b38fee2867 L4Linux stability improvements
- search for alternative virtual address regions upwards, starting from
  the given start address, in the 'l4re_rm_attach()' and
  'Region_manager::reserve_range()' functions

- don't treat memory locations above 0x80000000 in l4linux's virtual
  address space as device memory

- align the start address of the vmalloc area according to the assumption
  in 'devicemaps_init()'

Fixes #414.

f4e0230dde L4lx: mask all VCPU IRQs when doing ipc (fix #553)
Open VCPU interrupts while the VCPU is in an IPC operation can badly influence
its state. That's why this commit fixes a whole bunch of places, where IRQs
weren't masked by now.

518cbc5a5f L4Linux: no linux-kernel memcpy in cxx (fix #446)
Certain symbols from the libgcc_eh library in cxx that is linked with the
L4Linux kernel were resolved by using kernel internal implementations.
This lead to errors because the complete Linux kernel is built regparm=3.
This patch prefixes the appropriate symbols in the Linux Kernel and its
modules. Moreover, it fixes some warnings introduced by the latest update
to gcc 4.7.

760f37fc86 Fiasco.OC: enable SMP for L4Linux
This commit comprises the following changes to enable L4Linux to use several
CPUs:
* change default configuration for x86 and ARM
* add atomic cmpxchg operation to l4re library
* implement l4_sleep (per thread)
* enable setting affinity for VCPUs and IRQs
* move "per CPU" section within linker-script (x86 only)
* introduce SMP run-script for pandaboard
* deactivate direct scheduler (Fiasco.OC syscall) access by L4Linux
