Subject: [PATCH] Fix PR19990 by updating runtime/linux/access_process_vm.h.
* runtime/linux/access_process_vm.h (__access_process_vm_): Use
get_user_pages_remote() when available.
* buildrun.cxx (compile_pass): Added export test for
'get_user_pages_remote()'.

Subject: [PATCH] Fix PR20132 by updating the runtime to handle a 'struct inode' change.
* runtime/transport/transport.c (_stp_lock_inode): Use the new inode
lock/unlock routines.
(_stp_unlock_inode): Ditto.
* buildrun.cxx (compile_pass): Add autoconf-inode-rwsem test.
* runtime/linux/autoconf-inode-rwsem.c: New 'autoconf' test.

Subject: [PATCH] Fix PR20158 by updating the runtime for the 4.6 kernel.
* buildrun.cxx (compile_pass): Added autoconf-stacktrace_ops-int-address.c
compile test.
* stack.c: (print_stack_address): If STAPCONF_STACKTRACE_OPS_INT_ADDRESS
is defined, the function returns a int instead of being a void
function.
* runtime/linux/autoconf-stacktrace_ops-int-address.c: New autoconf-style
test.
