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": "30c96ce56a195963764de9521087202ba73e9bff", "tree": "d2efc82338c0efea307cf9cb5a1cf10f218d4e26", "parents": [ "3e21ec224f0acbd2e9beeb3dea04edc1d36dbe1f" ], "author": { "name": "Jani Nikula", "email": "ext-jani.1.nikula@nokia.com", "time": "Thu Mar 11 18:15:53 2010 +0200" }, "committer": { "name": "Jiri Kosina", "email": "jkosina@suse.cz", "time": "Mon Mar 15 15:31:04 2010 +0100" }, "message": "powerpc/BSR: fix device_create() return value check\n\nUse IS_ERR() instead of comparing to NULL.\n\nSigned-off-by: Jani Nikula \u003cext-jani.1.nikula@nokia.com\u003e\nAcked-by: Sonny Rao \u003csonnyrao@us.ibm.com\u003e\nSigned-off-by: Jiri Kosina \u003cjkosina@suse.cz\u003e\n" }, { "commit": "04a85d1234d7e1682a612565e663e6b760918643", "tree": "62acf7f52104c71748e6d2884d0389c146b6e6bf", "parents": [ "e4031d52c57b17c76bbdb15fcf1a32a9f87d9756" ], "author": { "name": "Sonny Rao", "email": "sonnyrao@us.ibm.com", "time": "Thu Jun 18 15:13:04 2009 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri Jun 26 14:37:26 2009 +1000" }, "message": "powerpc/BSR: Fix BSR to allow mmap of small BSR on 64k kernel\n\nOn Mon, Nov 17, 2008 at 01:26:13AM -0600, Sonny Rao wrote:\n\u003e On Fri, Nov 07, 2008 at 04:28:29PM +1100, Paul Mackerras wrote:\n\u003e \u003e Sonny Rao writes:\n\u003e \u003e\n\u003e \u003e \u003e Fix the BSR driver to allow small BSR devices, which are limited to a\n\u003e \u003e \u003e single 4k space, on a 64k page kernel.

So, it\u0027s not possible to determine if\n\u003e the user wants one 4k page or more. As I noted in my first response,\n\u003e there is only one case where this is even possible and I don\u0027t think\n\u003e it is a significant concern.\n\u003e\n\u003e I did notice that I left out the check to see if the user is trying to\n\u003e map more than the device length, so I fixed that. Here\u0027s the revised\n\u003e patch.\n\nAlright, I\u0027ve reworked this now so that if we get one of these cases\nwhere there\u0027s a bsr that\u0027s \u003e 4k and \u003c 64k on a 64k kernel we\u0027ll only\nadvertise that it is a 4k BSR to userspace. I think this is the best\nsolution since user programs are only supposed to look at sysfs to\ndetermine how much can be mapped, and libbsr does this as well.\n\nPlease consider for 2.6.31 as a fix, thanks.\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "e4031d52c57b17c76bbdb15fcf1a32a9f87d9756", "tree": "ec50f6143d2ca15cdd4e4a4bdb8ca9ee311450b7", "parents": [ "4a5cbf17c49a6024a6d7baf03efdffb8ed252bb1" ], "author": { "name": "Sonny Rao", "email": "sonnyrao@us.ibm.com", "time": "Thu Jun 18 15:14:36 2009 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri Jun 26 14:37:26 2009 +1000" }, "message": "powerpc/BSR: add 4096 byte BSR size\n\nAdd a 4096 byte BSR size which will be used on new machines.
