I'm attaching a patch to fix status when using Siemens X65 mobile. This mobile use first byte instead of normal UART_STATE byte.

It's possible to unplug usb device and do tiocmset() and tiocmget() without valid interface in pl2303 module. The patch below check this and return -ENODEV if interface was removed. From: Flavio Leitner <fbl@conectiva.com.br> Signed-off-by: -

In response to complaints about excessive latency in the uhci-hcd driver I'm planning to convert it to a top-half/bottom-half design. It turns out that to do this, the USB API has to be modified slightly since the driver will not be able to meet one of the guarantees in the current API. This patch changes some kerneldoc, specifying the weaker guarantee. Signed-off-by:

This adds a quirk to the OHCI driver that lets it work with an old Compaq implementation. It also removes some needless strings from the non-debug version of the driver. Signed-off-by:

This patch changes the delay for the US_FL_GO_SLOW patch from 110us to 125. Some delays need this extra delay includign Jan De Luyck's drive which spawned the original increase from 110 to 110us. 125 is a microframe, so this delay seems to make sense more than just be a random delay (thanks to David Brownell for pointing that out after my original patch).

I am sorry that the last patch about 32 bit compat ioctl on 64 bit kernel actually breaks the usbdevfs. That is on the current BK tree. I am retarded. Here is the patch to fix it. Tested with USB hard disk and webcam in both 32bit compatible mode and native 64bit mode. Again, sorry about that. From: Christopher Li <chrisl@vmware.com> Signed-off-by: -

This reverts a recent change to usb_set_interface(). The change worked around a quirk in certain devices, but doing this in usbcore creates needless regressions for other devices. More appropriate fixes won't put such handling in usbcore. Basically it's tricky to do a full software reset of USB device state, since the devices don't all act the same. This adds a note to the kerneldoc for the usb_reset_configuration() call to highlight the quirk this was working around: endpoint data toggles not being reset. Signed-off-by:

This patch includes minor "sparse -Wbitwise" updates for the PCI based HCDs. Almost all of them involve just changing the second parameter of the suspend() method to a pm_message_t ... the others relate to how the EHCI code walks in-memory data structures. (There's a minor bug fixed there too ... affecting the big-endian sysfs async schedule dump.) Signed-off-by:

This is the first of a few installments of PM API updates to match the recent switch to "pm_message_t". This installment primarily affects USB device drivers (for USB interfaces), and it changes the handful of drivers which currently implement suspend methods: - <linux/usb.h> and usbcore, signature change - Some drivers only changed the signature, net effect this just shuts up "sparse -Wbitwise": * hid-core * stir4200 - Two network drivers did that, and also grew slightly more featureful suspend code ... they now properly shut down their activities. (As should stir4200...) * pegasus * usbnet Note that the Wake-On-Lan (WOL) support in pegasus doesn't yet work; looks to me like it's missing a request to turn it on, vs just configuring it. The ASIX code in usbnet also has WOL hooks that are ready to use; untested. Signed-off-by: -

This has a variety of updates to the shared suspend/resume code for PCI based USB host controllers. - Cope with pm_message_t replacing the target system state. This is actually a loss of functionality; PCI D1 and D2 states will no longer be used, and it's no longer knowable that D3cold is on the way so power will be lost. - Most importantly, some of the resume paths are reworked and cleaned up. They're now an exact mirror of suspend paths, and more care is taken to ensure the hardware is reactivated before the hardware re-enables interrupts. Plus comment and diagnostic cleanups; there are some nasty cases here especially combined with swsusp, now they're somewhat commented. Signed-off-by: -

Here's a tiny patch to add support for the Tapwave Zodiac (for 2.6.11.6). I've been meaning to send it in for a while but kept upgrading my kernel and losing the changes :-) I own the device and it works fine with the latest pilot-link beta.

Like Alpha, sparc64's struct stat was defined before we had the nanosecond et al. fields added. So like Alpha I have to cons up a struct stat64 to get this stuff. I'll work on the glibc bits soon. Also, we were forgetting to fill in the nanosecond fields in the sparc compat stat64 syscalls. Signed-off-by:

This adds 32-bit compatibility for mounting an NFSv4 mount on a 64-bit kernel (such as happens with PPC64). The problem is that the mount data for the NFS4 mount process includes auxilliary data pointers, probably because the NFS4 mount data may conceivably exceed PAGE_SIZE in size - thus breaking against the hard limit imposed by sys_mount().

This fixes a deadlock on the dcache lock detected during testing at IBM by moving the logging of the current executable information from the SELinux avc_audit function to audit_log_exit (via an audit_log_task_info helper) for processing upon syscall exit. For consistency, the patch also removes the logging of other task-related information from avc_audit, deferring handling to audit_log_exit instead. This allows simplification of the avc_audit code, allows the exe information to be obtained more reliably, always includes the comm information (useful for scripts), and avoids including bogus task information for checks performed from irq or softirq.

We were flushing the D-cache excessively for ptrace() processing and this makes debugging threads so slow as to be totally unusable. All process page accesses via ptrace() go via access_process_vm(). This routine, for each process page, uses get_user_pages(). That in turn does a flush_dcache_page() on the child pages before we copy in/out the ptrace request data. Therefore, all we need to do after the data movement is: 1) Flush the D-cache pages if the kernel maps the page to a different color than userspace does. 2) If we wrote to the page, we need to flush the I-cache on older cpus. Previously we just flushed the entire cache at the end of a ptrace() request, and that was beyond stupid. Signed-off-by:

SunOS aparently had this weird PTRACE_CONT semantic which we copied. If the addr argument is something other than 1, it sets the process program counter to whatever that value is. This is different from every other Linux architecture, which don't do anything with the addr and data args. This difference in particular breaks the Linux native GDB support for fork and vfork tracing on sparc and sparc64. There is no interest in running SunOS binaries using this weird PTRACE_CONT behavior, so just delete it so we behave like other platforms do. Signed-off-by:

This case actually can get exercised a lot during an ELF coredump of a process which contains a lot of non-COW'd anonymous pages. GDB has this test case which in partiaular creates near terabyte process full of ZERO_PAGEes. It takes forever to just walk through the page tables because of all of these spurious cache flushes on sparc64. With this change it takes only a second or so. Signed-off-by:

This reverts a fs/char_dev.c patch that was merged into BK on March 3. The problem is that it breaks things ... __register_chrdev_region() has a block of code, commented "temporary" for over two years now, which fails rudely during PCMCIA initialization or other register_chrdev() calls, because it doesn't "degrade to linked list". This keeps whole subsystems from working. A real fix to that "temporary" code should be possible, using some better scheme to allocate major numbers, but it's not something I want to spend time on just now. Signed-off-by:
