nvmet-fc: avoid deadlock on delete association path

In the Linux kernel, the following vulnerability has been resolved: nvmet-fc: avoid deadlock on delete association path When deleting an association the shutdown path is deadlocking because we try to flush the nvmet_wq nested. Avoid this by deadlock by deferring the put work into its own work item.

powerpc/pseries: Fix scv instruction crash with kexec

In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries: Fix scv instruction crash with kexec kexec on pseries disables AIL (reloc_on_exc), required for scv instruction support, before other CPUs have been shut down. This means they can execute scv instructions after AIL is disabled, which causes an interrupt at an unexpected entry location that crashes the kernel. Change the kexec sequence to disable AIL after other CPUs have been brought down. As a refresher, the real-mode scv interrupt vector is 0x17000, and the fixed-location head code probably couldn't easily deal with implementing such high addresses so it was just decided not to support that interrupt at all.
