Thomas Falcon bbd669a868 ibmvnic: Fix completion structure initialization ... Fix device initialization completion handling for vNIC adapters. Initialize the completion structure on probe and reinitialize when needed. This also fixes a race condition during kdump where the driver can attempt to access the completion struct before it is initialized: Unable to handle kernel paging request for data at address 0x00000000 Faulting instruction address: 0xc0000000081acbe0 Oops: Kernel access of bad area, sig: 11 [#1] LE SMP NR_CPUS=2048 NUMA pSeries Modules linked in: ibmvnic(+) ibmveth sunrpc overlay squashfs loop CPU: 19 PID: 301 Comm: systemd-udevd Not tainted 4.18.0-64.el8.ppc64le #1 NIP: c0000000081acbe0 LR: c0000000081ad964 CTR: c0000000081ad900 REGS: c000000027f3f990 TRAP: 0300 Not tainted (4.18.0-64.el8.ppc64le) MSR: 800000010280b033 <SF,VEC,VSX,EE,FP,ME,IR,DR,RI,LE,TM[E]> CR: 28228288 XER: 00000006 CFAR: c000000008008934 DAR: 0000000000000000 DSISR: 40000000 IRQMASK: 1 GPR00: c0000000081ad964 c000000027f3fc10 c0000000095b5800 c0000000221b4e58 GPR04: 0000000000000003 0000000000000001 000049a086918581 00000000000000d4 GPR08: 0000000000000007 0000000000000000 ffffffffffffffe8 d0000000014dde28 GPR12: c0000000081ad900 c000000009a00c00 0000000000000001 0000000000000100 GPR16: 0000000000000038 0000000000000007 c0000000095e2230 0000000000000006 GPR20: 0000000000400140 0000000000000001 c00000000910c880 0000000000000000 GPR24: 0000000000000000 0000000000000006 0000000000000000 0000000000000003 GPR28: 0000000000000001 0000000000000001 c0000000221b4e60 c0000000221b4e58 NIP [c0000000081acbe0] __wake_up_locked+0x50/0x100 LR [c0000000081ad964] complete+0x64/0xa0 Call Trace: [c000000027f3fc10] [c000000027f3fc60] 0xc000000027f3fc60 (unreliable) [c000000027f3fc60] [c0000000081ad964] complete+0x64/0xa0 [c000000027f3fca0] [d0000000014dad58] ibmvnic_handle_crq+0xce0/0x1160 [ibmvnic] [c000000027f3fd50] [d0000000014db270] ibmvnic_tasklet+0x98/0x130 [ibmvnic] [c000000027f3fda0] [c00000000813f334] tasklet_action_common.isra.3+0xc4/0x1a0 [c000000027f3fe00] [c000000008cd13f4] __do_softirq+0x164/0x400 [c000000027f3fef0] [c00000000813ed64] irq_exit+0x184/0x1c0 [c000000027f3ff20] [c0000000080188e8] __do_irq+0xb8/0x210 [c000000027f3ff90] [c00000000802d0a4] call_do_irq+0x14/0x24 [c000000026a5b010] [c000000008018adc] do_IRQ+0x9c/0x130 [c000000026a5b060] [c000000008008ce4] hardware_interrupt_common+0x114/0x120 Signed-off-by: Thomas Falcon <tlfalcon@linux.ibm.com> Signed-off-by: David S.
