New Revision: 53057
URL: http://svn.reactos.org/svn/reactos?rev=53057&view=rev
Log:
[KERNEL32]: Cleanup GetSystemInfo and friends, fix some bugs, mainly removing
support for unsupported CPUs/architectures, and adding support for
PROCESSOR_ARCHITECTURE_AMD64. Did some refactoring to support WoW64 in the
future as well.
