From be318c0f38b6b72a0716edce818b755411e75600 Mon Sep 17 00:00:00 2001 From: Sergey Bugaev Date: Sat, 18 Feb 2023 23:37:14 +0300 Subject: mach: Use PAGE_SIZE The PAGE_SIZE from the Mach headers statically defines the machine's page size. There's no need to query it dynamically; furthermore, the implementation of the vm_statistics () RPC unconditionally fills in pagesize = PAGE_SIZE; Not doing the extra RPC shaves off 2 RPCs from the start-up of every process!
