It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "55436c91652b45be576b91ec96a8d65f6b7447fa", "tree": "e7f68501219105d8c303b6c069828c2ebea76729", "parents": [ "fa1ac57a317f927b8fb901e6270fc41fdaae8e1c" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Wed Mar 10 15:22:55 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 12 15:52:39 2010 -0800" }, "message": "mips: use generic ptrace_resume code\n\nUse the generic ptrace_resume code for PTRACE_SYSCALL, PTRACE_CONT and\nPTRACE_KILL.\n\nAlso the TIF_SYSCALL_TRACE thread flag is now cleared on PTRACE_KILL which\nit previously wasn\u0027t which is consistent with all architectures using the\nmodern ptrace code.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nAcked-by: Ralf Baechle \u003cralf@linux-mips.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "5cacdb4add1b1e50fe75edc50ebbb7bddd9cf5e7", "tree": "bd6595bb8c5c7e20ad01ed7ef766d873e5d26db3", "parents": [ "e28cbf22933d0c0ccaf3c4c27a1a263b41f73859" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Wed Mar 10 15:21:21 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 12 15:52:32 2010 -0800" }, "message": "Add generic sys_olduname()\n\nAdd generic implementations of the old and really old uname system calls.\nNote that sh only implements sys_olduname but not sys_oldolduname, but I\u0027m\nnot going to bother with another ifdef for that special case.\n\nm32r implemented an old uname but never wired it up, so kill it, too.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: Paul Mundt \u003clethal@linux-sh.org\u003e\nCc: Jeff Dike \u003cjdike@addtoit.com\u003e\nCc: Hirokazu Takata \u003ctakata@linux-m32r.org\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: H.

first, try to enable the option -mmcount-ra-address in\narch/mips/Makefile with cc-option, if gcc support it, it will be\nenabled, otherwise, no side effect.\n\nand then, we need to support this new option of gcc 4.5 and also support\nthe old gcc versions.\n\nwith _mcount in the old gcc versions, it\u0027s not easy to get the location\nof return address(tracing: add function graph tracer support for MIPS),\n so, we do it in a C function: ftrace_get_parent_addr(ftrace.c), but\n with -mmcount-ra-address, only several instructions need to get what\n we want, so, I put into asm(mcount.S). and also, as the $12(t0) is\n used by -mmcount-ra-address for transferring the localtion of return\n address to _mcount, we need to save it into the stack and restore it\n when enabled dynamic function

Tracing: Add dynamic function tracer support\n\nWith dynamic function tracer, by default, _mcount is defined as an\n\"empty\" function, it returns directly without any more action . When\nenabling it in user-space, it will jump to a real tracing\nfunction(ftrace_caller), and do the real job for us.\n\nDiffer from the static function tracer, dynamic function tracer provides\ntwo functions ftrace_make_call()/ftrace_make_nop() to enable/disable the\ntracing of some indicated kernel functions(set_ftrace_filter).\n\nIn the -v4 version, the implementation of this support is basically the same as\nX86 version does: _mcount is implemented as an empty function and ftrace_caller\nis implemented as a real tracing function respectively.\n\nBut in this version, to support module tracing with the help of\n-mlong-calls in arch/mips/Makefile:\n\nMODFLAGS +\u003d -mlong-calls.\n\nThe stuff becomes a little more complex. We need to cope with two\ndifferent type of calling to _mcount.\n\nFor the kernel part, the calling to _mcount(result of \"objdump -hdr\nvmlinux\"). is like this:\n\n\t108: 03e0082d move at,ra\n\t10c: 0c000000 jal 0 \u003cfpcsr_pending\u003e\n 10c: R_MIPS_26 _mcount\n 10c: R_MIPS_NONE *ABS*\n 10c: R_MIPS_NONE *ABS*\n\t110: 00020021 nop\n\nFor the module with -mlong-calls, it looks like this:\n\n\tc:\t3c030000 \tlui\tv1,0x0\n\t\t\tc: R_MIPS_HI16\t_mcount\n\t\t\tc: R_MIPS_NONE\t*ABS*\n\t\t\tc: R_MIPS_NONE\t*ABS*\n\t10:\t64630000 \tdaddiu\tv1,v1,0\n\t\t\t10: R_MIPS_LO16\t_mcount\n\t\t\t10: R_MIPS_NONE\t*ABS*\n\t\t\t10: R_MIPS_NONE\t*ABS*\n\t14:\t03e0082d \tmove\tat,ra\n\t18:\t0060f809 \tjalr\tv1\n\nIn the kernel version, there is only one \"_mcount\" string for every\nkernel function, so, we just need to match this one in mcount_regex of\nscripts/recordmcount.pl, but in the module version, we need to choose\none of the two to match. Herein, I choose the first one with\n\"R_MIPS_HI16 _mcount\".