create for each task an interrupt stack table (IST1)
...
Currently, "user-level" code has to deactivate the red zone support.
To avoid this, we create an interrupt stack table (IST1), which is
the default stack for all interrupts. Consequently, the common stack
isn't touch by handling any interrupt and the red-zone could be used
for compiler optimizations.
By using IST1, nested interrupts (beside NMI) arn't longer supported.
But HermitCores doesn't rely on this support.

xray: conditionally forward compiler/linker flags to enable xray profiling
...
You have to set the variable PROFILING to something to enable profiling using
Xray. In order for profiling code to be compiled into the runtime and demo
applications you must clean the whole project before.
Example:
$ cd HermitCore
$ make clean
$ make PROFILING=yes
Hint: You can also export the variable (`export PROFILING=yes`) for a more
permanent configuration.
