Remove useless casts to volatile ULONG. It doesn't make sense to cast something to volatile, after the pointer is already dereferenced. But we don't need this here anyway.
svn path=/trunk/; revision=52118
Fixes to r52065:
- In IopInterlockedDecrementUlong() and IopInterlockedIncrementUlong(), cast received value to volatile before de/incrementing it so ensure strict ordering with spin locks acquisition.

* Fix several modules to compile with the recent gcc versions.
* ReactOS now compiles with mingw-w64 gcc 4.6.0 and boots to shell.
* Dedicated to dreimer.

Timo Kreuzer:
* Change inline assembly constraint from "r" to "q". "r" means any kind of register, including *si and *di, these cannot be used for 8bit operations on x86, only x64 has sil, dil registers. But gcc is stupid and doesn't get that if we don't tell it explicitly, by using "q", which will only allow a, b, c, d registers. Fixes an assembler error messages that can occur under certain circumstances.

NOTE: Windows does not do this, opting instead to force manufacturers/use pull-up resistors/reconfigure the ARM Bus to map RAM at 0x00000000. For wider portability, I believe it makes more sense to simply do this "trick" in the boot loader.

- Create an empty TRANSPORT_ADDRESS for the local address when doing an implicit bind so TCP/IP can choose its own local port and address instead of trying to bind the remote address and port
- Fixes another critical networking bug
svn path=/trunk/; revision=52092
- Add a Next member to CONNECTION_ENDPOINT to allow multiple connections to be associated with a single address file while not overwriting pointers, dereferencing other people's connection objects, and causing horrific amounts of memory corruption
- Add several sanity checks to prevent this from happening again
- Don't try dereference address files and connection endpoints in the free functions; there should be none associated since r52083 (sanity checks ensure this)
- Don't hold an extra reference to the address file when creating a listener; this reference is implicit
- This should greatly increase reliability of activities that open lots of sockets such as web browsing and running servers on ROS
- This also fixes most issues of not releasing a server port when the listener is closed

- add definition for KeMemoryBarrierWithoutFence
- add x64 version of KeMemoryBarrier and some related defines
- Use KeMemoryBarrierWithoutFence in spinlocks as suggested by Alex
svn path=/trunk/; revision=52079
- Add explicit memory barriers to KxAcquireSpinLock, KxReleaseSpinLock inline functions and KeTryToAcquireQueuedSpinLock, KeTryToAcquireQueuedSpinLockRaiseToSynch in the UP case. This will prevent the compiler from reordering memory access instructions across the boundaries of these functions, even when being inlined.
- Use the inline functions in x64 spinlock functions, too

Hackfix to r52065:
- Comment out call to IopDecrementDeviceObjectRef in IopLoadFileSystemDriver, on Pierre's request. Needs more research. Should fix boot and testcd ASSERT in 2nd stage.
svn path=/trunk/; revision=52075
Fixes to r52065:
- Acquire resources within a critical region
- Simplified IoEnumerateRegisteredFiltersList and made its behaviour match the one described in MSDN: http://msdn.microsoft.com/en-us/library/ff548348%28v=vs.85%29.aspx
