This is a size sensitive structure and randomizing can introduce extra padding that breaks io_uring's fixed size expectations. There are few fields here as it is, half of which need a fixed order to optimally pack, so the randomization isn't providing much. Suggested-by:

Sstc extension allows the guest to program the vstimecmp CSR directly instead of making an SBI call to the hypervisor to program the next event. The timer interrupt is also directly injected to the guest by the hardware in this case. To maintain backward compatibility, the hypervisors also update the vstimecmp in an SBI set_time call if the hardware supports it. Thus, the older kernels in guest also take advantage of the sstc extension. Reviewed-by:

Commit 6f8191fd ("block: simplify disk shutdown") removed the call to blk_get_queue() during gendisk allocation but missed to remove the corresponding cleanup code blk_put_queue() for it. Thus, if the gendisk allocation fails, the request_queue refcount gets decremented and reaches 0, causing blk_mq_release() to be called with a hctx still alive. That triggers a WARNING report, as found by syzkaller: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 23016 at block/blk-mq.c:3881 blk_mq_release+0xf8/0x3e0 block/blk-mq.c:3881 [...] stripped RIP: 0010:blk_mq_release+0xf8/0x3e0 block/blk-mq.c:3881 [...] stripped Call Trace: <TASK> blk_release_queue+0x153/0x270 block/blk-sysfs.c:780 kobject_cleanup lib/kobject.c:673 [inline] kobject_release lib/kobject.c:704 [inline] kref_put include/linux/kref.h:65 [inline] kobject_put+0x1c8/0x540 lib/kobject.c:721 __alloc_disk_node+0x4f7/0x610 block/genhd.c:1388 __blk_mq_alloc_disk+0x13b/0x1f0 block/blk-mq.c:3961 loop_add+0x3e2/0xaf0 drivers/block/loop.c:1978 loop_control_ioctl+0x133/0x620 drivers/block/loop.c:2150 vfs_ioctl fs/ioctl.c:51 [inline] __do_sys_ioctl fs/ioctl.c:870 [inline] __se_sys_ioctl fs/ioctl.c:856 [inline] __x64_sys_ioctl+0x193/0x200 fs/ioctl.c:856 do_syscall_x64 arch/x86/entry/common.c:50 [inline] do_syscall_64+0x35/0xb0 arch/x86/entry/common.c:80 entry_SYSCALL_64_after_hwframe+0x63/0xcd [...] stripped Fixes: 6f8191fd ("block: simplify disk shutdown") Reported-by: syzbot+31c9594f6e43b9289b25@syzkaller.appspotmail.com Suggested-by:

1. Use common arch_stack_walk() infrastructure to avoid duplicated code and avoid taking care of the stack storage and filtering. 2. Add sched_ra (means sched return address) and sched_cfa (means sched call frame address) to thread_info, and store them in switch_to(). 3. Add __get_wchan() implementation. Now we can print the process stack and wait channel by cat /proc/*/stack and /proc/*/wchan. Signed-off-by:

It unwind the stack frame based on prologue code analyze. CONFIG_KALLSYMS is needed, at least the address and length of each function. Three stages when we do unwind, 1) unwind_start(), the prapare of unwinding, fill unwind_state. 2) unwind_done(), judge whether the unwind process is finished or not. 3) unwind_next_frame(), unwind the next frame. Dividing unwinder helps to add new unwinders in the future, e.g.: unwinder_frame, unwinder_orc, .etc. Signed-off-by:

Name "guess unwinder" comes from x86, it scans the stack and reports every kernel text address it finds. Unwinders can be used by dump_stack() and other stacktrace functions. Three stages when we do unwind, 1) unwind_start(), the prapare of unwinding, fill unwind_state. 2) unwind_done(), judge whether the unwind process is finished or not. 3) unwind_next_frame(), unwind the next frame. Add get_stack_info() to get stack info. At present we have irq stack and task stack. The next_sp is the key info between two types of stacks. Dividing unwinder helps to add new unwinders in the future. Signed-off-by:

The kernel entry points of both boot CPU (i.e., kernel_entry) and non- boot CPUs (i.e., smpboot_entry) may be physical address from BootLoader (in DA mode or identity-mapping PG mode). So we should jump to the link address before PG enabled (because DA is disabled at the same time) and just after DMW configured. Specifically: With some older firmwares, non-boot CPUs started with PG enabled, but this need firmware cooperation in the form of a temporary page table, which is deemed unnecessary. OTOH, latest firmware versions configure the non-boot CPUs to start in DA mode, so kernel-side changes are needed. Reviewed-by:

The return value from the call to get_timer_irq() is int, which can be a negative error code. However, the return value is being assigned to an unsigned int variable 'irq', so making 'irq' an int. Eliminate the following coccicheck warning: ./arch/loongarch/kernel/time.c:146:5-8: WARNING: Unsigned expression compared with zero: irq < 0 Reported-by:

When CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS is selected, cpu_max_bits_warn() generates a runtime warning similar as below while we show /proc/cpuinfo. Fix this by using nr_cpu_ids (the runtime limit) instead of NR_CPUS to iterate CPUs.
