cache_loongson3.c

Some implementations of HitSyncDCache() call pmap_extract() for va->pa conversion. Because pmap_extract() acquires the PTE mutex, a "locking against myself" panic is triggered if the cache routine gets called in a context where the mutex is already held.

Normally context switches happen in mi_switch() but there are 3 cases where a switch happens outside. Cleanup these code paths and make the machine independent.

The sigtramp was calling sigreturn(2), and upon failure exit(2), which doesn't make sense anymore. It is better to just issue an illegal instruction. ok kettenis, with some misgivings about inconsistant approaches between architectures. In the future we could change sigreturn(2) to never return an exit code, but always just terminate the process. We stopped this system call from being callable ages ago with msyscall(2), and there is no stub for it in libc.. maybe that's the next step to take?

All the device and file type ioctl routines just ignore FIONBIO, so stop calling down into those layer from fcntl(F_SETFL) or ioctl(FIONBIO) and delete the "do nothing for this" stubs in all the *ioctl routines.

Fix TLB size computation on OCTEON II and III. The CPUs have utilized the whole TLB space even before this. However, TLB initialization on boot and TLB flush on ASID wraparound have been incomplete. These have caused crashes of processes.
