*** 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.

The broken RNG for ASLR was [[Switch_System_Flaws|fixed]].

===nnSdk===

<code>nn::diag::detail::VAbortImpl</code> when handling the retaddr for storing elsewhere, now uses instruction [https://developer.arm.com/documentation/dui0801/g/A64-General-Instructions/XPACD--XPACI--XPACLRI xpaclri]. PAC instructions are NOPs on ARM hardware which doesn't support it, which includes current NX consoles.

This is likely due to a LLVM [https://reviews.llvm.org/D84502 patch] where xpaclri is now always emitted and not related to actual Armv8.3 hardware.
