Remove the incomprehensible PFN allocation being done for the pages holding the page list array. We now: 1) Find the highest usable RAM page 2) Allocate the PTEs to hold the array from that point on and lower. Don't do expensive divisions for every single page on the system being looped! Precompute the values ONCE. Don't set the reference count for the KPCR and KUSER_SHARED_DATA to 0, these are LIVE pages! Removed the hack which pre-initializes the balancer -- this isn't needed anymore since the initial PTEs are allocated always from RAM now. Add some comments about the assumptions being made in this code regarding all PCs having the same kind of memory maps. svn path=/trunk/; revision=32357 |
