7 dayskernel: Prevent physmem clobbers + zero memoryIan Moffett
To prevent a situation where there is a data race between one thread freeing physical memory and one allocating physical memory. Do not immediately reuse freed physical memory. Instead, keep allocating upwards and once there is no more room, wrap the last_idx back to the bitmap free index. We now also zero allocated physical memory for security reasons.
