2015-06-10xen: netback: read hotplug script once at start of day.Ian Campbell
[ Upstream commit 31a418986a5852034d520a5bab546821ff1ccf3d ] When we come to tear things down in netback_remove() and generate the uevent it is possible that the xenstore directory has already been removed (details below). In such cases netback_uevent() won't be able to read the hotplug script and will write a xenstore error node. A recent change to the hypervisor exposed this race such that we now sometimes lose it (where apparently we didn't ever before). Instead read the hotplug script configuration during setup and use it for the lifetime of the backend device. The apparently more obvious fix of moving the transition to state=Closed in netback_remove() to after the uevent does not work because it is possible that we are already in state=Closed (in reaction to the guest having disconnected as it shutdown). Being already in Closed means the toolstack is at liberty to start tearing down the xenstore directories. In principal it might be possible to arrange to unregister the device sooner (e.g on transition to Closing) such that xenstore would still be there but this state machine is fragile and prone to anger... A modern Xen system only relies on the hotplug uevent for driver domains, when the backend is in the same domain as the toolstack it will run the necessary setup/teardown directly in the correct sequence wrt xenstore changes.

2015-06-10net: dp83640: fix broken calibration routine.Richard Cochran
[ Upstream commit 397a253af5031de4a4612210055935309af4472c ] Currently, the calibration function that corrects the initial offsets among multiple devices only works the first time. If the function is called more than once, the calibration fails and bogus offsets will be programmed into the devices. In a well hidden spot, the device documentation tells that trigger indexes 0 and 1 are special in allowing the TRIG_IF_LATE flag to actually work. This patch fixes the issue by using one of the special triggers during the recalibration method. Signed-off-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S.

"dgap_driver.h" commit 6319c61aecc7acaf39a1dc0e81a8aac6a17499ee upstream. Normally, the macros from command line are system specific macros (e.g __linux, __KERNEL__ ...), and module own macros are usually defined in their header files. DG_NAME and DG_PART are driver 'dgap' owned macros which are used by multiple files within driver, and need be defined in the driver main header file. So move DG_NAME and DG_PART to "dgap_driver.h", it not only can make code clearer, but also can avoid compiling failure when EXTRA_CFLAGS appended to make command line (e.g. "EXTRA_CFLAGS=-W").

2015-06-03ACPI / init: Fix the ordering of acpi_reserve_resources()Rafael J. Wysocki
commit b9a5e5e18fbf223502c0b2264c15024e393da928 upstream. Since acpi_reserve_resources() is defined as a device_initcall(), there's no guarantee that it will be executed in the right order with respect to the rest of the ACPI initialization code. On some systems this leads to breakage if, for example, the address range that should be reserved for the ACPI fixed registers is given to the PCI host bridge instead if the race is won by the wrong code path. Fix this by turning acpi_reserve_resources() into a void function and calling it directly from within the ACPI initialization sequence.

commit 3c0213d17a09601e0c6c0ae0e27caf70d988290f upstream. When the v3 hardware sees more than one finger, it uses the semi-mt protocol to report the touches. However, it currently works when num_fingers is 0, 1 or 2, but when it is 3 and above, it sends only 1 finger as if num_fingers was 1. This confuses userspace which knows how to deal with extra fingers when all the slots are used, but not when some are missing.

commit 6e9eac2dcee5e19f125967dd2be3e36558c42fff upstream. If any memory allocation in resize_stripes fails we will return -ENOMEM, but in some cases we update conf->pool_size anyway. This means that if we try again, the allocations will be assumed to be larger than they are, and badness results. So only update pool_size if there is no error.

2015-06-03thermal: step_wise: Revert optimizationJean Delvare
Commit 178c2490b99f898efc06d1ad75cadc84f13021a6 ("thermal: step_wise: cdev only needs update on a new target state") broke driver acerhdf. That driver abused the step_wise thermal governor until the bang_bang governor was available, and the optimization broke this usage model. Kernels v3.12 to v3.18 are affected. In v3.19 the acerhdf driver was switched to the bang_bang governor and that solved the problem. For kernels v3.12 to v3.17, the bang_bang governor isn't available yet so the easiest fix is to revert the optimization.

commit f230e8ffc03f17bd9d6b90ea890b8252a8cc1821 upstream. This patch fixes an inverted return value of the gpio get_direction function. The wrong value causes the direction sysfs entry and GPIO debugfs file to indicate incorrect GPIO direction settings. In some cases it also prevents setting GPIO output values.

commit 09c5b4803a80a5451d950d6a539d2eb311dc0fb1 upstream. When the LPM policy is set to ATA_LPM_MAX_POWER, the device might generate a spurious PHY event that cuases errors on the link. Ignore this event if it occured within 10s after the policy change. The timeout was chosen observing that on a Dell XPS13 9333 these spurious events can occur up to roughly 6s after the policy change.

