We seemed to have missed a few corner cases in commit f6c137ff ("KVM: s390: randomize sca address"). The SCA has a maximum size of 2112 bytes. By setting the sca_offset to some unlucky numbers, we exceed the page. 0x7c0 (1984) -> Fits exactly 0x7d0 (2000) -> 16 bytes out 0x7e0 (2016) -> 32 bytes out 0x7f0 (2032) -> 48 bytes out One VCPU entry is 32 bytes long. For the last two cases, we actually write data to the other page. 1. The address of the VCPU. 2. Injection/delivery/clearing of SIGP externall calls via SIGP IF. Especially the 2. happens regularly. So this could produce two problems: 1. The guest losing/getting external calls. 2. Random memory overwrites in the host. So this problem happens on every 127 + 128 created VM with 64 VCPUs.

Let's factor this out and always use get_tod_clock_fast() when reading the guest TOD. STORE CLOCK FAST does not do serialization and, therefore, might result in some fuzziness between different processors in a way that subsequent calls on different CPUs might have time stamps that are earlier. This semantics is fine though for all KVM use cases. To make it obvious that the new function has STORE CLOCK FAST semantics we name it kvm_s390_get_tod_clock_fast. With this patch, we only have a handful of places were we have to care about STP sync (using preempt_disable() logic).

Let's move that whole logic into one function. We now always use unsigned values when calculating the epoch (to avoid over/underflow defined). Also, we always have to get all VCPUs out of SIE before doing the update to avoid running differing VCPUs with different TODs.

Nobody except early.c makes use of store_tod_clock() to handle the cc. So if we would get a cc != 0, we would be in more trouble. Let's replace all users with get_tod_clock(). Returning a cc on an ioctl sounded strange either way. We can now also easily move the get_tod_clock() call into the preempt_disable() section. This is in fact necessary to make the STP sync work as expected. Otherwise the host TOD could change and we would end up with a wrong epoch calculation.

PER events can always co-exist with other program interrupts. For now, we always overwrite all program interrupt parameters when injecting any type of program interrupt. Let's handle that correctly by only overwriting the relevant portion of the program interrupt parameters. Therefore we can now inject PER events and ordinary program interrupts concurrently, resulting in no loss of program interrupts. This will especially by helpful when manually detecting PER events later - as both types might be triggered during one SIE exit.

The main reason to keep program injection in kernel separated until now was that we were able to do some checking, if really only the owning thread injects program interrupts (via waitqueue_active(li->wq)). This BUG_ON was never triggered and the chances of really hitting it, if another thread injected a program irq to another vcpu, were very small. Let's drop this check and turn kvm_s390_inject_program_int() and kvm_s390_inject_prog_irq() into simple inline functions that makes use of kvm_s390_inject_vcpu(). __must_check can be dropped as they are implicitely given by kvm_s390_inject_vcpu(), to avoid ugly long function prototypes.
