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": "bca3469205402d9fb14060d255d8786ae2256640", "tree": "3b0c7f246fb9a6eafd3a82dd621dd9753589b3f4", "parents": [ "0793448187643b50af89d36b08470baf45a3cab4" ], "author": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Fri Mar 26 16:52:10 2010 -0700" }, "committer": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Fri Mar 26 16:52:10 2010 -0700" }, "message": "dmaengine: provide helper for setting txstate\n\nSimple conditional struct filler to cut out some duplicated code.\n\nSigned-off-by: Dan Williams \u003cdan.j.williams@intel.com\u003e\n" }, { "commit": "0793448187643b50af89d36b08470baf45a3cab4", "tree": "b3313ff58d47e26a8cf707d196177effa1aadfbe", "parents": [ "c3635c78e500a52c9fcd55de381a72928d9e054d" ], "author": { "name": "Linus Walleij", "email": "linus.walleij@stericsson.com", "time": "Fri Mar 26 16:50:49 2010 -0700" }, "committer": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Fri Mar 26 16:50:49 2010 -0700" }, "message": "DMAENGINE: generic channel status v2\n\nConvert the device_is_tx_complete() operation on the\nDMA engine to a generic device_tx_status()operation which\ncan return three states, DMA_TX_RUNNING, DMA_TX_COMPLETE,\nDMA_TX_PAUSED.\n\n[dan.j.williams@intel.com: update for timberdale]\nSigned-off-by: Linus Walleij \u003clinus.walleij@stericsson.com\u003e\nAcked-by: Mark Brown \u003cbroonie@opensource.wolfsonmicro.com\u003e\nCc: Maciej Sosnowski \u003cmaciej.sosnowski@intel.com\u003e\nCc: Nicolas Ferre \u003cnicolas.ferre@atmel.com\u003e\nCc: Pavel Machek \u003cpavel@ucw.cz\u003e\nCc: Li Yang \u003cleoli@freescale.com\u003e\nCc: Guennadi Liakhovetski \u003cg.liakhovetski@gmx.de\u003e\nCc: Paul Mundt \u003clethal@linux-sh.org\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCc: Haavard Skinnemoen \u003chaavard.skinnemoen@atmel.com\u003e\nCc: Magnus Damm \u003cdamm@opensource.se\u003e\nCc: Liam Girdwood \u003clrg@slimlogic.co.uk\u003e\nCc: Joe Perches \u003cjoe@perches.com\u003e\nCc: Roland Dreier \u003crdreier@cisco.com\u003e\nSigned-off-by: Dan Williams \u003cdan.j.williams@intel.com\u003e\n" }, { "commit": "c3635c78e500a52c9fcd55de381a72928d9e054d", "tree": "87403f402227cd8b5572550e70facf81c9eaa0d9", "parents": [ "0f65169b1bf44220308e1ce1f6666ad03ddc27af" ], "author": { "name": "Linus Walleij", "email": "linus.walleij@stericsson.com", "time": "Fri Mar 26 16:44:01 2010 -0700" }, "committer": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Fri Mar 26 16:44:01 2010 -0700" }, "message": "DMAENGINE: generic slave control v2\n\nConvert the device_terminate_all() operation on the\nDMA engine to a generic device_control() operation\nwhich can now optionally support also pausing and\nresuming DMA on a certain channel.