\n\nand In the kernel verion, without module tracing support, we just need\nto replace \"jal _mcount\" by \"jal ftrace_caller\" to do real tracing, and\nfilter the tracing of some kernel functions via replacing it by a nop\ninstruction.\n\nbut as we have described before, the instruction \"jal ftrace_caller\" only left\n32bit length for the address of ftrace_caller, it will fail when calling from\nthe module space. so, herein, we must replace something else.\n\nthe basic idea is loading the address of ftrace_caller to v1 via changing these\ntwo instructions:\n\n\tlui\tv1,0x0\n\taddiu\tv1,v1,0\n\nIf we want to enable the tracing, we need to replace the above instructions to:\n\n\tlui\tv1, HI_16BIT_ftrace_caller\n\taddiu\tv1, v1, LOW_16BIT_ftrace_caller\n\nIf we want to stop the tracing of the indicated kernel functions, we\njust need to replace the \"jalr v1\" to a nop instruction. but we need to\nreplace two instructions and encode the above two instructions\noursevles.\n\nIs there a simpler solution? Yes! Here it is, in this version, we put _mcount\nand ftrace_caller together, which means the address of _mcount and\nftrace_caller is the same:\n\n_mcount:\nftrace_caller:\n\tj\tftrace_stub\n\t nop\n\n\t...(do real tracing here)...\n\nftrace_stub:\n\tjr\tra\n\t move\tra, at\n\nBy default, the kernel functions call _mcount, and then jump to ftrace_stub and\nreturn. and when we want to do real tracing, we just need to remove that \"j\nftrace_stub\", and it will run through the two \"nop\" instructions and then do\nthe real tracing job.\n\nwhat about filtering job? we just need to do this:\n\n\t lui v1, hi_16bit_of_mcount \u003c--\u003e b 1f (0x10000004)\n\t addiu v1, v1, low_16bit_of_mcount\n\t move at, ra\n\t jalr v1\n\t nop\n\t \t\t\t\t 1f: (rec-\u003eip + 12)\n\nIn linux-mips64, there will be some local symbols, whose name are\nprefixed by $L, which need to be filtered. thanks goes to Steven for\nwriting the mips64-specific function_regex.\n\nIn a conclusion, with RISC, things becomes easier with such a \"stupid\"\ntrick, RISC is something like K.I.S.S, and also, there are lots of\n\"simple\" tricks in the whole ftrace support, thanks goes to Steven and\nthe other folks for providing such a wonderful tracing framework!\n\nSigned-off-by: Wu Zhangjin \u003cwuzhangjin@gmail.com\u003e\nCc: Nicholas Mc Guire \u003cder.herr@hofr.at\u003e\nCc: zhangfx@lemote.com\nCc: Wu Zhangjin \u003cwuzhangjin@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: linux-kernel@vger.kernel.org\nCc: linux-mips@linux-mips.org\nPatchwork: http://patchwork.linux-mips.org/patch/675/\nAcked-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nSigned-off-by: Ralf Baechle \u003cralf@linux-mips.org\u003e\n" }, { "commit": "69a7d1b3ec64786cfc8a16ef3e8585d1f93d3944", "tree": "543a4a531bb1e573984e8f855cd530748d05306d", "parents": [ "d2bb0762993e11363d8343127516b8fe88f9006f" ], "author": { "name": "Wu Zhangjin", "email": "wuzhangjin@gmail.com", "time": "Fri Nov 20 20:34:30 2009 +0800" }, "committer": { "name": "Ralf Baechle", "email": "ralf@linux-mips.org", "time": "Thu Dec 17 01:57:22 2009 +0000" }, "message": "MIPS: Tracing: Enable HAVE_FUNCTION_TRACE_MCOUNT_TEST for MIPS\n\nThere is an exisiting common ftrace_test_stop_func() in\nkernel/trace/ftrace.c, which is used to check the global variable\nftrace_trace_stop to determine whether stop the function tracing.\n\nThis patch implepment the MIPS specific one to speedup the procedure.\n\nThanks goes to Zhang Le for Cleaning it up.