  "message": "[PATCH] x86-64 TIF flags for debug regs and io bitmap in ctxsw\n\nHello,\n\nFollowing my discussion with Andi. Here is a patch that introduces\ntwo new TIF flags to simplify the context switch code in __switch_to().\nThe idea is to minimize the number of cache lines accessed in the common\ncase, i.e., when neither the debug registers nor the I/O bitmap are used.\n\nThis patch covers the x86-64 modifications. A patch for i386 follows.\n\nChangelog:\n\t- add TIF_DEBUG to track when debug registers are active\n\t- add TIF_IO_BITMAP to track when I/O bitmap is used\n\t- modify __switch_to() to use the new TIF flags\n\n\u003csigned-off-by\u003e: eranian@hpl.hp.com\n\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\n",
