From 08ed38b68099f2a492196414b08a7f5dd8dc3537 Mon Sep 17 00:00:00 2001 From: Tony Luck Date: Tue, 14 Nov 2006 09:33:38 -0800 Subject: [IA64] enable trap code on slot 1 Because slot 1 of one instr bundle crosses border of two consecutive 8-bytes, kprobe on slot 1 is disabled. This patch enables kprobe on slot1, it only replaces higher 8-bytes of the instruction bundle and changes the exception code to ignore the low 12 bits of the break number (which is across the border in the lower 8-bytes of the bundle). For those instructions which must execute regardless qp bits, kprobe on slot 1 is still disabled.
