The ultimate fix is in cpufreq\nto deal with incorrect values, but this patch improves the error\nrecovery in the AMD powernowk8 driver.\n\nThe failure that was reported was as follows:\n\npowernow-k8: Found 1 AMD Athlon(tm) 64 Processor 3700+ (1 cpu cores) (version 2.20.00)\npowernow-k8: fid 0x2 (1000 MHz), vid 0x12\npowernow-k8: fid 0xa (1800 MHz), vid 0xa\npowernow-k8: fid 0xc (2000 MHz), vid 0x8\npowernow-k8: fid 0xe (2200 MHz), vid 0x8\nMarking TSC unstable due to cpufreq changes\npowernow-k8: fid trans failed, fid 0x2, curr 0x0\nBUG: unable to handle kernel paging request at ffff880807e07b78\nIP: [\u003cffffffff81479163\u003e] cpufreq_stats_update+0x46/0x5b\n...\n\nAnd transition fails and data-\u003ecurrfid ends up with 0.

This patch fixes\nthe issue during target setting.\n\nThe patch however does not fix the issue in \u0027powernowk8_cpu_init\u0027\nwhere the pol-\u003ecur can also be set with the 800000 value:\n\n pol-\u003ecur \u003d find_khz_freq_from_fid(data-\u003ecurrfid);\n dprintk(\"policy current frequency %d kHz\\n\", pol-\u003ecur);\n\n /* min/max the cpu is capable of */\n if (cpufreq_frequency_table_cpuinfo(pol, data-\u003epowernow_table)) {\n\nThe fix for that looks to update cpufreq_frequency_table_cpuinfo to\ncheck pol-\u003ecur.... but that would cause an regression in how the\nacpi-cpufreq driver works (it sets cpu-\u003ecur after calling\ncpufreq_frequency_table_cpuinfo).

Currently, when we\nhotplug off only the first CPU, all of the symlinks and the sysfs\ndirectory gets removed. Even though rest of the siblings are still\nonline and functional, they are orphaned, and no longer governed by\ncpufreq.\n\nThis patch, given the above scenario, creates a sysfs directory for\nthe first sibling and symlinks for the rest of the siblings.\n\nPlease note the recursive call, it was rather too ugly to roll it\nout. And the removal of redundant NULL setting (it is already taken\ncare of near the top of the function).\n\nSigned-off-by: Jacob Shin \u003cjacob.shin@amd.com\u003e\nAcked-by: Mark Langsdorf \u003cmark.langsdorf@amd.com\u003e\nReviewed-by: Thomas Renninger \u003ctrenn@suse.de\u003e\nSigned-off-by: Dave Jones \u003cdavej@redhat.com\u003e\nCc: stable@kernel.org\n" }, { "commit": "25985edcedea6396277003854657b5f3cb31a628", "tree": "f026e810210a2ee7290caeb737c23cb6472b7c38", "parents": [ "6aba74f2791287ec407e0f92487a725a25908067" ], "author": { "name": "Lucas De Marchi", "email": "lucas.demarchi@profusion.mobi", "time": "Wed Mar 30 22:57:33 2011 -0300" }, "committer": { "name": "Lucas De Marchi", "email": "lucas.demarchi@profusion.mobi", "time": "Thu Mar 31 11:26:23 2011 -0300" }, "message": "Fix common misspellings\n\nFixes generated by \u0027codespell\u0027 and manually reviewed.\n\nSigned-off-by: Lucas De Marchi \u003clucas.demarchi@profusion.mobi\u003e\n" }, { "commit": "e00e56dfd3cf1d209ce630a2b440c91e4a30bbd3", "tree": "4d1329036e250db15411b21b15a158f9042945bd", "parents": [ "fb3600cc50302c9577b76838fcac1ee78828007d" ], "author": { "name": "Rafael J.

Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. 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": "52cf25d0ab7f78eeecc59ac652ed5090f69b619e", "tree": "031d1ffb3890bd69c0260c864c512e0be62ac05c", "parents": [ "6c1733aca0b48db4d0e660d54976a1cca25b5eaf" ], "author": { "name": "Emese Revfy", "email": "re.emese@gmail.com", "time": "Tue Jan 19 02:58:23 2010 +0100" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Sun Mar 07 17:04:49 2010 -0800" }, "message": "Driver core: Constify struct sysfs_ops in struct kobj_type\n\nConstify struct sysfs_ops.\n\nThis is part of the ops structure constification\neffort started by Arjan van de Ven et al.\n\nBenefits of this constification:\n\n * prevents modification of data that is shared\n (referenced) by many other structure instances\n at runtime\n\n * detects/prevents accidental (but not intentional)\n modification attempts on archs that enforce\n read-only kernel data at runtime\n\n * potentially better optimized code as the compiler\n can assume that the const data cannot be changed\n\n * the compiler/linker move const data into .rodata\n and therefore exclude them from false sharing\n\nSigned-off-by: Emese Revfy \u003cre.emese@gmail.com\u003e\nAcked-by: David Teigland \u003cteigland@redhat.com\u003e\nAcked-by: Matt Domsch \u003cMatt_Domsch@dell.com\u003e\nAcked-by: Maciej Sosnowski \u003cmaciej.sosnowski@intel.com\u003e\nAcked-by: Hans J.

Therefore, we need to ascertain\nas soon as possible that the CPU frequency is indeed at the speed we\nthink it is. You can do this two ways: either setting it anew, or trying\nto get it.
