simonb 15a42388c0 In pmap_enter(), sync the instruction cache if VM_PROT_EXECUTE. Fixes
problems when executing programs where text is copied to a page without
a dma sync (like NFS data bcopy'd to a buffer cache page).

From discussion with Jason Thorpe and Eduardo Horvath.

chris 0e7661f023 Update pmap_update to now take the updated pmap as an argument.
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.
