[ Upstream commit 4c62764d ] While running regressions, observed below kernel panic when sdio disconnect called. This is because of, kthread_stop() is taking care of wait_for_completion() by default. When wait_for_completion triggered in kthread_stop and as it was done already, giving kernel panic. Hence, removing redundant wait_for_completion() from rsi_kill_thread(). ... skipping ...

[ Upstream commit 9ce3ebe9 ] In the corner case where the gpio driver probe fails, for whatever reason, the suspend and resume handlers will still be called as they have to be registered as syscore operations. This applies as well when no probe was called while the driver has been built in the kernel. Nicolas tracked this in : https://bugzilla.kernel.org/show_bug.cgi?id=200905 Therefore, add a failsafe in these function, and test if a proper probe succeeded and the driver is functional.

[ Upstream commit 85f9987b ] It was mapped to EIO which can be confusing when user space queries for an object GUID for an object for which the server file system doesn't support (or hasn't saved one). As Amir Goldstein suggested this is similar to ENOATTR (equivalently ENODATA in Linux errno definitions) so changing NT STATUS code mapping for OBJECTID_NOT_FOUND to ENODATA. Signed-off-by:

[ Upstream commit 18fb053f ] There are comments in processor-cyrix.h advising you to _not_ make calls using the deprecated macros in this style: setCx86_old(CX86_CCR4, getCx86_old(CX86_CCR4) | 0x80); This is because it expands the macro into a non-functioning calling sequence. The calling order must be: outb(CX86_CCR2, 0x22); inb(0x23); From the comments: * When using the old macros a line like * setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x88); * gets expanded to: * do { * outb((CX86_CCR2), 0x22); * outb((({ * outb((CX86_CCR2), 0x22); * inb(0x23); * }) | 0x88), 0x23); * } while (0); The new macros fix this problem, so use them instead. Tested on an actual Geode processor. Signed-off-by:

[ Upstream commit 35122495 ] "cat /sys/kernel/debug/bcm2835_thermal/regset" causes a NULL pointer dereference in bcm2835_thermal_debugfs. The driver makes use of the implementation details of the thermal framework to retrieve a pointer to its private data from a struct thermal_zone_device, and gets it wrong - leading to the crash. Instead, store its private data as the drvdata and retrieve the thermal_zone_device pointer from it. Fixes: bcb7dd9e ("thermal: bcm2835: add thermal driver for bcm2835 SoC") Signed-off-by:

[ Upstream commit d9c1bb2f ] On mmap(), perf_events generates a RECORD_MMAP record and then checks which events are interested in this record. There are currently 2 versions of mmap records: RECORD_MMAP and RECORD_MMAP2. MMAP2 is larger. The event configuration controls which version the user level tool accepts. If the event->attr.mmap2=1 field then MMAP2 record is returned. The perf_event_mmap_output() takes care of this. It checks attr->mmap2 and corrects the record fields before putting it in the sampling buffer of the event. At the end the function restores the modified MMAP record fields. The problem is that the function restores the size but not the type. Thus, if a subsequent event only accepts MMAP type, then it would instead receive an MMAP2 record with a size of MMAP record. This patch fixes the problem by restoring the record type on exit. Signed-off-by:
