- Instead of randomization, choose in-order addresses for where to map NROs into memory.
- This results in predictable behavior when debugging and consistent behavior when reproducing issues.
- This makes these functions more accurate to the real HOS implementations.
- Fixes memory access issues in Super Smash Bros. Ultimate that occur when un/mapping NROs.
- Updates the KMemoryManager implementation against latest documentation.
- Reworks KMemoryLayout to be accessed throughout the kernel.
- Fixes an issue with pool sizes being incorrectly reported.
Inlines implementation of exclusive instructions into JITted code,
improving performance of applications relying heavily on these
instructions.
We also fastmem these instructions for additional speed, with
support for appropriate recompilation on fastmem failure.
An unsafe optimization to disable the intercore global_monitor is also
provided, should one wish to rely solely on cmpxchg semantics for
safety.

This warning is triggered by GCC when copying into non-trivially default constructible types, as it uses the more restrictive std::is_trivial (which includes std::is_trivially_default_constructible) to determine whether memcpy is safe instead of std::is_trivially_copyable.
This allows for better compiler errors, where the compiler will state a
copy or move couldn't occur due to the relevant function being deleted.
Previously a compiler would warn about the relevant function not being
accessible (which, while true, isn't as informative as it could be).
- Previously, it was possible for a thread migration to occur from core A to core B.
- Next, core B waits on a guest lock that must be released by a thread queued for core A.
- Meanwhile, core A is still waiting on the core B's current thread lock - resulting in a deadlock.
- Fix this by try-locking the thread lock.
- Fixes softlocks in FF8 and Pokemon Legends Arceus.
