From 96651896b8d9ad4244a1c3ed9691faa3e382f503 Mon Sep 17 00:00:00 2001 From: Xiantao Zhang Date: Thu, 3 Apr 2008 11:02:58 -0700 Subject: [IA64] Add API for allocating Dynamic TR resource. Dynamic TR resource should be managed in the uniform way. Add two interfaces for kernel: ia64_itr_entry: Allocate a (pair of) TR for caller. ia64_ptr_entry: Purge a (pair of ) TR by caller.
