This is passing IS_ERR() instead of PTR_ERR() so instead of an error code it prints and returns the number 1. Fixes: 4a55ed6f ("i2c: Add GXP SoC I2C Controller") Signed-off-by:

The ppc64le_allmodconfig sets I2C_PASEMI=y and leaves COMPILE_TEST to default to y and I2C_APPLE to default to m, running into a known incompatible configuration that breaks the build [1]. Specifically, a common dependency (i2c-pasemi-core.o in this case) cannot be used by both builtin and module consumers. Disable I2C_APPLE when I2C_PASEMI is a builtin to prevent this.

Pull more s390 updates from Heiko Carstens: - Add empty command line parameter handling stubs to kernel for all command line parameters which are handled in the decompressor. This avoids invalid "Unknown kernel command line parameters" messages from the kernel, and also avoids that these will be incorrectly passed to user space. This caused already confusion, therefore add the empty stubs - Add missing phys_to_virt() handling to machine check handler - Introduce and use a union to be used for zcrypt inline assemblies. This makes sure that only a register wide member of the union is passed as input and output parameter to inline assemblies, while usual C code uses other members of the union to access bit fields of it - Add and use a READ_ONCE_ALIGNED_128() macro, which can be used to atomically read a 128-bit value from memory. This replaces the (mis-)use of the 128-bit cmpxchg operation to do the same in cpum_sf code. Currently gcc does not generate the used lpq instruction if __READ_ONCE() is used for aligned 128-bit accesses, therefore use this s390 specific helper - Simplify machine check handler code if a task needs to be killed because of e.g. register corruption due to a machine malfunction - Perform CPU reset to clear pending interrupts and TLB entries on an already stopped target CPU before delegating work to it - Generate arch/s390/boot/vmlinux.map link map for the decompressor, when CONFIG_VMLINUX_MAP is enabled for debugging purposes - Fix segment type handling for dcssblk devices. It incorrectly always returned type "READ/WRITE" even for read-only segements, which can result in a kernel panic if somebody tries to write to a read-only device - Sort config S390 select list again - Fix two kprobe reenter bugs revealed by a recently added kprobe kunit test * tag 's390-6.3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390/kprobes: fix current_kprobe never cleared after kprobes reenter s390/kprobes: fix irq mask clobbering on kprobe reenter from post_handler s390/Kconfig: sort config S390 select list again s390/extmem: return correct segment type in __segment_load() s390/decompressor: add link map saving s390/smp: perform cpu reset before delegating work to target cpu s390/mcck: cleanup user process termination path s390/cpum_sf: use READ_ONCE_ALIGNED_128() instead of 128-bit cmpxchg s390/rwonce: add READ_ONCE_ALIGNED_128() macro s390/ap,zcrypt,vfio: introduce and use ap_queue_status_reg union s390/nmi: fix virtual-physical address confusion s390/setup: do not complain about parameters handled in decompressor

The block layer might merge together discard requests up until the max_discard_segments limit is hit, but blk_insert_cloned_request checks the segment count against max_segments regardless of the req op. This can result in errors like the following when discards are issued through a DM device and max_discard_segments exceeds max_segments for the queue of the chosen underlying device. blk_insert_cloned_request: over max segments limit. (256 > 129) Fix this by looking at the req_op and enforcing the appropriate segment limit - max_discard_segments for REQ_OP_DISCARDs and max_segments for everything else. Signed-off-by:

Recent test_kprobe_missed kprobes kunit test uncovers the following problem. Once kprobe is triggered from another kprobe (kprobe reenter), all future kprobes on this cpu are considered as kprobe reenter, thus pre_handler and post_handler are not being called and kprobes are counted as "missed". Commit b9599798 ("[S390] kprobes: activation and deactivation") introduced a simpler scheme for kprobes (de)activation and status tracking by using push_kprobe/pop_kprobe, which supposed to work for both initial kprobe entry as well as kprobe reentry and helps to avoid handling those two cases differently. The problem is that a sequence of calls in case of kprobes reenter: push_kprobe() <- NULL (current_kprobe) push_kprobe() <- kprobe1 (current_kprobe) pop_kprobe() -> kprobe1 (current_kprobe) pop_kprobe() -> kprobe1 (current_kprobe) leaves "kprobe1" as "current_kprobe" on this cpu, instead of setting it to NULL. In fact push_kprobe/pop_kprobe can only store a single state (there is just one prev_kprobe in kprobe_ctlblk). Which is a hack but sufficient, there is no need to have another prev_kprobe just to store NULL. To make a simple and backportable fix simply reset "prev_kprobe" when kprobe is poped from this "stack". No need to worry about "kprobe_status" in this case, because its value is only checked when current_kprobe != NULL.

The problem is that when kprobe is triggered from another kprobe post_handler current sequence of enable_singlestep / disable_singlestep is the following: enable_singlestep <- original kprobe (saves kprobe_saved_imask) enable_singlestep <- kprobe triggered from post_handler (clobbers kprobe_saved_imask) disable_singlestep <- kprobe triggered from post_handler (restores kprobe_saved_imask) disable_singlestep <- original kprobe (restores wrong clobbered kprobe_saved_imask) There is just one kprobe_ctlblk per cpu and both calls saves and loads irq mask to kprobe_saved_imask. To fix the problem simply move resume_execution (which calls disable_singlestep) before calling post_handler. This also fixes the problem that post_handler is called with pt_regs which were not yet adjusted after single-stepping. Cc: stable@vger.kernel.org Fixes: 4ba069b8 ("[S390] add kprobes support.")

The single difference between returning 0 and returning an error code in a platform remove callback is that in the latter case the platform core emits a warning about the error being ignored. at91wdt_remove() already emits a warning in the error case, so suppress the more generic (and less helpful) one by returning 0.

MT7621 SoC has a system controller node. Watchdog need to access to reset status register. Ralink architecture and related driver are old and from the beggining they are using some architecture dependent operations for accessing this shared registers through 'asm/mach-ralink/ralink_regs.h' header file. However this is not ideal from a driver perspective which can just access to the system controller registers in an arch independent way using regmap syscon APIs. Update Kconfig accordingly to select new added dependencies and allow driver to be compile tested. Signed-off-by:
