Avoids the need to have per IRQ a thread that blocks synchronously for next
interrupt. Now a thread may wait for multiple IRQs as other signals
simultaneously.
In core no threads are required anymore for IRQs/MSI - the clients (either
the pci_drv or in case of MSI the driver) gets the IRQ delivered directly as
a ordinary Genode signal.
Useful since #1216 and #1487 is now available.
Commit applies feature of #1446 also to IRQ/MSIs.
The bindings for 32bit did not consider that in the syscall_3 function
edx changes due to the assembly instructions and that in the syscall_4
function edx and ecx change. So, the compiler wrongly assumed that the
content of these registers stayed unchanged.
Fixes#1447
This patch changes the top-level directory layout as a preparatory
step for improving the tools for managing 3rd-party source codes.
The rationale is described in the issue referenced below.
