1. A computer system comprising: a plurality of processor cores each configured to initiate access requests to a system memory by providing a physical address; and a first cache subsystem including a cache memory, wherein the cache subsystem is shared by each of a first subset of the plurality of processor cores; and wherein, responsive to receiving a memory access request from one of the first subset of the plurality of processor cores, the first cache subsystem is to configured to: determine if a physical address of the memory access request is in a first paged region of memory with respect to the first subset of the plurality of processor cores; and access a set of page attributes for a page corresponding to the physical address from a page attribute table responsive to determining that the physical address is within the first paged region, wherein the page attribute table is shared by each of the first subset of the plurality of processor cores.
