e720764a9b Sigma0: raise sigma0's priority to maximum.
When sigma0 runs on a lower priority than the rest of the threads in the system
it might come to the point that while answering a page fault or I/O memory area
request the timeslice of the caller (core-pager) gets fully consumed. As long as
other threads are still executable and don't block sigma0 won't do progress
anymore, because it runs at the lowest priority.  This commit simply sets
sigma0's priority to the highest in the system.

Was: 'sigma0_prio.patch'

3cae95ac84 Fiasco.OC: fix io-port fault answer in sigma0
In sigma0 normally no answer tag to a request/fault is created. It
simply uses the message tag received with the request. This doesn't work out
when I/O ports are requested. This patch constructs an appropriate answer tag.
Moreover, we have to enable I/O port protection in the kernel configuration.

9f2115ee41 JBD: Increase name buffer to 32K
Increase the size of the JDB kernel object names buffer. The original size was
too small for some Genode scenarios and caused missing thread names in the
kernel debugger thread list.

2e9923b4fd Caps: fix l4_task_cap_equal semantic.
The syscall l4_task_cap_equal almost returns false although the referenced
kernel-objects are equal. This patch changes the semantic of the syscall so that
whenever two capabilities refering the same kernel-object are compared it will
return true. Please refer to the discussion of the following mail thread:
