With introduction of 74e527b, a330b56 and subsequently 2791ecd ReactOS can now properly set IOPL (I/O privilege level) for user mode trusted processes. With that said, enable the compilation of raise hard error function call code back.
ProcessUserModeIOPL is strictly implemented for 32-bit architecture so it doesn't make any sense for CSRSS to gather user mode I/O privilege when that won't work anyway.
ProcessUserModeIOPL, ProcessWow64Information and ThreadZeroTlsCell classes fail on AMD64 build because of wrong IQS values assigned to them. Also explicitly tell the compiler that ProcessUserModeIOPL is strictly for x86 as user mode I/O privilege level is 32-bit stuff.
In addition to that, implement IQS_NO_TYPE_LENGTH macro which it'll be used for classes such as ProcessUserModeIOPL where type length is not required and that it should be 0. With that said, we indirectly fix a size length mismatch issue with ProcessUserModeIOPL on 32-bit of ReactOS as well.
Do not use custom alloc/free functions by default.
Do not free resources at process exit.
- You're doing it brick by brick while the OS & CRT do that with a bulldozer better than you do.
Enter an SEH2_TRY one time and do all testing within it instead of entering the SEH_TRY multiple times.
The commit is an addendum to 0.4.15-dev-2734-g 514147776a

This is 1:1 the final approved content of #3758, but I committed
by hand and closed the PR to avoid squash+rebase.
Spinlocks are not reentrant (and this is done a lot), using them forces us to have
an horrible hack in the kernel, which unschedules threads which are at DISPATCH_LEVEL
thus allowing another thread to take ownership of the spinlock while the unscheduled
thread should already hold it.

This speeds up boot a bit and also decreases binary size.
- Introduce a new CMake define ISAPNP_ENABLE that defined only in x86 platform
when ISA PnP is supported.
Rework the hardware support code to avoid unneeded transitions
between configuration states.
- Only call WaitForKey when needed.
- Each PnP state transition causes the bus to move to WaitForKey state.
Besides, deactivate logical device during processing remove request.
- Fix empty resource descriptors being created.
- Properly support IRQ descriptors.
- Introduce four helpers made to help search descriptors
in the logical device's requirements.
- Implement support for memory descriptors and alternative configurations.
- DMA descriptors are always DMA_8.
- Support all resource descriptors.
- Optimize card identification.
- Detect cards that is no longer present on the bus.
- Deactivate cards after the identification phase; they will be activated
by start device IRP.
- Provide a device description and compatible IDs to the device manager.
- Prevent duplicate IDs across multiple logical devices.
- Suppress warning about the usage of literals in port addresses.
- Implement device removal.
- Finish the Read Port special handling
introduced in 21514e473f.
- Gracefully handle low memory situations.
- Implement IRQ translator.
- Correctly stub power IRP handling.
- Remove unneeded dispatch routines; implement WMI IRP handling.
- Do not handle requests like WRITE_CONFIG.
- Add a signature member to device extensions to make checks clearer.
This PDO is created only once during start of first FDO.
Other buses will remain in an inactive state until
the first FDO receives a remove request.
