This is set up in arch_prepare_hugepage(),\nwhich is called from alloc_fresh_huge_page_node().\n\nA similar call to arch_prepare_hugepage() is missing for surplus large\npages that are allocated in alloc_buddy_huge_page(), which breaks the\nsoftware emulation mode for (surplus) large pages on s390. This patch\nadds the missing call to arch_prepare_hugepage(). It will have no effect\non other architectures where arch_prepare_hugepage() is a nop.\n\nAlso, use the correct order in the error path in alloc_fresh_huge_page_node().\n\nAcked-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nSigned-off-by: Gerald Schaefer \u003cgerald.schaefer@de.ibm.com\u003e\nAcked-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nAcked-by: Adam Litke \u003cagl@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "02eb7eeb8990b9cbd32c7bc1ef2d431ca390e44a", "tree": "ed35226d481e861446c722b545e28410e740e04c", "parents": [ "45fc3c4d9b7ab12798af43a73aea53eeecd16acf" ], "author": { "name": "Adrian Bunk", "email": "bunk@kernel.org", "time": "Tue Aug 12 15:08:37 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Aug 12 16:07:27 2008 -0700" }, "message": "feature-removal-schedule.txt: remove the NCR53C9x entry\n\nNow that the driver is removed we should also remove the entry in\nDocumentation/feature-removal-schedule.txt\n\nSigned-off-by: Adrian Bunk \u003cbunk@kernel.org\u003e\nAcked-by: Christoph Hellwig \u003chch@lst.de\u003e\nCc: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "45fc3c4d9b7ab12798af43a73aea53eeecd16acf", "tree": "70281ada76ebc49572505baea6e442b265ceb5e4", "parents": [ "96348852cf8ff5597a39e866838679b3a9a38947", "9e6dd47bf365f8f7bccea10f22fbbdbecce429e8" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Aug 12 09:14:24 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Aug 12 09:14:24 2008 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6:\n ALSA: hda -

You can obviously screw up and take the same lock _twice_\n\u003e (which will deadlock), but at least you cannot get into ABBA situations.\n\u003e\n\u003e So maybe the right thing to do is to just teach lockdep about \"lock\n\u003e protection locks\". That would have solved the multi-queue issues for\n\u003e networking too - all the actual network drivers would still have taken\n\u003e just their single queue lock, but the one case that needs to take all of\n\u003e them would have taken a separate top-level lock first.\n\u003e\n\u003e Never mind that the multi-queue locks were always taken in the same order:\n\u003e it\u0027s never wrong to just have some top-level serialization, and anybody\n\u003e who needs to take \u003cn\u003e locks might as well do \u003cn+1\u003e, because they sure as\n\u003e hell aren\u0027t going to be on _any_ fastpaths.\n\u003e\n\u003e So the simplest solution really sounds like just teaching lockdep about\n\u003e that one special case. It\u0027s not \"nesting\" exactly, although it\u0027s obviously\n\u003e related to it.\n\nDo as Linus suggested.
