2020-10-30arm64/smp: Move rcu_cpu_starting() earlierQian Cai
The call to rcu_cpu_starting() in secondary_start_kernel() is not early enough in the CPU-hotplug onlining process, which results in lockdep splats as follows: WARNING: suspicious RCU usage ----------------------------- kernel/locking/lockdep.c:3497 RCU-list traversed in non-reader section!! other info that might help us debug this: RCU used illegally from offline CPU! rcu_scheduler_active = 1, debug_locks = 1 no locks held by swapper/1/0.

2020-10-30vdpasim: fix MAC address configurationLaurent Vivier
vdpa_sim generates a ramdom MAC address but it is never used by upper layers because the VIRTIO_NET_F_MAC bit is not set in the features list. Because of that, virtio-net always regenerates a random MAC address each time it is loaded whereas the address should only change on vdpa_sim load/unload. Fix that by adding VIRTIO_NET_F_MAC in the features list of vdpa_sim.

2020-10-30vdpa: handle irq bypass register failure caseZhu Lingshan
LKP considered variable 'ret' in vhost_vdpa_setup_vq_irq() as a unused variable, so suggest we remove it. Actually it stores return value of irq_bypass_register_producer(), but we did not check it, we should handle the failure case. This commit will print a message if irq bypass register producer fail, in this case, vqs still remain functional.

2020-10-30vdpa_sim: Fix DMA maskLaurent Vivier
Since commit f959dcd6ddfd ("dma-direct: Fix potential NULL pointer dereference") an error is reported when we load vdpa_sim and virtio-vdpa: [ 129.351207] net eth0: Unexpected TXQ (0) queue failure: -12 It seems that dma_mask is not initialized. This patch initializes dma_mask() and calls dma_set_mask_and_coherent() to fix the problem.

2020-10-30drm/amd/pm: set the initial value of pm info to zeroXiaojian Du
This patch is to set the initial value of pm info to zero. The "value64" is ported to the hwmon and debugfs node, it is a uint64 type. When it is used for NV10/VEGA10/VEGA20, its word size is appropriate, because NV10/VEGA10/VEGA20 has a 64bit smu feature mask, which is separated to high 32bit and low 32bit. But some asic has only 32bit smu feature mask,and this 32bit mask will fill the low 32bit of "value64". So if this "value64" is not initialized to zero, the high 32bit will be filled by a meaningless value, when the whole "value64" is ported to the "SMC Feature Mask" in the "amdgpu_pm_info" on some specific asic, it will be a wrong value.