\n\nSigned-off-by: Wu Zhangjin \u003cwuzhangjin@gmail.com\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Nicholas Mc Guire \u003cder.herr@hofr.at\u003e\nCc: zhangfx@lemote.com\nCc: Wu Zhangjin \u003cwuzhangjin@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: linux-kernel@vger.kernel.org\nCc: linux-mips@linux-mips.org\nPatchwork: http://patchwork.linux-mips.org/patch/673/\nSigned-off-by: Ralf Baechle \u003cralf@linux-mips.org\u003e\n" }, { "commit": "d2bb0762993e11363d8343127516b8fe88f9006f", "tree": "f210c4c4b0234a776977e6d2b749384e1d3699c1", "parents": [ "8922f79ee56e9dab6fc144defc0bc901ff0a7f8a" ], "author": { "name": "Wu Zhangjin", "email": "wuzhangjin@gmail.com", "time": "Fri Nov 20 20:34:29 2009 +0800" }, "committer": { "name": "Ralf Baechle", "email": "ralf@linux-mips.org", "time": "Thu Dec 17 01:57:21 2009 +0000" }, "message": "MIPS: Tracing: Add static function tracer support for MIPS\n\nIf -pg of gcc is enabled with CONFIG_FUNCTION_TRACER\u003dy. a calling to\n_mcount will be inserted into each kernel function. so, there is a\npossibility to trace the kernel functions in _mcount.\n\nThis patch add the MIPS specific _mcount support for static function\ntracing. by default, ftrace_trace_function is initialized as\nftrace_stub(an empty function), so, the default _mcount will introduce\nvery little overhead. after enabling ftrace in user-space, it will jump\nto a real tracing function and do static function tracing for us.\n\nand -ffunction-sections is incompatible with -pg, so, disable it when\nftracer is enabled.\n\nSigned-off-by: Wu Zhangjin \u003cwuzhangjin@gmail.com\u003e\nReviewed-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Nicholas Mc Guire \u003cder.herr@hofr.at\u003e\nCc: zhangfx@lemote.com\nCc: Wu Zhangjin \u003cwuzhangjin@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: linux-kernel@vger.kernel.org\nCc: linux-mips@linux-mips.org\nPatchwork: http://patchwork.linux-mips.org/patch/672/\nSigned-off-by: Ralf Baechle \u003cralf@linux-mips.org\u003e\n" }, { "commit": "f8ede0f700f5478851f242f291d203cde54ca6cf", "tree": "37fba17288bcd12468c454eb6c585d72fb6f9770", "parents": [ "9726b43a4d7aaa5b30f559e78768aeb3d17bc224" ], "author": { "name": "Wu Zhangjin", "email": "wuzhangjin@gmail.com", "time": "Tue Nov 17 01:32:59 2009 +0800" }, "committer": { "name": "Ralf Baechle", "email": "ralf@linux-mips.org", "time": "Thu Dec 17 01:57:20 2009 +0000" }, "message": "MIPS: Loongson 2F: Add CPU frequency scaling support\n\nLoongson 2F supports CPU clock scaling.

This patch intends to actually give us real O_SYNC\nsemantics in addition to the O_DSYNC semantics. After Jan\u0027s O_SYNC\npatches which are required before this patch it\u0027s actually surprisingly\nsimple, we just need to figure out when to set the datasync flag to\nvfs_fsync_range and when not.\n\nThis patch renames the existing O_SYNC flag to O_DSYNC while keeping it\u0027s\nnumerical value to keep binary compatibility, and adds a new real O_SYNC\nflag. To guarantee backwards compatiblity it is defined as expanding to\nboth the O_DSYNC and the new additional binary flag (__O_SYNC) to make\nsure we are backwards-compatible when compiled against the new headers.\n\nThis also means that all places that don\u0027t care about the differences can\njust check O_DSYNC and get the right behaviour for O_SYNC, too - only\nplaces that actuall care need to check __O_SYNC in addition. Drivers and\nnetwork filesystems have been updated in a fail safe way to always do the\nfull sync magic if O_DSYNC is set. The few places setting O_SYNC for\nlower layers are kept that way for now to stay failsafe.\n\nWe enforce that O_DSYNC is set when __O_SYNC is set early in the open path\nto make sure we always get these sane options.\n\nNote that parisc really screwed up their headers as they already define a\nO_DSYNC that has always been a no-op. We try to repair it by using it for\nthe new O_DSYNC and redefinining O_SYNC to send both the traditional\nO_SYNC numerical value _and_ the O_DSYNC one.\n\nCc: Richard Henderson \u003crth@twiddle.net\u003e\nCc: Ivan Kokshaysky \u003cink@jurassic.park.msu.ru\u003e\nCc: Grant Grundler \u003cgrundler@parisc-linux.org\u003e\nCc: \"David S.
