  "message": "[IA64] fix personality(PER_LINUX32) performance issue\n\nThe patch aims to fix a performance issue for the syscall\npersonality(PER_LINUX32).\n\nOn IA-64 box, the syscall personality (PER_LINUX32) has poor performance\nbecause it failed to find the Linux/x86 execution domain. Then it tried\nto load the kernel module however it failed always and it used the default\nexecution domain PER_LINUX instead. Requesting kernel modules is very\nexpensive. It caused the performance issue. (see the function\nlookup_exec_domain in kernel/exec_domain.c).\n\nTo resolve the issue, execution domain Linux/x86 is always registered in\ninitialization time for IA-64 architecture.\n\nSigned-off-by: Xiaolan Huang \u003cxiaolan.huang@intel.com\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n",
