But the glibc version is\nquite fast, in some cases it is 10 times faster than the kernel version. So I\nintroduce some memory copy macros and functions of the glibc to improve the\nkernel version's performance.\n\nThe strategy of the memory functions is:\n1. Copy bytes until the destination pointer is aligned.\n2. Copy words in unrolled loops.  If the source and destination are not\n   aligned in the same way, use word memory operations, but shift and merge\n   two read words before writing.\n3. Copy the few remaining bytes.\n\nSigned-off-by: Miao Xie <miaox*******>\n\nConflicts:\n\n\tlib/Makefile\nSigned-off-by: flar2 <asegaert@gmail.com>\n\nConflicts:\n\tlib/Makefile","distinct":true,"url":"https://api.github.com/repos/TGM-Hybrid/green_machine_bacon/commits/5a3c48a6b53587c157482b2e457ebca5e5433dda"},{"sha":"8769b12d601da1bf068befdb6459169f7d1deb9e","author":{"email":"d7ca2ed3e31360a26e5e60317ed1b792bd41becb@hp.com","name":"Davidlohr Bueso"},"message":"lib/int_sqrt.c: optimize square root algorithm\n\nOptimize the current version of the shift-and-subtract (hardware)\nalgorithm, described by John von Newmann[1] and Guy L Steele.\n\nIterating 1,000,000 times, perf shows for the current version:\n\n Performance counter stats for './sqrt-curr' (10 runs):\n\n         27.170996 task-clock                #    0.979 CPUs utilized            ( +-  3.19% )\n                 3 context-switches          #    0.103 K/sec                    ( +-  4.76% )\n                 0 cpu-migrations            #    0.004 K/sec                    ( +-100.00% )\n               104 page-faults               #    0.004 M/sec                    ( +-  0.16% )\n        64,921,199 cycles                    #    2.389 GHz                      ( +-  0.03% )\n        28,967,789 stalled-cycles-frontend   #   44.62% frontend cycles idle     ( +-  0.18% )\n   <not supported> stalled-cycles-backend\n       104,502,623 instructions              #    1.61  insns per cycle\n                                             #    0.28  stalled cycles per insn  ( +-  0.00% )\n        34,088,368 branches                  # 1254.587 M/sec                    ( +-  0.00% )\n             4,901 branch-misses             #    0.01% of all branches          ( +-  1.32% )\n\n       0.027763015 seconds time elapsed                                          ( +-  3.22% )\n\nAnd for the new version:\n\nPerformance counter stats for './sqrt-new' (10 runs):\n\n          0.496869 task-clock                #    0.519 CPUs utilized            ( +-  2.38% )\n                 0 context-switches          #    0.000 K/sec\n                 0 cpu-migrations            #    0.403 K/sec                    ( +-100.00% )\n               104 page-faults               #    0.209 M/sec                    ( +-  0.15% )\n           590,760 cycles                    #    1.189 GHz                      ( +-  2.35% )\n           395,053 stalled-cycles-frontend   #   66.87% frontend cycles idle     ( +-  3.67% )\n   <not supported> stalled-cycles-backend\n           398,963 instructions              #    0.68  insns per cycle\n                                             #    0.99  stalled cycles per insn  ( +-  0.39% )\n            70,228 branches                  #  141.341 M/sec                    ( +-  0.36% )\n             3,364 branch-misses             #    4.79% of all branches          ( +-  5.45% )\n\n       0.000957440 seconds time elapsed                                          ( +-  2.42% )\n\nFurthermore, this saves space in instruction text:\n\n   text    data     bss     dec     hex filename\n    111       0       0     111      6f lib/int_sqrt-baseline.o\n     89       0       0      89      59 lib/int_sqrt.o\n\n[1] http://en.wikipedia.org/wiki/First_Draft_of_a_Report_on_the_EDVAC\n\nSigned-off-by: Davidlohr Bueso <davidlohr.bueso@hp.com>\nReviewed-by: Jonathan Gonzalez <jgonzlez@linets.cl>\nTested-by: Jonathan Gonzalez <jgonzlez@linets.cl>\nSigned-off-by: Andrew Morton <akpm@linux-foundation.org>\nSigned-off-by: Linus Torvalds <torvalds@linux-foundation.org>\nSigned-off-by: flar2 <asegaert@gmail.com>","distinct":true,"url":"https://api.github.com/repos/TGM-Hybrid/green_machine_bacon/commits/8769b12d601da1bf068befdb6459169f7d1deb9e"},{"sha":"2f1798a3e20632ec8821e67214deff9fc8c2b17d","author":{"email":"602733bbf830274d69620a4044352b6860a52d50@gmail.com","name":"DerRomtester"},"message":"power: msm_battery: increase battery check interval from 5 to 15 seconds\n\nSigned-off-by: DerRomtester <dieb.stefan.96@gmail.com>","distinct":true,"url":"https://api.github.com/repos/TGM-Hybrid/green_machine_bacon/commits/2f1798a3e20632ec8821e67214deff9fc8c2b17d"},{"sha":"272fc152b29c585eaf3738eeea988a1478f3ff81","author":{"email":"2926236e622576bb8c477b2124dcaa6daa55bbd7@gmail.com","name":"YoshiShaPow"},"message":"sched: toggle features\n\ndisable gentle fair sleeprs\n\nenable arch power\n\nSigned-off-by: YoshiShaPow <yoshipga@gmail.com>","distinct":true,"url":"https://api.github.com/repos/TGM-Hybrid/green_machine_bacon/commits/272fc152b29c585eaf3738eeea988a1478f3ff81"}]}
