ARM64: smp: Save CPU registers before IPI_CPU_STOP processing
When a kernel panic occurs on one CPU, other CPUs are instructed to stop
execution via the IPI_CPU_STOP message. These other CPUs dump their stack,
which may not be good enough to reconstruct their context to perform
post-mortem analysis. Dump each CPU's context (before it started
procesing the IPI) into a globally accessible structure and print them on
the dmesg/console to allow for easier post-mortem debugging.
