- The width parameter in AcpiOsReadPciConfiguration and AcpiOsWritePciConfiguration was in bits but we were treating it as a width in bytes
- This caused overreads, memory corruption, and crashes when these functions were called (VMWare was particularly picky about bad accesses to the PCI configuration space)
- A hack was (unknowingly) added which prevented some crashes but had a side-effect of causing the partial disruption of ACPI's PCI configuration space accesses while the others that went through wrote bad data to the PCI config space or corrupted kernel memory

- Modify some memory types to match what windows uses
- Modify PcMemGetBiosMemoryMap, so that is crops free memory to page alignment, while extending non-free memory to page alignment. This way we don't loose small firmware descriptors like the one for the extended bios data area enumerated by the bios. Fixes a warning from win 2003 about not owned memory.
- Modify MempAddMemoryBlock to map LoaderFirmwarePermanent into kernel space like ntldr, but don't map page 0! ntldr doesn't do that either. Also map LoaderXIPRom.
- After generating memory descriptors from the page lookup table, add any descriptor from the bios memory table, that is higher than MmHigestPhysical address, so we don't loose high rom descriptors. Do not map beyond LoaderPagesSpanned.

- copy ebp into REGS structure on Int386
- Write pointer and size of extended bios data area in physical page 0 location 0x740 and pointers to vga rom fonts in location 0x700. This is required by windows 2003's videoprt. Now freeldr is more Windows 2003 ready then ever!

- Fix auto complete init method based on Wine. Autocomplete shell tests should no longer crash now.
- Brought to you by Claudiu Mihail.

* Implement CDefView::SetCurrentViewMode based on Wine, along with some other bugfixes. Shell32 shlview winetest doesn't crash anymore as a result.

- Introduce two MM_EMPTY_LIST definitions - one for PTE as a whole and one for MMPTE_LIST NextEntry field only and move them to the actual architecture specific headers.
- Implement special pool. This is a special (Capt. Obvious!) kernel pool which is used to catch overruns or underruns, freed memory access and perform additional validation for paged/nonpaged allocations access.

- Do not subclass user32 controls when themes are disabled.This is a temporary hack bacause it turns out that subclassing causes problems. When it is fixed this will be reverted. This change means that in order to make themes work properly, the user has to reboot after enabling.

- Fix memory type for hal and referenced dlls
- Don't allocate the LPB, MADs and all the other stuff from the heap, instead allocate one block of memory for the LPB, extension, etc and strings (fits into one page) and another page for the MADs limit to 200 MADs, 1024 is way over the top)
- Map only those pages into kernel mode, that the kernel will need, this way we don't need to unmap anything later.
svn path=/trunk/; revision=53864
- Fix a typo in HalpAllocPhysicalMemory, that caused the function to remove MADs that still had pages rather than removing those who are empty. Fixes an assertion on VMWare.
Kudos go to Kamil for tracking it down.
- Fix another bug in HalpAllocPhysicalMemory, where the size of the newly allocated MAD was set to the alignment value instead of the original MAD, this lead to conflicting MADs and possible reuse of hal memory by the kernel. This seems to fix a bugcheck 0x19 with halacpi.

- Get rid of MmAllocateMemory, freeing about 1MB of low physical memory for the kernel
- verify that MmMarkPagesInLookupTable is not called with invalid page regions
- add maximum allocation to heap statistics
<long explanation>
There was a function called MmAllocateMemory, what was commented as "// Temporary forwarder..." since January 2008. This function allocated one page of memory and marked it as LoaderOsLoaderHeap. This function was used by the fat filesystem code (and linuxboot.c) which allocated and freed memory in small chunks all the time. Since MmFreeMemory() is not implemented at all (obviously someone removed it) we were allocating one full page for allocations as small as 8 bytes and never free them. This accumulated to a total of 240 pages, almost 1MB, split into into 14 chunks. This memory was never freed by the kernel (the kernel keeps the loader heap memory for some reason) and fragmented the low memory region.
Remove MmAllocateMemory completely and replace references in the fat code with MmHeapAlloc. The maximum heap usage after this was 184 KB, heap size is 4MB.

- In TrackMouseEvent tests, use mouse_event function to move the mouse cause this causes low level hooks to be called and SetCursorPos doesn't
- Test low level mouse hooks for TrackMouseEvent
- Test ways to block WM_MOUSEHOVER and WM_MOUSELEAVE. This is useful to detect where each message is generated
- clean up the code a bit by adding FLUSH_MESSAGES macro that checks for expected message queue status and flushes the message queue
svn path=/trunk/; revision=53855
- Improve tracing
- Fix memory corruption caused by marking pages outside of page lookup table (when table is allocated only free pages was counted but MmMarkPagesInLookupTable was used for all types of memory like firmware). Fixes bugcheck in ACPI HAL which happened for me

- Undo disabling of systemcalls, which was disabled in r53646 for testing purpose.
- Sillence "Support for SYSENTER detected." debug print, since its the normal case, only keep the disabled and not present cases.
- Silence "xxx support detected but not yet taken advantage of" debug prints. CPU features are already reported and there is no point in printing every single feature we do not support.
- Invert if/else in KiRestoreFastSyscallReturnState

Add FREELDR_MEMORY_DESCRIPTOR structure using TYPE_OF_MEMORY instead of
MEMORY_TYPE. Use it in place of MEMORY_DESCRIPTOR. Undo r53837 changes.

* Add _dbg versions of freeldr_pe and setupldr_pe per Dmitry's request. They retain debug info, and they're compiled on-demand (not included in the normal build).

Fix wrong behavior of the "native applications startup at boot time" feature in SMSS.
Modifications:
- Added missing buffer allocation checks.
- Check for presence of default path.
- Minor clean-ups.
- Fix bad indentation/coding style.
Original patch by Hermès BÉLUSCA.
See issue #6180 for more details.

- Cleanup amd64 mm.h header
- Call MiScanMemoryDescriptors earlier, since it doesn't depend on anything except the loader block.
- MiComputeColorInformation() and the calculation of the pfn database size are portable, so move them out of MiInitMachineDependent
