			* Support was added for loading non-KIP processes into the Secure pool via a flag in SvcCreateProcess.
			** This is used by only for es, to prevent attackers from using GPU DMA to take over the es sysmodule to pirate games.
			** Correspondingly, the KHeapArrange calculation of the secure pool size now has an extra 0x13A000 factored in (to ensure there is enough space for es).

	* New synchronization syscalls 0x34, 0x35 added.		* New synchronization syscalls 0x34, 0x35 added: These ones allow implementation of synchronization primitives without a mutex+condvar pair. This is more efficient because when a thread wakes up from a condvar, the mutex is held and needs to perform a syscall to unlock it. If you have N threads blocking on a condvar, you need N-1 syscalls to wake all the threads. With the new syscalls, you can wake up all N with a single syscall.

	* Added new syscall svcDumpInfoNew, but it's stubbed.		* Added new syscall svcDumpInfoNew, but it's stubbed.

			* Kernel startup code was updated:
