Currently, kprobe-booster is implemented on x86 and x86-64.\nThis is an ia64 port.\n\nOn ia64, kprobe-booster executes a copied bundle directly, instead of single\nstepping. Bundles which have B or X unit and which may cause an exception\n(including break) are not executed directly. And also, to prevent hitting\nbreak exceptions on the copied bundle, only the hindmost kprobe is executed\ndirectly if several kprobes share a bundle and are placed in different slots.\nNote: set_brl_inst() is used for preparing an instruction buffer(it does not\nmodify any active code), so it does not need any atomic operation.\n\nSigned-off-by: Masami Hiramatsu \u003cmhiramat@redhat.com\u003e\nCc: Anil S Keshavamurthy \u003canil.s.keshavamurthy@intel.com\u003e\nCc: Ananth N Mavinakayanahalli \u003cananth@in.ibm.com\u003e\nCc: bibo,mao \u003cbibo.mao@intel.com\u003e\nCc: Rusty Lynch \u003crusty.lynch@intel.com\u003e\nCc: Prasanna S Panchamukhi \u003cprasanna@in.ibm.com\u003e\nCc: Jim Keniston \u003cjkenisto@us.ibm.com\u003e\nCc: Shaohua Li \u003cshaohua.li@intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "45e18c228e131592a922859e1525770a1803191d", "tree": "a971746de55c007d222ef2f7834045261240fffb", "parents": [ "818c7e866f920b145424c2c46deda4b27c3fb316" ], "author": { "name": "Harvey Harrison", "email": "harvey.harrison@gmail.com", "time": "Thu Mar 06 09:49:01 2008 -0800" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Thu Mar 06 09:49:01 2008 -0800" }, "message": "[IA64] kprobes arch consolidation build fix\n\nia64 named their handler kprobes_fault_handler while all other\narches used kprobe_fault_handler.