2015-06-03USB: visor: Match I330 phone more preciselyJason A. Donenfeld
commit 82ee3aeb9295c5fc37fd2ddf20f13ac2b40ec97d upstream. Samsung has just released a portable USB3 SSD, coming in a very small and nice form factor. It's USB ID is 04e8:8001, which unfortunately is already used by the Palm Visor driver for the Samsung I330 phone cradle. Having pl2303 or visor pick up this device ID results in conflicts with the usb-storage driver, which handles the newly released portable USB3 SSD. To work around this conflict, I've dug up a mailing list post [1] from a long time ago, in which a user posts the full USB descriptor information. The most specific value in this appears to be the interface class, which has value 255 (0xff). Since usb-storage requires an interface class of 0x8, I believe it's correct to disambiguate the two devices by matching on 0xff inside visor.

2015-06-03xhci: Solve full event ring by increasing TRBS_PER_SEGMENT to 256Mathias Nyman
commit 18cc2f4cbbaf825a4fedcf2d60fd388d291e0a38 upstream. Our event ring consists of only one segment, and we risk filling the event ring in case we get isoc transfers with short intervals such as webcams that fill a TD every microframe (125us) With 64 TRB segment size one usb camera could fill the event ring in 8ms. A setup with several cameras and other devices can fill up the event ring as it is shared between all devices. This has occurred when uvcvideo queues 5 * 32TD URBs which then get cancelled when the video mode changes. The cancelled URBs are returned in the xhci interrupt context and blocks the interrupt handler from handling the new events. A full event ring will block xhci from scheduling traffic and affect all devices conneted to the xhci, will see errors such as Missed Service Intervals for isoc devices, and and Split transaction errors for LS/FS interrupt devices. Increasing the TRB_PER_SEGMENT will also increase the default endpoint ring size, which is welcome as for most isoc transfer we had to dynamically expand the endpoint ring anyway to be able to queue the 5 * 32TDs uvcvideo queues. The default size used to be 64 TRBs per segment Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Jiri Slaby <jslaby@suse.cz>
2015-06-03xhci: fix isoc endpoint dequeue from advancing too far on transaction errorMathias Nyman
commit d104d0152a97fade389f47635b73a9ccc7295d0b upstream. Isoc TDs usually consist of one TRB, sometimes two. When all goes well we receive only one success event for a TD, and move the dequeue pointer to the next TD. This fails if the TD consists of two TRBs and we get a transfer error on the first TRB, we will then see two events for that TD. Fix this by making sure the event we get is for the last TRB in that TD before moving the dequeue pointer to the next TD. This will resolve some of the uvc and dvb issues with the "ERROR Transfer event TRB DMA ptr not part of current TD" error message Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Jiri Slaby <jslaby@suse.cz>

commit 77bb3dfdc0d554befad58fdefbc41be5bc3ed38a upstream. A non-percpu VIRQ (e.g., VIRQ_CONSOLE) may be freed on a different VCPU than it is bound to. This can result in a race between handle_percpu_irq() and removing the action in __free_irq() because handle_percpu_irq() does not take desc->lock. The interrupt handler sees a NULL action and oopses. Only use the percpu chip/handler for per-CPU VIRQs (like VIRQ_TIMER). # cat /proc/interrupts | grep virq 40: 87246 0 xen-percpu-virq timer0 44: 0 0 xen-percpu-virq debug0 47: 0 20995 xen-percpu-virq timer1 51: 0 0 xen-percpu-virq debug1 69: 0 0 xen-dyn-virq xen-pcpu 74: 0 0 xen-dyn-virq mce 75: 29 0 xen-dyn-virq hvc_console Signed-off-by: David Vrabel <david.vrabel@citrix.com> Signed-off-by: Jiri Slaby <jslaby@suse.cz>

commit 59c816c1f24df0204e01851431d3bab3eb76719c upstream. This code in vhost_scsi_make_tpg() is confusing because we limit "tpgt" to UINT_MAX but the data type of "tpg->tport_tpgt" and that is a u16. I looked at the context and it turns out that in vhost_scsi_set_endpoint(), "tpg->tport_tpgt" is used as an offset into the vs_tpg[] array which has VHOST_SCSI_MAX_TARGET (256) elements so anything higher than 255 then it is invalid. I have made that the limit now. In vhost_scsi_send_evt() we mask away values higher than 255, but now that the limit has changed, we don't need the mask.

