Benjamin Herrenschmidt 370a908db1 [POWERPC] DEBUG_PAGEALLOC for 64-bit Here's an implementation of DEBUG_PAGEALLOC for 64 bits powerpc. It applies on top of the 32 bits patch. Unlike Anton's previous attempt, I'm not using updatepp. I'm removing the hash entries from the bolted mapping (using a map in RAM of all the slots). Expensive but it doesn't really matter, does it ? :-) Memory hot-added doesn't benefit from this unless it's added at an address that is below end_of_DRAM() as calculated at boot time.
