2011-12-21USB: option: Removing one bogus and adding some new Huawei combinationsBjørn Mork
commit 02a551c9755b799579e0a093bcc99b80b4dc1453 upstream. Huawei use the product code HUAWEI_PRODUCT_E353 (0x1506) for a number of different devices, which each can appear with a number of different descriptor sets. Different types of interfaces can be identified by looking at the subclass and protocol fields Subclass 1 protocol 8 is actually the data interface of a CDC ECM set, with subclass 1 protocol 9 as the control interface. Neither support serial data communcation, and cannot therefore be supported by this driver. At the same time, add a few other sets which appear if the device is configured in "Windows mode" using this modeswitch message: 55534243000000000000000000000011060000000100000000000000000000 Signed-off-by: Bjørn Mork <bjorn@mork.no> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2011-12-21ibft: Fix finding IBFT ACPI table on UEFIYinghai Lu
commit 935a9fee51c945b8942be2d7b4bae069167b4886 upstream. Found one system with UEFI/iBFT, kernel does not detect the iBFT during iscsi_ibft module loading. Root cause: on x86 (UEFI), we are calling of find_ibft_region() much earlier - specifically in setup_arch() before ACPI is enabled. Try to split acpi checking code out and call that later At that time ACPI iBFT already get permanent mapped with ioremap. So isa_virt_to_bus() will get wrong phys from right virt address. We could just skip that phys address printing. For legacy one, print the found address early. -v2: update comments and description according to Konrad. -v3: fix problem about module use case that is found by Konrad. -v4: use acpi_get_table() instead of acpi_table_parse() to handle module use case that is found by Konrad again..

commit e58f516ff4730c4047c3f104b061f7a03e9a263c upstream. When we can't configure the dma channel we want to fall back to PIO. We do this by setting host->do_dma to zero. This does not work as do_dma is used to see whether dma can be used for the current transfer. Instead, we have to set host->dma to NULL.

2011-12-21iscsi-target: Fix residual count hanlding + remove iscsi_cmd->residual_countNicholas Bellinger
commit 7e46cf02687e40197ae07c623e660be2a2720064 upstream. This patch fixes iscsi-target handling of underflow where residual data is causing an OOPs by using the incorrect iscsi_cmd_t->data_length initially assigned in iscsit_allocate_se_cmd(). It resets iscsi_cmd_t->data_length from se_cmd_t->data_length after transport_generic_allocate_tasks() has been invoked in iscsit_handle_scsi_cmd() RX context, and converts iscsi_cmd->residual_count usage to access iscsi_cmd->se_cmd.residual_count to get the proper residual count set by target-core.

transport_generic_map_mem_to_cmd commit fef58a6096770ed6ab49103a430cc755254a74d9 upstream. This patch changes transport_generic_map_mem_to_cmd() to reject SCSI data overflow and to send exception status with CHECK_CONDITION + TCM_INVALID_CDB_FIELD for fabrics that are passing a pre-populated struct scatterlist (eg: tcm_loop and iscsi-target) being mapped into se_cmd->t_data_sg and se_cmd->t_data_nents.

2011-12-09oprofile: Fix crash when unloading module (hr timer mode)Robert Richter
commit 87121ca504fd1d963a66b3fb0c72054b0fd9a177 upstream. Oprofile may crash in a KVM guest while unlaoding modules. This happens if oprofile_arch_init() fails and oprofile switches to the hr timer mode as a fallback. In this case oprofile_arch_exit() is called, but it never was initialized properly which causes the crash. This patch fixes this. oprofile: using timer interrupt.

2011-12-09rtc: Fix some bugs that allowed accumulating time drift in suspend/resumeArve Hjønnevåg
commit 6a8943d9ec2567572fca25cf69ad45844d0141a3 upstream. The current code checks if abs(delta_delta.tv_sec) is greater or equal to two before it discards the old delta value, but this can trigger at close to -1 seconds since -1.000000001 seconds is stored as tv_sec -2 and tv_nsec 999999999 in a normalized timespec. rtc_resume had an early return check if the rtc value had not changed since rtc_suspend. This effectivly stops time for the duration of the short sleep. Check if sleep_time is positive after all the adjustments have been applied instead since this allows the old_system adjustment in rtc_suspend to have an effect even for short sleep cycles.

