2013-06-10USB: serial: ports: add minor and port numberGreg Kroah-Hartman24-180/+133
The usb_serial_port structure had the number field, which was the minor number for the port, which almost no one really cared about. They really wanted the number of the port within the device, which you had to subtract from the minor of the parent usb_serial_device structure. To clean this up, provide the real minor number of the port, and the number of the port within the serial device separately, as these numbers might not be related in the future. Bonus is that this cleans up a lot of logic in the drivers, and saves lines overall.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fixes from Steven Rostedt: "This contains 4 fixes. The first two fix the case where full RCU debugging is enabled, enabling function tracing causes a live lock of the system. This is due to the added debug checks in rcu_dereference_raw() that is used by the function tracer. These checks are also traced by the function tracer as well as cause enough overhead to the function tracer to slow down the system enough that the time to finish an interrupt can take longer than when the next interrupt is triggered, causing a live lock from the timer interrupt. Talking this over with Paul McKenney, we came up with a fix that adds a new rcu_dereference_raw_notrace() that does not perform these added checks, and let the function tracer use that. The third commit fixes a failed compile when branch tracing is enabled, due to the conversion of the trace_test_buffer() selftest that the branch trace wasn't converted for. The forth patch fixes a bug caught by the RCU lockdep code where a rcu_read_lock() is performed when rcu is disabled (either going to or from idle, or user space). This happened on the irqsoff tracer as it calls task_uid(). The fix here was to use current_uid() when possible that doesn't use rcu locking. Which luckily, is always used when irqsoff calls this code." * tag 'trace-fixes-v3.10-rc3-v3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Use current_uid() for critical time tracing tracing: Fix bad parameter passed in branch selftest ftrace: Use the rcu _notrace variants for rcu_dereference_raw() and friends rcu: Add _notrace variation of rcu_dereference_raw() and hlist_for_each_entry_rcu()
2013-06-07Revert "ACPI / scan: do not match drivers against objects having scan handlers"Rafael J. Wysocki1-4/+0
Commit 9f29ab11ddbf ("ACPI / scan: do not match drivers against objects having scan handlers") introduced a boot regression on Tony's ia64 HP rx2600. Tony says: "It panics with the message: Kernel panic - not syncing: Unable to find SBA IOMMU: Try a generic or DIG kernel [...] my problem comes from arch/ia64/hp/common/sba_iommu.c where the code in sba_init() says: acpi_bus_register_driver(&acpi_sba_ioc_driver); if (!ioc_list) { but because of this change we never managed to call ioc_init() so ioc_list doesn't get set up, and we die."

into fixes From Shawn Guo, mxs fixes for 3.10: - Since the time we move to MULTI_IRQ_HANDLER, the 0x7f polling for no interrupt in icoll_handle_irq() becomes insane, because 0x7f is an valid interrupt number, the irq of gpio bank 0. That unnecessary polling results in the driver not detecting when irq 0x7f is active which makes the machine effectively dead lock. The fix removes the interrupt poll loop and allows usage of gpio0 interrupt without an infinite loop. * tag 'mxs-fixes-3.10' of git://git.linaro.org/people/shawnguo/linux-2.6: ARM: mxs: icoll: Fix interrupts gpio bank 0 Signed-off-by: Olof Johansson <olof@lixom.net>

2013-06-07ARM: exynos: add debug_ll_io_init() call in exynos_init_io()Doug Anderson1-0/+2
If the early MMU mapping of the UART happens to get booted out of the TLB between the start of paging_init() and when we finally re-add the UART at the very end of s3c_init_cpu(), we'll get a hang at bootup if we've got early_printk enabled. Avoid this hang by calling debug_ll_io_init() early. Without this patch, you can reliably reproduce a hang when early printk is enabled by adding flush_tlb_all() at the start of exynos_init_io(). After this patch the hang goes away. Signed-off-by: Doug Anderson <dianders@chromium.org> Acked-by: Kukjin Kim <kgene.kim@samsung.com> Signed-off-by: Olof Johansson <olof@lixom.net>

2013-06-07ARM: EXYNOS: uncompress - print debug messages if DEBUG_LL is definedTushar Behera1-1/+9
Printing low-level debug messages make an assumption that the specified UART port has been preconfigured by the bootloader. Incorrectly specified UART port results in system getting stalled while printing the message "Uncompressing Linux... done, booting the kernel" This UART port number is specified through S3C_LOWLEVEL_UART_PORT. Since the UART port might different for different board, it is not possible to specify it correctly for every board that use a common defconfig file. Calling this print subroutine only when DEBUG_LL fixes the problem. By disabling DEBUG_LL in default config file, we would be able to boot multiple boards with different default UART ports. With this current approach, we miss the print "Uncompressing Linux... done, booting the kernel." when DEBUG_LL is not defined.

