* Perform sanity check before calculating memory available to rump kernel
* Distinguish between 'Hard_context' and 'Hard_context_thread', so no dead
threads (that will not be started) are created
* Install signal-handler for memory-resource requests. This way the fs server
will not block forever when the quota is execeeded and a resource requests
fails, leaving the rump kernels to perform necessary actions
Fixes#1127
Substitute 'swpb' (swap byte) instruction with 'ldrexb/strexb', because 'swpb'
needs to be enabled explicitly by the kernel, which is done by neither HW or FOC.
When disabled, 'swpb' will cause an undefined instruction exception.
Issue #1048
For further information see: http://wiki.netbsd.org/rumpkernel/. In this version
I ported the central rump components to Genode in order to take advantage of
NetBSD file system implementation. The new 'dde_rump' repository contains the
Genode version of the rump libraries and a 'rump_fs' server that implements
Genode file-system-session interface. Currently ext2, iso9660, and fat
file-systems are supported.