2011-12-09xHCI: fix bug in xhci_clear_command_ring()Andiry Xu
commit 158886cd2cf4599e04f9b7e10cb767f5f39b14f1 upstream. When system enters suspend, xHCI driver clears command ring by writing zero to all the TRBs. However, this also writes zero to the Link TRB, and the ring is mangled. This may cause driver accesses wrong memory address and the result is unpredicted. When clear the command ring, keep the last Link TRB intact, only clear its cycle bit. This should fix the "command ring full" issue reported by Oliver Neukum. This should be backported to stable kernels as old as 2.6.37, since the commit 89821320 "xhci: Fix command ring replay after resume" is merged.

2011-12-09USB: EHCI: fix HUB TT scheduling issue with iso transferThomas Poussevin
commit 811c926c538f7e8d3c08b630dd5844efd7e000f6 upstream. The current TT scheduling doesn't allow to play and then record on a full-speed device connected to a high speed hub. The IN iso stream can only start on the first uframe (0-2 for a 165 us) because of CSPLIT transactions. For the OUT iso stream there no such restriction. uframe 0-5 are possible. The idea of this patch is that the first uframe are precious (for IN TT iso stream) and we should allocate the last uframes first if possible. For that we reverse the order of uframe allocation (last uframe first). Here an example : hid interrupt stream ---------------------------------------------------------------------- uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ---------------------------------------------------------------------- max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 | ---------------------------------------------------------------------- used usecs on a frame | 13 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | ---------------------------------------------------------------------- iso OUT stream ---------------------------------------------------------------------- uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ---------------------------------------------------------------------- max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 | ---------------------------------------------------------------------- used usecs on a frame | 13 | 125 | 39 | 0 | 0 | 0 | 0 | 0 | ---------------------------------------------------------------------- There no place for iso IN stream (uframe 0-2 are used) and we got "cannot submit datapipe for urb 0, error -28: not enough bandwidth" error. With the patch this become. iso OUT stream ---------------------------------------------------------------------- uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ---------------------------------------------------------------------- max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 | ---------------------------------------------------------------------- used usecs on a frame | 13 | 0 | 0 | 0 | 125 | 39 | 0 | 0 | ---------------------------------------------------------------------- iso IN stream ---------------------------------------------------------------------- uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ---------------------------------------------------------------------- max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 | ---------------------------------------------------------------------- used usecs on a frame | 13 | 0 | 125 | 40 | 125 | 39 | 0 | 0 | ---------------------------------------------------------------------- Signed-off-by: Matthieu Castet <matthieu.castet@parrot.com> Signed-off-by: Thomas Poussevin <thomas.poussevin@parrot.com> Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

commit 5d193ce8f1fa7c67c7fd7be2c03ef31eed344a4f upstream. Currently the driver tries to save context in the suspend path, but will cause an abort if the device is already runtime suspended. This happens, for example, if MUSB loaded/compiled-in, in host mode, but no USB devices are attached. MUSB will be runtime suspended, but then attempting a system suspend will crash due to the context save being attempted while the device is disabled. On OMAP, as of v3.1, the driver's ->runtime_suspend() callback will be called late in the suspend path (by the PM domain layer) if the driver is not already runtime suspended, ensuring a full shutdown. Therefore, the context save is not needed in the ->suspend() method since it will be called in the ->runtime_suspend() method anyways (similarily for resume.) NOTE: this leaves the suspend/resume methods basically empty (with some FIXMEs and comments, but I'll leave it to the maintainers to decide whether to remove them.

2011-12-09regulator: twl: fix twl4030 support for smps regulatorsTero Kristo
commit ba305e31e88ea5c2f598ff9fbc5424711a429e30 upstream. SMPS regulator voltage control differs from the one of the LDO ones. Current TWL code was using LDO regulator ops for controlling the SMPS regulators, which fails. This was fixed fixed by adding separate regulator type which uses correct logic and calculations for the voltage levels.