commit 9493c2422cae272d6f1f567cbb424195defe4176 upstream. Remove 2 redundant extern inline functions: qla8044_set_qsnt_ready() and qla8044_need_reset_handler(). At present, within upstream next kernel source code, they are only used within "drivers/scsi/qla2xxx/qla_nx2.c". The related error and warnings (with allmodconfig under tile): CC [M] drivers/scsi/qla2xxx/qla_nx2.o drivers/scsi/qla2xxx/qla_nx2.c:1633:1: error: static declaration of 'qla8044_need_reset_handler' follows non-static declaration qla8044_need_reset_handler(struct scsi_qla_host *vha) ^ In file included from drivers/scsi/qla2xxx/qla_def.h:3706:0, from drivers/scsi/qla2xxx/qla_nx2.c:11: drivers/scsi/qla2xxx/qla_gbl.h:756:20: note: previous declaration of 'qla8044_need_reset_handler' was here extern inline void qla8044_need_reset_handler(struct scsi_qla_host *vha); ^ drivers/scsi/qla2xxx/qla_gbl.h:756:20: warning: inline function 'qla8044_need_reset_handler' declared but never defined make[3]: *** [drivers/scsi/qla2xxx/qla_nx2.o] Error 1 make[2]: *** [drivers/scsi/qla2xxx] Error 2 make[1]: *** [drivers/scsi] Error 2 make: *** [drivers] Error 2 CC [M] drivers/scsi/qla2xxx/qla_tmpl.o In file included from drivers/scsi/qla2xxx/qla_def.h:3706:0, from drivers/scsi/qla2xxx/qla_tmpl.c:7: drivers/scsi/qla2xxx/qla_gbl.h:755:20: warning: inline function 'qla8044_set_qsnt_ready' declared but never defined extern inline void qla8044_set_qsnt_ready(struct scsi_qla_host *vha); ^ Signed-off-by: Chen Gang <gang.chen.5i5j@gmail.com> Acked-by: Saurav Kashyap <saurav.kashyap@qlogic.com> Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jiri Slaby <jslaby@suse.cz>
2015-05-26staging, rtl8192e, LLVMLinux: Remove unused inline prototypeBehan Webster
commit 62ec95f86d2850b7ce6d73fb236a6fcf48411aea upstream. rtllib_probe_req is defined as "static inline" in rtllib_softmac.c however it is declared differently as "extern inline" in rtllib_softmac.h. Since it isn't used outside of the scope of rtllib_softmac, it makes sense to remove the incorrect declaration.

2015-05-26staging: rtl8712, rtl8712: avoid lots of build warningsArnd Bergmann
commit 0c9f3a65c5eb7fe1fc611a22eb8a8b71ea865998 upstream. The rtl8712 driver has an 'extern inline' function that contains an 'if', which causes lots of warnings with CONFIG_PROFILE_ALL_BRANCHES overriding the definition of 'if': drivers/staging/rtl8712/ieee80211.h:759:229: warning: '______f' is static but declared in inline function 'ieee80211_get_hdrlen' which is not static [enabled by default] This changes the driver to use 'static inline' instead, which happens to be the correct annotation anyway.

2015-05-26staging, rtl8192e, LLVMLinux: Change extern inline to static inlineBehan Webster
commit 6d91857d4826b382b3fd4fad95f52713be646f96 upstream. With compilers which follow the C99 standard (like modern versions of gcc and clang), "extern inline" does the opposite thing from older versions of gcc (emits code for an externally linkable version of the inline function). "static inline" does the intended behavior in all cases instead.

2015-05-26staging: wlags49_h2: fix extern inline functionsGreg Kroah-Hartman
Patch not upstream as this driver is deleted there. Fix up some "extern inline" functions as they break the build when using a "modern" complier (i.e. gcc5). Signed-off-by: Jiri Slaby <jslaby@suse.cz>
