that actually contained the address space itself (so it wasn't part of any process). Its locks however, were associated to the "current process", which, when this function is called, is the idle process (which later is cloned into the initial system process). Shortly thereafter, the address space of the "current process" (still, at this point, the idle process) was initialized with the function reserved for real processes (MmInitializeProcessAddressSpace), which among other things, performed a couple of user-mode mappings (which are irrelevant and should not be part of the system process address space). This created a weird schism: the kernel address space was actually a global variable associated with no process at all, while the kernel process had its own address space as well (which was not the kernel address space). It's a miracle this didn't screw anything up especially since whether or not the address space has an owner determined the lowest address (which means that if the kernel process allocated a memory with its *own* address space, the code would think it was a user-mode process). This patch gets rid of the kernel address space as a static structure, and instead makes it a pointer into the idle/system process' address space. It also gets rid of MmInitializeKernelAddresSpace and instead makes use of the existing MmInitializeHandBuiltProcess, cleaning up the user-mode allocations previously made. Even though all address spaces now have an owner and are part of a process, MmGetAddressSpaceOwner will still return NULL for now, to remain backwards compatible with legacy code. svn path=/trunk/; revision=34876 |
