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": "d7b4627f5f3390a2f350f16c047b3fc3eccce6d8", "tree": "a16cb396fca7f3bec6f9f3188fa535cb71007bc8", "parents": [ "5aa3a333eaae1016f5a72f9e0e2dce39c08762f8" ], "author": { "name": "Wayne Boyer", "email": "wayneb@linux.vnet.ibm.com", "time": "Fri Feb 19 13:24:38 2010 -0800" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Wed Mar 03 16:05:05 2010 +0530" }, "message": "[SCSI] ipr: adds PCI ID definitions for new adapters\n\nThis patch adds the PCI ID definitions for new adapters based on the next\ngeneration 64 bit IOA PCI interface chip.

These changes introduced a regression on ipr EEH\nrecovery.\n\nThe ipr device driver saves the PCI state only during the device probe\nand restores it on ipr_reset_restore_cfg_space() during IOA resets. This\nbehavior is causing the EEH recovery to fail after the second error\ndetected, since the registers are not being restored.\n\nOne possible solution would be saving the registers after restoring\nthem. The problem with this approach is that while recovering from an\nEEH error if pci_save_state() results in an EEH error, the adapter/slot\nwill be reset, and end up back in ipr_reset_restore_cfg_space(), but it\nwon\u0027t have a valid saved state to restore, so pci_restore_state() will\nfail.\n\nThe following patch introduces a workaround for this problem, hacking\naround the PCI API by setting pdev-\u003estate_saved \u003d true before we do the\nrestore. It fixes the EEH regression and prevents that we hit another\nEEH error during EEH recovery.\n\n\n[jejb: fix is a hack ...

It\u0027s done this way for two reasons.\n\nFirst, the ops table already contained too many methods and adding\nfour more of them would noticeably increase the amount of necessary\nboilerplate code all over low level drivers.\n\nSecond, as -\u003eerror_handler uses those reset methods, it can get\nconfusing. ie.

The second isn\u0027t completely solved but is relieved by\nproviding default values - most drivers can just override what it has\nimplemented and don\u0027t have to concern itself about higher level\ncallbacks. In fact, there currently is no driver which actually\nmodifies error handling behavior.

However, as of 2.5, the block layer has a\ndma_alignment variable which ensures both the beginning and length of a\nDMA transfer are aligned on the dma_alignment boundary. Although the\nblock layer does adjust the beginning of the transfer to ensure this\nhappens, it doesn\u0027t actually adjust the length, it merely makes sure\nthat space is allocated for transfers beyond the declared length. The\nupshot of this is that scatterlists may be padded to any size between\nthe actual length and the length adjusted to the dma_alignment safely\nknowing that memory is allocated in this region.\n\nRight at the moment, SCSI takes the default dma_aligment which is on a\n512 byte boundary. Note that this aligment only applies to transfers\ncoming in from user space. However, since all kernel allocations are\nautomatically aligned on a minimum of 32 byte boundaries, it is safe to\nadjust them in this manner as well.\n\ntj: * Adjusting sg after padding is done in block layer.