git://git.kernel.org/pub/scm/linux/kernel/git/sarah/xhci into usb-next Sarah writes: xHCI: USB 2.0 Link PM and misc cleanup patches Hi Greg, Here's six patches to be queued for 3.11. The first four add support for a new type of host hardware-managed USB 2.0 Link Power Management. Hosts with BESL support, including Intel Haswell ULT systems, will now be able to have USB 2.0 devices go into the lower power link state (L1) in between packets. These patches have been tested on Haswell ULT platforms with USB 2.0 webcams that support Link PM. The other two patches are clean up. One from Julius clarifies the xHCI endpoint context debugging to make it consistent with standard endpoint addresses, instead of xHCI endpoint context indexes. The one from Alex changes the xHCI driver to be consistent about passing a void pointer to the xHCI IRQ handler. Sarah Sharp

2013-06-06wusbcore: reduce keepalive threshold from timeout/2 to timeout/3Thomas Pugliese2-6/+5
This patch reduces the keepalive threshold of WUSB host controllers from timeout/2 to timeout/3. The keepalive timer fires every timeout/2 ms, but due to rounding errors and jitter, the host may decide not to send a keepalive at timeout/2. By the time the next timer fires, a full timeout period may have expired causing the device to be disconnected without ever having been sent a keepalive. Changing the keepalive threshold to timeout/3 ensures that at least one keepalive will be sent before a device is disconnected. The patch also updates the code to use msecs_to_jiffies consistently.

2013-06-06usb: host: make USB_ARCH_HAS_?HCI obsoleteArnd Bergmann2-65/+7
The three options USB_ARCH_HAS_{EHCI,OHCI,XHCI} are all well beyond their recommended shelf life. They have caused numerous build failures over the years because they are never completely correct, and with the move to splitting out the platform specific back-ends out of the driver, there is no real need for them any more. Also, the use of making USB_ARCH_HAS_HCD depend on it is questionable since one can always enable dummy_hc these days. This patch enables them unconditionally for all platforms and architectures, which means it is now possible to build host controller drivers for machines that are known not to come with this hardware, but that is just how we treat most other drivers. In order to minimise the impact on existing architecture code and defconfig files, all the Kconfig are left present for now. All platforms that currently do 'select USB_ARCH_HAS_*' should subsequently be changed not to select that. All drivers depending on USB_ARCH_HAS_HCD should be changed to depend on USB_SUPPORT instead.

2013-06-06tracing: Use current_uid() for critical time tracingSteven Rostedt (Red Hat)1-1/+9
The irqsoff tracer records the max time that interrupts are disabled. There are hooks in the assembly code that calls back into the tracer when interrupts are disabled or enabled. When they are enabled, the tracer checks if the amount of time they were disabled is larger than the previous recorded max interrupts off time. If it is, it creates a snapshot of the currently running trace to store where the last largest interrupts off time was held and how it happened. During testing, this RCU lockdep dump appeared: [ 1257.829021] =============================== [ 1257.829021] [ INFO: suspicious RCU usage. ] [ 1257.829021] 3.10.0-rc1-test+ #171 Tainted: G W [ 1257.829021] ------------------------------- [ 1257.829021] /home/rostedt/work/git/linux-trace.git/include/linux/rcupdate.h:780 rcu_read_lock() used illegally while idle!

The trace buffer was saved along with various information about the task: comm, pid, uid, priority, etc. The uid is recorded with task_uid(tsk). But this is a macro that uses rcu_read_lock() to retrieve the data, and this happened to happen where RCU is blind (user_enter). As only the preempt and irqs off tracers can have this happen, and they both only have the tsk == current, if tsk == current, use current_uid() instead of task_uid(), as current_uid() does not use RCU as only current can change its uid. This fixes the RCU suspicious splat. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2013-06-06USB: option,zte_ev: move most ZTE CDMA devices to zte_evDan Williams2-26/+22
Per some ZTE Linux drivers I found for the AC2716, the following patch moves most ZTE CDMA devices from option to zte_ev. The blacklist stuff that option does is not required with zte_ev, because it doesn't implement any of the send_setup hooks which the blacklist suppressed. I did not move the 2718 over because I could not find any ZTE Linux drivers for that device, nor even any Windows drivers.
