- Boots to blue screen with white text to indicate checkpoint.
- More cleanup/work needed.
- Will post Wiki on testing info soon.

[NTOS]: Rework the way traps with possibly dirty DS/ES segments are handled. The FAST V86 hack is gone. Intead, created a "safe" version of IsTrapV86 and IsTrapUser that does an SS segment dereference (known good). The condition is then based on this, and the segments are saved and loaded safely. Note that for GCC 4.5 the ASM can be improved to directly branch or not to a label, instead of returning a boolean that is then further compared before branching.
This will fix certain exceptions that were seen in KeUpdateSystemTime, and might fix the sneaking HalpTrap0D while not in V86 mode (no promises).

- Hackfix corruption of audio buffer list which made the playback thread spin forever on an already played buffer.
- Tested with Winamp / VLC / mplay32 with Vbox 3.1.2
svn path=/trunk/; revision=45360
- Use silence buffer when no audio buffers are available. Replaces the endless disturbing sound loop.
- Sound still broken

[NTOS]: Fix KiEnterInterruptFrame. In the case of a V86 trap, the segments were overriden because this wasn't a kernel trap (missing if/elseif).

[HAL]: Implement support for Level interrupts, which are used by certain EISA cards, and more particularly, all PCI hardware. Level interrupts were not previously handled correctly, being treated as edge/latched interrupts instead.
[NTOS/HAL]: Remove VDM Alert KPCR hack (which was buggy). Now the PKTRAP_FRAME is passed as a parameter to HalpEndSoftwareInterrupt/HalEndSystemInterrupt. This also removes the HalpNestedTrap ASM hack, since the call can now be done in C.
[PERF]: On real machines, writing the PIC mask is a relatively expensive I/O operation, and IRQL lower/raise can happen hundreds of times a second. Lazy IRQL provides an important optimization.
[PERF]: Correctly handling level interrupts as level interrupts allows for faster, and more efficient, IRQ handling.

- DejaVu Sans Mono seems to have a bug which makes Windows and Arwinss report double max char width as compared to a real char width. Since only a monospace font could be used, measure exact char width using GetTextExtentPoint32W and use that value.
svn path=/trunk/; revision=45319
[NTOS]: Remove thousands of lines of assembly that are not needed anymore.
[NTOS]: Put all interrupt code in irqobj.c (platform-specific).
[NTOS]: DPC Interrupt is really the thread scheduler interrupt (DPC work happens in C), which mostly does contexts switching and scheduling decisions, so move it to ctxswitch.S

- Make ValidateRect a direct call, update related. Update UpdateWindow and some code sorting. Getting ready for WND switch.
svn path=/trunk/; revision=45307
[NTOS]: Implement KiUnexpectedInterruptTail and KiUnexpectedInterrupt in C as well.
This is [PERF] too since the C interrupt handling code is a lot more efficient than the ASM one. Numbers look good here.

[DDK]: KeGetCurrentProcessorNumber should not return a 32-bit DWORD combined of "ProcessorNumer", "VdmAlert" and "SecondLevelCacheAssociativity" because those 3 fields are probably not equal to a processor number. Having an L2 Cache will no longer result in ReactOS believing you have a 32000 core CPU.
svn path=/trunk/; revision=45299
- Added -P Pipeline option for Powershell support, see below
- Renaming some structs to avoid potential naming conflicts with windows.h
- stdin/out -> stdIn/Out for redirecting
- Fixed potential mem leak
- A little more tracing and cleanup
Updated piperead (Jan Roeloffzen) Bug 5146
- Added Pipe client function, based on msdn example
- Improved option handling (try piperead -h)
- logging, error handling
- Integrated in build (pipetools.mak)

[NTOS]: Enable V8086 Fast-V86 Trap mode for Trap 6 (Invalid Opcode). Because we are now taking zero traps during V8086 mode, we can't do the "BOP lookahead", so the only trap we do get is when we hit the BOP/invalid opcode itself.
[NTOS]: Multiple fixes to V8086 opcode emulation code that I noticed while looking through the source. Also multiple fixes to VDM code.
This change will only impact real hardware and VMWare, since QEMU does not support VME. On VMWare, performance increased up to 400% during bootup (80 million cycles instead of 300 million, in one test).
