commit c80b4495 upstream. This patch adds quirks for Entrega Technologies (later Xircom PortGear) USB- SCSI converters. They use Shuttle Technology EUSB-01/EUSB-S1 chips. The US_FL_SCM_MULT_TARG quirk is needed to allow multiple devices on the SCSI chain to be accessed. Without it only the (single) device with SCSI ID 0 can be used. The standalone converter sold by Entrega had model number U1-SC25. Xircom acquired Entrega and re-branded the product line PortGear. The PortGear USB to SCSI Converter (model PGSCSI) is internally identical to the Entrega product, but later models may use a different USB ID. The Entrega-branded units have USB ID 1645:0007, as does my Xircom PGSCSI, but the Windows and Macintosh drivers also support 085A:0028. Entrega also sold the "Mac USB Dock", which provides two USB ports, a Mac (8-pin mini-DIN) serial port and a SCSI port. It appears to the computer as a four-port hub, USB-serial, and USB-SCSI converters. The USB-SCSI part may have initially used the same ID as the standalone U1-SC25 (1645:0007), but later production used 085A:0026. My Xircom PortGear PGSCSI has bcdDevice=0x0100. Units with bcdDevice=0x0133 probably also exist. This patch adds quirks for 1645:0007, 085A:0026 and 085A:0028. The Windows driver INF file also mentions 085A:0032 "PortStation SCSI Module", but I couldn't find any mention of that actually existing in the wild; perhaps it was cancelled before release?

commit b6a3ed67 upstream. Hi, The Ariston Technologies iConnect 025 and iConnect 050 (also known as e.g. iSCSI-50) are SCSI-USB converters which use Shuttle Technology/SCM Microsystems chips. Only the connectors differ; both have the same USB ID. The US_FL_SCM_MULT_TARG quirk is required to use SCSI devices with ID other than 0. I don't have one of these, but based on the other entries for Shuttle/ SCM-based converters this patch is very likely correct. I used 0x0000 and 0x9999 for bcdDeviceMin and bcdDeviceMax because I'm not sure which bcdDevice value the products use. Signed-off-by:

commit 7312b5dd upstream. Old code in ehci-hcd tries to expedite disabling endpoints after the controller has stopped, by destroying the endpoint's associated QH without first unlinking the QH. This was necessary back when the driver wasn't so careful about keeping track of the controller's state. But now we are careful about it, and the driver knows that when the controller isn't running, no unlinking delay is needed. Furthermore, skipping the unlink step will trigger a BUG() in qh_destroy() when the preceding QH is released, because the link pointer will be non-NULL. Removing the lines that skip the unlinking step and go directly to QH_STATE_IDLE fixes the problem. Signed-off-by:

commit 080af20c upstream. There is a race between nfs4_state_manager() and nfs_server_remove_lists() that happens during a nfsv3 mount. The v3 mount notices there is already a supper block so nfs_server_remove_lists() called which uses the nfs_client_lock spin lock to synchronize access to the client list. At the same time nfs4_state_manager() is running through the client list looking for work to do, using the same lock. When nfs4_state_manager() wins the race to the list, a v3 client pointer is found and not ignored properly which causes the panic. Moving some protocol checks before the state checking avoids the panic. Signed-off-by:

commit 86fd887b upstream. Commit 20cde694 ("x86, ia64: Move EFI_FB vga_default_device() initialization to pci_vga_fixup()") moved boot video device detection from efifb to x86 and ia64 pci/fixup.c. For dual-GPU Apple computers above change represents a regression as code in efifb did forcefully override vga_default_device while the merge did not (vgaarb happens prior to PCI fixup). To improve on initial device selection by vgaarb (it cannot know if PCI device not behind bridges see/decode legacy VGA I/O or not), move the screen_info based check from pci_video_fixup() to vgaarb's init function and use it to refine/override decision taken while adding the individual PCI VGA devices. This way PCI fixup has no reason to adjust vga_default_device anymore but can depend on its value for flagging shadowed VBIOS. This has the nice benefit of removing duplicated code but does introduce a would cause compile to fail without it. Link: https://bugzilla.kernel.org/show_bug.cgi?id=84461Reported-and-Tested-By:

commit 20cde694 upstream. Commit b4aa0163 ("efifb: Implement vga_default_device() (v2)") added efifb vga_default_device() so EFI systems that do not load shadow VBIOS or setup VGA get proper value for boot_vga PCI sysfs attribute on the corresponding PCI device. Xorg doesn't detect devices when boot_vga=0, e.g., on some EFI systems such as MacBookAir2,1. Xorg detects the GPU and finds the DRI device but then bails out with "no devices detected". Note: When vga_default_device() is set boot_vga PCI sysfs attribute reflects its state. When unset this attribute is 1 whenever IORESOURCE_ROM_SHADOW flag is set. With introduction of sysfb/simplefb/simpledrm efifb is getting obsolete while having native drivers for the GPU also makes selecting sysfb/efifb optional. Remove the efifb implementation of vga_default_device() and initialize vgaarb's vga_default_device() with the PCI GPU that matches boot screen_info in pci_fixup_video().

