      "message": "gcov: add gcov profiling infrastructure\n\nEnable the use of GCC\u0027s coverage testing tool gcov [1] with the Linux\nkernel.  gcov may be useful for:\n\n * debugging (has this code been reached at all?)\n * test improvement (how do I change my test to cover these lines?)\n * minimizing kernel configurations (do I need this option if the\n   associated code is never run?)\n\nThe profiling patch incorporates the following changes:\n\n * change kbuild to include profiling flags\n * provide functions needed by profiling code\n * present profiling data as files in debugfs\n\nNote that on some architectures, enabling gcc\u0027s profiling option\n\"-fprofile-arcs\" for the entire kernel may trigger compile/link/\nrun-time problems, some of which are caused by toolchain bugs and\nothers which require adjustment of architecture code.\n\nFor this reason profiling the entire kernel is initially restricted\nto those architectures for which it is known to work without changes.\nThis restriction can be lifted once an architecture has been tested\nand found compatible with gcc\u0027s profiling. Profiling of single files\nor directories is still available on all platforms (see config help\ntext).\n\n[1] http://gcc.gnu.org/onlinedocs/gcc/Gcov.html\n\nSigned-off-by: Peter Oberparleiter \u003coberpar@linux.vnet.ibm.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Huang Ying \u003cying.huang@intel.com\u003e\nCc: Li Wei \u003cW.Li@Sun.COM\u003e\nCc: Michael Ellerman \u003cmichaele@au1.ibm.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Heiko Carstens \u003cheicars2@linux.vnet.ibm.com\u003e\nCc: Martin Schwidefsky \u003cmschwid2@linux.vnet.ibm.com\u003e\nCc: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nCc: WANG Cong \u003cxiyou.wangcong@gmail.com\u003e\nCc: Sam Ravnborg \u003csam@ravnborg.org\u003e\nCc: Jeff Dike \u003cjdike@addtoit.com\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
