This commit resynchronised to the state in Linux commit 598bae70c2a8e35c8d39b610cca2b32afcf047af. Differences from upstream: find_cpio_data is __init, printk instead of pr_*. This appears to fix Debian bug #785187. "Appears" because my test box happens to be AMD and the issue is that the (valid) cpio generated by the Intel ucode is not liked by the old Xen code. I've tested by hacking the hypervisor to look for the Intel path.

However, in all cases where the "while (len)" loop executed twice, data corruption would occur as the second memcpy() starts from the beginning of "data" again, rather than from where it got to. This bug manifested itself as protocol corruption when a reply header crossed the first wrap of the response ring. However, similar corruption would also occur if hvmloader observed xenstored performing partial writes of the block in question, or if hvmloader had to wait for xenstored to make space in either ring.

In Credit1, we fail at this, because of how we use cpupool_scheduler_cpumask(). In fact, for a free pCPU, cpupool_scheduler_cpumask() returns a pointer to cpupool_free_cpus, and hence, near the top of csched_load_balance(): if ( unlikely(!cpumask_test_cpu(cpu, online)) ) goto out; is false (the pCPU _is_ free!), and we therefore do not jump to the end right away, as we should. This, causes the following splat when resuming from ACPI S3 with pCPUs not assigned to any pool: (XEN) ----[ Xen-4.6-unstable x86_64 debug=y Tainted: C ]---- (XEN) ... ... ...

SEDF is in a similar situation, so fix it too. Still in Credit1, we must make sure that free (or offline) CPUs are not considered "ticklable". Not doing so would impair the load balancing algorithm, making the scheduler think that it is possible to 'ask' the pCPU to pick up some work, while in reallity, that will never happen! Evidence of such behavior is shown in this trace: Name CPU list Pool-0 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14 0.112998198 | ||.|| -|x||-|- d0v0 runstate_change d0v4 offline->runnable ] 0.112998198 | ||.|| -|x||-|- d0v0 22006(2:2:6) 1 [ f ] ] 0.112999612 | ||.|| -|x||-|- d0v0 28004(2:8:4) 2 [ 0 4 ] 0.113003387 | ||.|| -||||-|x d32767v15 runstate_continue d32767v15 running->running where "22006(2:2:6) 1 [ f ]" means that pCPU 15, which is free from any pool, is tickled. The cure, in this case, is to filter out the free pCPUs, within __runq_tickle().
