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.
Make calls using IPCs IRQ safe, handle packet exhaustion, removed
'Packet_pool', tweak TCP rmem and wmem buffer sizes to show better performance
results, use 'Net::Packet_allocator, fix 'update-patch' Makefile command
