Andriy Gapon 0b750af1b1 amd64: reduce VM_KMEM_SIZE_SCALE to 1 allowing kernel to use more memory 
KVA space is abundant on amd64, so there is no reason to limit kernel
map size to a fraction of available physical memory.  In fact, it could
be larger than physical memory.

This should help with memory auto-tuning for ZFS and shouldn't affect
other workloads.
This should reduce number of circumstances for "kmem_map too small"
panics, but probably won't eliminate them entirely due to potential kmem
fragmentation.

In fact, you might want/need to limit maximum ARC size after this commit
if you need to resrve more memory for applications.

This change was discussed on arch@ and nobody said "don't do it".
