Richard Yao b68503fb30 Remove vmem_size() consumers ... There are currently three vmem_size() consumers all of which are part of the ARC implemention. However, since the expected behavior of the Linux and Solaris virtual memory subsystems are so different the behavior in each of these instances needs to be reevaluated. * arc_evict_needed() - This is actually dead code. Arena support was never added to the SPL and zio_arena is always NULL. This support isn't needed so we simply remove this dead code. * arc_memory_throttle() - On Solaris where virtual memory constitutes almost all of the address space we can reasonably expect there to be a fairly large amount free. However, on Linux by default we only have about 100MB total and that's heavily used by the ARC. So the expectation on Linux is that this will usually be a small value. Therefore we remove the vmem_size() check for i386 systems because the expectation is that it will be less than the zfs_write_limit_max. * arc_init() - Here vmem_size() is used to initially size the ARC. Since the ARC is currently backed by the virtual address space it makes sense to use this as a limit on the ARC for 32-bit systems. This code can be removed when the ARC is backed by the page cache.
