01/01: [NTOS:MM] Fix ViewSize parameter passed to MiInsertVadEx() from MiCreatePebOrTeb() The size is in bytes, not in pages! On x86 we got away with it, since PEB and TEB require only a single page and the 1 passed to MiInsertVadEx() was aligned up to PAGE_SIZE. On x64 this doesn't work, since the size is 2 pages.

    [NTOS:MM] Fix ViewSize parameter passed to MiInsertVadEx() from MiCreatePebOrTeb()
    The size is in bytes, not in pages! On x86 we got away with it, since PEB and TEB
require only a single page and the 1 passed to MiInsertVadEx() was aligned up to
PAGE_SIZE. On x64 this doesn't work, since the size is 2 pages.
