However, going up 1 level wouldn\u0027t give any more empty slot so\nit takes C and when the whole thing restarts nobody notices the high bit\nset beyond the top level.\n\nThis patch fixes the bug by changing the fail exit condition check to full\nid limit check.\n\nBased-on-patch-from: Eric Paris \u003ceparis@redhat.com\u003e\nReported-by: Eric Paris \u003ceparis@redhat.com\u003e\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\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": "a02b11937a6e1079fdf386833129cd86a3576196", "tree": "52be329d505921205c8269baf50f83ff40b76b12", "parents": [ "d3ad9373b7c29b63d5e8460a69453718d200cc3b", "aeb583d08172e038552bdefe0a79a9aa9e2ecd7c" ], "author": { "name": "Joerg Roedel", "email": "joerg.roedel@amd.com", "time": "Fri Jan 22 18:00:41 2010 +0100" }, "committer": { "name": "Joerg Roedel", "email": "joerg.roedel@amd.com", "time": "Fri Jan 22 18:00:41 2010 +0100" }, "message": "Merge branches \u0027amd-iommu/fixes\u0027 and \u0027dma-debug/fixes\u0027 into iommu/fixes\n" }, { "commit": "aeb583d08172e038552bdefe0a79a9aa9e2ecd7c", "tree": "df348e4297162ecb83a98a517de1e3977a5d784c", "parents": [ "f797d9881b62c2ddb1d2e7bd80d87141949c84aa" ], "author": { "name": "Thiago Farina", "email": "tfransosi@gmail.com", "time": "Mon Jan 18 18:57:33 2010 -0500" }, "committer": { "name": "Joerg Roedel", "email": "joerg.roedel@amd.com", "time": "Fri Jan 22 17:59:51 2010 +0100" }, "message": "lib/dma-debug.c: mark file-local struct symbol static.\n\nwarning: symbol \u0027filter_fops\u0027 was not declared.

The only reason I\n: can think of ever using gzip would be if you needed the additional\n: compression (eg, because you have limited flash to store the image.)\n:\n: I would argue that the default for ARM should therefore be LZO.\n\nThis patch:\n\nThe lzo compressor is worse than gzip at compression, but faster at\nextraction. Here are some figures for an ARM board I\u0027m working on:\n\nUncompressed size: 3.24Mo\ngzip 1.61Mo 0.72s\nlzo 1.75Mo 0.48s\n\nSo for a compression ratio that is still relatively close to gzip, it\u0027s\nmuch faster to extract, at least in that case.\n\nThis part contains:\n - Makefile routine to support lzo compression\n - Fixes to the existing lzo compressor so that it can be used in\n compressed kernels\n - wrapper around the existing lzo1x_decompress, as it only extracts one\n block at a time, while we need to extract a whole file here\n - config dialog for kernel compression\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: cleanup]\nSigned-off-by: Albin Tonnerre \u003calbin.tonnerre@free-electrons.com\u003e\nTested-by: Wu Zhangjin \u003cwuzhangjin@gmail.com\u003e\nAcked-by: \"H.

patch (6698e3472: \"tty: Fix BKL taken under a\nspinlock bug introduced in the BKL split\") the BKL removal is prone to\nsome subtle issues, where removing the BKL in one place may in fact make\na previously nested BKL call the new outer call, and then prone to nasty\ndeadlocks with other spinlocks.\n\nIn general, we should never take the BKL while we\u0027re holding a spinlock,\nso let\u0027s just add a \"might_sleep()\" to it (even though the BKL doesn\u0027t\ntechnically sleep - at least not yet), and we\u0027ll get nice warnings the\nnext time this kind of problem happens during BKL

We need to allocate swiotlb memory\nearlier from bootmem allocator. Chris explained the issue in\ndetail:\n\n http://marc.info/?l\u003dlinux-kernel\u0026m\u003d125657444317079\u0026w\u003d2\n\nThe current x86 IOMMU initialization sequence is too complicated\nand handling the above issue makes it more hacky.\n\nThis patch changes x86 IOMMU initialization sequence to handle\nthe above issue cleanly.\n\nThe new x86 IOMMU initialization sequence are:\n\n1. we initialize the swiotlb (and setting swiotlb to 1) in the case\n of (max_pfn \u003e MAX_DMA32_PFN \u0026\u0026 !no_iommu). dma_ops is set to\n swiotlb_dma_ops or nommu_dma_ops. if swiotlb usage is forced by\n the boot option, we finish here.\n\n2. we call the detection functions of all the IOMMUs\n\n3. the detection function sets x86_init.iommu.iommu_init to the\n IOMMU initialization function (so we can avoid calling the\n initialization functions of all the IOMMUs needlessly).\n\n4. if the IOMMU initialization function doesn\u0027t need to swiotlb\n then sets swiotlb to zero (e.g. the initialization is\n sucessful).\n\n5. if we find that swiotlb is set to zero, we free swiotlb\n resource.\n\nSigned-off-by: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nCc: chrisw@sous-sol.org\nCc: dwmw2@infradead.org\nCc: joerg.roedel@amd.com\nCc: muli@il.ibm.com\nLKML-Reference: \u003c1257849980-22640-10-git-send-email-fujita.tomonori@lab.ntt.co.jp\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "ad32e8cb86e7894aac51c8963eaa9f36bb8a4e14", "tree": "4dce812e83de8bd130fd141afc1229b38b483736", "parents": [ "5740afdb68abadc473fd5392df733558a58c1254" ], "author": { "name": "FUJITA Tomonori", "email": "fujita.tomonori@lab.ntt.co.jp", "time": "Tue Nov 10 19:46:19 2009 +0900" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Nov 10 12:32:00 2009 +0100" }, "message": "swiotlb: Defer swiotlb init printing, export swiotlb_print_info()\n\nThis enables us to avoid printing swiotlb memory info when we\ninitialize swiotlb.
