daf557b245 [RTL/x64] Fix a bug in RtlpUnwindInternal 
Check if the stack pointer is out of bounds, before trying to unwind a frame. This will not fix any crashes, but it prevents simple crashes from going into a recursive exception.

a438d7c3b8 [UCRT] Add GCC compatible definition of _CRT_STDIO_INLINE 
In C99 mode GCC emits global symbols for inline functions, as soon as the compilation unit contains a declaration that marks the function as "extern". A number of functions like printf are implicitly declared as extern by GCC, which seemingly cannot be disabled. This would lead to the inline function being emitted as a global symbol in every compilation unit. Using static inline prevents duplicate symbol errors.

70bf3bb8fa [NTOS:KDBG] Add back 'cregs' command 
This command was removed in commit baa47fa5e0
because there was no way to get the CRx registers from a CONTEXT structure.
Previous code was also displaying current GDTR/LDTR and IDT.

Rewrite the code to use KdSystemDebugControl(SysDbgReadControlSpace, ...)
to get CRx, GDTR/LDTR and IDT values just before entering debugger.

Revert "[NTUSER] Enable SM_CXICON etc. settings from registry (#7679)" (#7682) 
This reverts commit 3b3741c10a of #7679 .
It seems like the shell icon size is not the
system icon size.

The wide string L"Shell Small Icon Size" is detected in
shell32.dll and themeui.dll.
No L"Shell Small Icon Size" in win32k.sys found.
JIRA issue: CORE-12905

[NTUSER] Enable SM_CXICON etc. settings from registry (#7679) 
Improve usability.
JIRA issue: CORE-12905
- Add nIconSize and nSmallIconSize
  values to SPIVALUES structure.
- Load "Shell Icon Size" and "Shell
  Small Icon Size" values from registry.
- Enable changing of SM_CXICON,
  SM_CYICON, SM_CXSMICON, and
  SM_CYSMICON settings.

[ACPI] Move CMBATT and COMPBATT out of the acpi directory (#7599) 
Move these out of ACPI in preparation for ACPI_NEW so they keep their juicy commit history.
Also both ACPIs can coexist for awhile as I don't see the old driver getting removed anytime soon.

[NTOS:EX] HACK: on livecd, disable security features in NtSystemDebugControl 
WinDBG can do some local debugging using 'windbg -kl'. In that case,
WinDBG tries to directly use NtSystemDebugControl. If this function
returns an error, WinDBG extracts a driver from its resources.
WinDBG will send IOCTLs to this driver, and this driver will call
KdSystemDebugControl.

However, on livecd (where %SYSTEMROOT% is read-only), WinDBG is unable
to extract the driver from its resources, and can't use the driver to
call KdSystemDebugControl.

As a work-around, allow all control classes in NtSystemDebugControl
in case of livecd.
WinDBG local debugging now also works on livecd (windbg -kl).

[NTOS:KD64] Fix freezes on first chance exception when KDBG is enabled and KdIgnoreUmExceptions is TRUE 
This fixes the following use case:
- Execute 'kdbgctrl.exe -du'
- Execute 'kdbgctrl.exe -cu'
- See that last command never finishes
