*** KMemoryState_Io now supports the CanAlignedDeviceMap and CanDeviceMap flags.

*** KPageTableBase::GetContiguousMemoryRangeWithState no longer checks that the passed memory address is heap.

**** KPageTable::MemoryRange now tracks whether the range is reference counted, and Close() only closes the pages if they are.

*** KPageTableBase::OpenMemoryRangeForMapDeviceAddressSpace no longer checks passes KMemoryState_FlagReferenceCounted.

*** KPageTableBase::LockForMapDeviceAddressSpace takes two new arguments, an output bool * to write whether the state was io, and a bool for whether to check KMemoryState_FlagReferenceCounted.

Line 149:

Line 150:

*** When a process is created with system resource size > 0, it now creates a KSecureSystemResource (which manages allocation with KSystemControl).

**** All actual underlying logic is the same, this just abstracts the KSystemControl/secure memory interaction out of KProcess.

* KPageTable::MemoryRange now tracks whether the range is reference counted, and Close() only closes the pages if they are.

* KInterruptEventTask was removed and no longer exists.

** KInterruptEvent now inherits from KInterruptTask directly.

Besides the various IPC changes, ~~a vulnerable func was~~ [[Switch_System_Flaws|fixed]].

Besides the various IPC changes, security flaws were [[Switch_System_Flaws|fixed]].
