2022-02-27dynarmic: Inline exclusive memory accessesmerry
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. See also: merryhime/dynarmic#664
2022-02-21hle: kernel: KSystemControl: Use 6GB memory layout when ↵bunnei
"use_extended_memory_layout" setting is enabled. - This uses a larger 6GB DRAM memory layout, which is useful for some mods that require more memory.
2022-02-21core: hle: kernel: Remove resource limit hack for PhysicalMemory.bunnei
- With prior changes, we now report the correct amount of physical memory available to the emulated process.
2022-02-21core: hle: kernel: KProcess: Pass in KResourceLimit on process creation.bunnei
- This allows us to have a resource limit per process, rather than use the global system resource limit.
2022-02-21core: hle: kernel: KEvent: Pass in owner KProcess on event creation.bunnei
- This is necessary to ensure resource limits are freed from the right process.

KResourceLimit for a process.

Very straightforward, they are just wrappers to the 64-bit version of the SVC.

2022-02-02general: Move deleted copy/move constructor/assignment operators to public ↵Lioncash
interface 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).
2022-02-01hle: kernel: KPageTable: Migrate locks to KScopedLightLock.bunnei
- More accurately reflects real kernel behavior by using guest locks.

that has migrated. - 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.

- But do not enter the priority queue, as otherwise they will be scheduled. - Allows dummy threads to use guest synchronization primitives.

- Considering is_thread_waiting is never set, so we can remove IsThreadWaiting. - KThread::EndWait will take the scheduler lock, so we can remove the redundant lock.
2022-01-20hle: kernel: KThread: Ensure dummy threads never call EndWait.bunnei
- These are only used by host threads for locking and will never have a wait_queue.
