This is done via\ngenerating inline assembly using C preprocessing which forces the\nassembler to generate external reference. This happens behind the\ncompiler\u0027s back and makes the compiler think that static percpu variables\nin modules are unused.\n\nThis used to be worked around by using __unused attribute for percpu\nvariables which prevent the compiler from omitting the variable; however,\nrecent declare/definition attribute unification change broke this as\n__used can\u0027t be used for declaration. Also, in the process,\nPER_CPU_ATTRIBUTES definition in alpha percpu.h got broken.\n\nThis patch adds PER_CPU_DEF_ATTRIBUTES which is only used for definitions\nand make alpha use it to add __used for percpu variables in modules. This\nalso fixes the PER_CPU_ATTRIBUTES double definition bug.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nTested-by: maximilian attems \u003cmax@stro.at\u003e\nAcked-by: Ivan Kokshaysky \u003cink@jurassic.park.msu.ru\u003e\nCc: Richard Henderson \u003crth@twiddle.net\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "5028eaa97dd1dab9cd7c30c4d38f71c708ca64bc", "tree": "ff416e9ecb00ab2b616bce6acc4e2579c45b06b9", "parents": [ "9b8de7479d0dbab1ed98b5b015d44232c9d3d08e" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Tue Apr 21 23:00:29 2009 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Apr 21 19:40:00 2009 -0700" }, "message": "PERCPU: Collect the DECLARE/DEFINE declarations together\n\nCollect the DECLARE/DEFINE declarations together in linux/percpu-defs.h so\nthat they\u0027re in one place, and give them descriptive comments, particularly\nthe SHARED_ALIGNED variant.\n\nIt would be nice to collect these in linux/percpu.h, but that\u0027s not possible\nwithout sorting out the severe #include recursion between the x86 arch headers\nand the general headers (and possibly other arches too).\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" } ] }
