Module Name:    src
Committed By:   jdolecek
Date:           Sat May 19 11:39:37 UTC 2018

Modified Files:
        src/sys/arch/x86/include: pmap.h
        src/sys/arch/x86/x86: pmap.c
        src/sys/kern: kern_synch.c sys_pipe.c
        src/sys/sys: pipe.h
        src/sys/uvm: files.uvm uvm_extern.h uvm_init.c
Removed Files:
        src/sys/uvm: uvm_emap.c

Log Message:
Remove emap support. Unfortunately it never got to state where it would be
used and usable, due to reliability and limited & complicated MD support.

Going forward, we need to concentrate on interface which do not map anything
into kernel in first place (such as direct map or KVA-less I/O), rather
than making those mappings cheaper to do.