commit fbfb872f upstream. The TPIDRURO and TPIDRURW registers need to be flushed during exec; otherwise TLS information is potentially leaked. TPIDRURO in particular needs careful treatment. Since flush_thread basically needs the same code used to set the TLS in arm_syscall, pull that into a common set_tls helper in tls.h and use it in both places. Similarly, TEEHBR needs to be cleared during exec as well. Clearing its save slot in thread_info isn't right as there is no guarantee that a thread switch will occur before the new program runs. Just setting the register directly is sufficient. Signed-off-by:

commit d4f51956 upstream. If touchscreen mode is enabled and a conversion is requested on another channel, the result in the last converted data register can be a touchscreen relative value. Starting a conversion involves to do a conversion for all active channel. It starts with ADC channels and ends with touchscreen channels. Then if ADC_LCD register is not read quickly, its content may be a touchscreen conversion. To remove this temporal constraint, the conversion value is taken from the channel data register.

commit c0120679 upstream. We are getting more and more reports about LG laptops not having functioning keyboard if we try to deactivate keyboard during probe. Given that having keyboard deactivated is merely "nice to have" instead of a hard requirement for probing, let's disable it on all LG boxes instead of trying to hunt down particular models.

commit 7a9744cb upstream. When a driver is set up without the jack detection explicitly (either by passing a model option or via a specific fixup), the pin powermap of IDT/STAC codecs is set up wrongly, resulting in the silence output. It's because of a logic failure in stac_init_power_map(). It tries to avoid creating a callback for the pins that have other auto-hp and auto-mic callbacks, but the check is done in a wrong way at a wrong time. The stac_init_power_map() should be called after creating other jack detection ctls, and the jack callback should be created only for jack-detectable widgets. This patch fixes the check in stac_init_power_map() and its callee at the right place, after snd_hda_gen_build_controls(). Reported-by:

commit b97c60ab upstream. Currently configuration of the CDCLK pad is being overwritten in the i2s_shutdown() callback in order to gate the SoC output clock. However if an ASoC machine driver doesn't restore that clock settings each time after opening the sound device this results in the CDCLK pin being permanently configured into input mode. I.e. the output clock will always stay disabled. Fix that by saving the CDCLKCON bit state in i2s_shutdown() and and restoring it in the i2s_startup() callback. Signed-off-by:

commit 3577af70 upstream. We saw a kernel soft lockup in perf_remove_from_context(), it looks like the `perf` process, when exiting, could not go out of the retry loop. Meanwhile, the target process was forking a child. So either the target process should execute the smp function call to deactive the event (if it was running) or it should do a context switch which deactives the event. It seems we optimize out a context switch in perf_event_context_sched_out(), and what's more important, we still test an obsolete task pointer when retrying, so no one actually would deactive that event in this situation. Fix it directly by reloading the task pointer in perf_remove_from_context(). This should cure the above soft lockup. Signed-off-by:

commit a040803a upstream. Since commit 1dbfa187 ("ARM: irq migration: force migration off CPU going down") the ARM interrupt migration code on cpu offline calls irqchip.irq_set_affinity() with the argument force=true. At the point of this change the argument had no effect because it was not used by any interrupt chip driver and there was no semantics defined. This changed with commit 01f8fa4f ("genirq: Allow forcing cpu affinity of interrupts") which made the force argument useful to route interrupts to not yet online cpus without checking the target cpu against the cpu online mask. The following commit ffde1de6 ("irqchip: gic: Support forced affinity setting") implemented this for the GIC interrupt controller. As a consequence the ARM cpu offline irq migration fails if CPU0 is offlined, because CPU0 is still set in the affinity mask and the validataion against cpu online mask is skipped to the force argument being true. The following first_cpu(mask) selection always selects CPU0 as the target. Solve the issue by calling irq_set_affinity() with force=false from the CPU offline irq migration code so the GIC driver validates the affinity mask against CPU online mask and therefore removes CPU0 from the possible target candidates. Tested on TC2 hotpluging CPU0 in and out. Without this patch the system locks up as the IRQs are not migrated away from CPU0. Signed-off-by:

commit 29593fd5 upstream. Commit dc4d7b37 (MIPS: ZBOOT: gather string functions into string.c) moved the string related functions into a separate file, which might cause the following build error, depending on the configuration: | CC arch/mips/boot/compressed/decompress.o | In file included from linux/arch/mips/boot/compressed/../../../../lib/decompress_unxz.c:234:0, | from linux/arch/mips/boot/compressed/decompress.c:67: | linux/arch/mips/boot/compressed/../../../../lib/xz/xz_dec_stream.c: In function 'fill_temp': | linux/arch/mips/boot/compressed/../../../../lib/xz/xz_dec_stream.c:162:2: error: implicit declaration of function 'memcpy' [-Werror=implicit-function-declaration] | cc1: some warnings being treated as errors | linux/scripts/Makefile.build:308: recipe for target 'arch/mips/boot/compressed/decompress.o' failed | make[6]: *** [arch/mips/boot/compressed/decompress.o] Error 1 | linux/arch/mips/Makefile:308: recipe for target 'vmlinuz' failed It does not fail with the standard configuration, as when CONFIG_DYNAMIC_DEBUG is not enabled <linux/string.h> gets included in include/linux/dynamic_debug.h. There might be other ways for it to get indirectly included. We can't add the include directly in xz_dec_stream.c as some architectures might want to use a different version for the boot/ directory (see for example arch/x86/boot/string.h). Signed-off-by:
