First, by this point you have converted all of the accelerators, so I would
expect cpus_accel to always be non-null. I would expect a patch immediately
preceding this one to place an assert to that effect somewhere in the startup
code, and to remove all of the checks.
Second, I would prefer that all methods be non-null, so that you don't need to
check that either. This patch would add generic_handle_interrupt (perhaps
named cpus_accel_default_handle_interrupt declared in sysemu/cpus.h?) to the
CpusAccel structure of all except TCG.
Similarly for all other methods that are checking non-null-ness of the method
pointer. Perhaps assert non-null for each method in cpus_register_accel().
