From c7173271f3f63738e7ec5a2f074472c5feed3518 Mon Sep 17 00:00:00 2001 From: Tony Luck Date: Tue, 1 May 2012 14:41:35 -0700 Subject: [PATCH] [IA64] Removed "task_size" element from thread_struct - it is now constant When the 32-bit compat code was deleted, we should also have removed the task_size element from the thread structure - threads can only be 64-bit now, so no need to keep track of how much virtual address space each task can have ... everyone gets 0xa000000000000000.
