== svcUnmapMemory ==
'''Description:''' Unmaps a region that was previously mapped with [[#svcMapMemory]].
It's possible to unmap ranges partially, you don't need to unmap the entire range "in one go".
The srcaddr/dstaddr must match what was given when the pages were originally mapped.

== svcCreateThread ==
'''Description:''' Create a thread in the current process.
Processor_id must be 0,1,2,3 or -2, where -2 uses the default cpuid for process.
