tsutsui 7cb169d2dd Disable sosend_loan() in sys/kern/uipc_socket.c temporarily on CPUs
which have virtual address indexed cache and whose pmaps don't always
allow normal shared mappings even for read only pages.

In future, these pmaps should be rewritten to handle such read only
shared mappings properly like ARM pmap, but currently we just disable
sosend_loan() to avoid unnecessary uncached mappings and cache flushes
on MIPS3 CPUs, or map/unmap thrashing on SH4.

Discussed with thorpej a while ago.
