:sTCM5093* The patch moves struct eisa_device_id declaration from include/linux/eisa.h to include/linux/mod_devicetable.h (so that the former now #includes the latter), adds proper MODULE_DEVICE_TABLE(eisa, ...) statements for all drivers with EISA IDs I found (some drivers already have that DEVICE_TABLE declared), and adds recognision of __mod_eisa_device_table to scripts/mod/file2alias.c so that proper modules.alias will be generated. There's no support for /lib/modules/$kver/modules.eisamap, as it's not used by any existing tools, and because with in-kernel modalias mechanism those maps are obsolete anyway. The rationale for this patch is: a) to make EISA bus to act as other busses with modalias support, to unify driver loading b) to foget about EISA finally - with this patch, kernel (who still supports EISA) will be the only one who knows how to choose the necessary drivers for this bus ;) [akpm@osdl.org: fix the kbuild bit] Signed-off-by:Michael Tokarev <mjt@tls.msk.ru> Cc: Rusty Russell <rusty@rustcorp.com.au> Cc: Randy Dunlap <rdunlap@xenotime.net> Acked-the-net-bits-by:

IA32 manual says if micorcode update's size is 0, then the size is default size (2048 bytes). But this doesn't suggest all microcode update's size should be above 2048 bytes to me. We actually had a microcode update whose size is 1024 bytes. The patch just removed the check. Signed-off-by:

Add sysfs support. Currently each CPU has three microcode related attributes. One is 'version' which shows current ucode version of CPU. Tools can use the attribute do validation or show CPU ucode status. one is 'reload' which allows manually reloading ucode. Another is 'processor_flags', which exports processor flags, so we can write tools to check if CPU has latest ucode. Also add suspend/resume and CPU hotplug support.

Using request_firmware to pull ucode from userspace, so we don't need the application 'microcode_ctl' to assist. We name each ucode file according to CPU's info as intel-ucode/family-model-stepping. In this way we could split ucode file as small one. This has a lot of advantages such as selectively update and validate microcode for specific models, better manage microcode file, easily write tools for administerators and so on. with the changes, we should put all intel-ucode/xx-xx-xx microcode files into the firmware dir (I had a tool to split previous big data file into small one and later we will release new style data file). The init script should be changed to just loading the driver without unloading Signed-off-by:
