"arch/ia64/Makefile: Remove -mtune\u003dmerced in IA64 kernel build\n\nBetween GCC version 3.4.0 and 4.3.3 (including 3.4.0 and 4.3.3), -mtune\u003dmerced\nis implemented in GCC. Starting from 4.4.0, -mtune\u003dmerced is deprecated.\n\nEven implemented in versions between 3.4.0 and 4.3.3, the -mtune\u003dmerced\nfeature has been broken in some of the versions. For example, GCC 4.1.2 reports\ninteranl tuning function errors during kernel building with -mtune\u003dmerced. Or\nGCC Bugzilla 16130 reports another -mtune\u003dmerced issue on GCC 3.4.1.\n\nSo I would remove the -mtune\u003dmerced from IA64 kernel build. Without this option,\nkernel on Merced will remain the same except losing an unstable and out-of-date\nperformance tunning feature.\n\nSince GCC version 3.4.0, -mtune\u003dmckinley has been implemented. The\n-mtune\u003dmckinley option functions the same as mtune\u003ditanium2. And mtune\u003ditanium2\nis the default option. So we don\u0027t need to add mtune\u003dmckinley either since its\nbeen the default option in any GCC version which implements this option.\n\nSigned-off-by: Fenghua Yu \u003cfenghua.yu@intel.com\u003e\n" }, { "commit": "b5a8879347bbe68bd24c8870503bf6a0362da26b", "tree": "fb89816655d8a92e6701724943760fca3d3dde41", "parents": [ "cfa5f809e399c699974ba6018eefa022bbc2e16e" ], "author": { "name": "Jaswinder Singh Rajput", "email": "[jaswinder@kernel.org]", "time": "Tue Aug 11 14:52:11 2009 -0700" }, "committer": { "name": "Fenghua Yu", "email": "fenghua.yu@intel.com", "time": "Tue Aug 11 14:52:11 2009 -0700" }, "message": "IA64: includecheck fix: ia64, pgtable.h\n\nfix the following \u0027make includecheck\u0027 warning:\n\n arch/ia64/include/asm/pgtable.h: asm/processor.h is included more than once.\n\nSigned-off-by: Jaswinder Singh Rajput \u003cjaswinderrajput@gmail.com\u003e\nAcked-by: Fenghua Yu \u003cfenghua.yu@intel.com\u003e\n" }, { "commit": "cfa5f809e399c699974ba6018eefa022bbc2e16e", "tree": "1667615979c8ca634f528c1e43566020874a1feb", "parents": [ "8d6f9af91959256244878cd801c1c969e66cd093" ], "author": { "name": "Jaswinder Singh Rajput", "email": "[jaswinder@kernel.org]", "time": "Tue Aug 11 14:52:10 2009 -0700" }, "committer": { "name": "Fenghua Yu", "email": "fenghua.yu@intel.com", "time": "Tue Aug 11 14:52:10 2009 -0700" }, "message": "IA64: includecheck fix: ia64, ia64_ksyms.c\n\nfix the following \u0027make includecheck\u0027 warning:\n\n arch/ia64/kernel/ia64_ksyms.c: asm/page.h is included more than once.\n\nSigned-off-by: Jaswinder Singh Rajput \u003cjaswinderrajput@gmail.com\u003e\nAcked-by: Fenghua Yu \u003cfenghua.yu@intel.com\u003e\n" }, { "commit": "8d6f9af91959256244878cd801c1c969e66cd093", "tree": "bd1dde34d4a3ef472d0a35d05b11320f762fd51f", "parents": [ "51b89f7a6615eca184aa0b85db5781d931e9c8d1" ], "author": { "name": "Johannes Weiner", "email": "[hannes@cmpxchg.org]", "time": "Tue Aug 11 14:52:10 2009 -0700" }, "committer": { "name": "Fenghua Yu", "email": "fenghua.yu@intel.com", "time": "Tue Aug 11 14:52:10 2009 -0700" }, "message": "ia64: boolean __test_and_clear_bit\n\n__test_and_clear_bit() returns a bitfield with the tested-for bit set.\nMake it consistent with the other bitops - of ia64 but also every\nother architecture - and return a boolean value.\n\nSigned-off-by: Johannes Weiner \u003channes@cmpxchg.org\u003e\nAcked-by: Fenghua Yu \u003cfenghua.yu@intel.com\u003e\n" }, { "commit": "51b89f7a6615eca184aa0b85db5781d931e9c8d1", "tree": "29b8afd81fc022d01eb81ea26a663aefaaacdc2f", "parents": [ "85dfd81dc57e8183a277ddd7a56aa65c96f3f487" ], "author": { "name": "Fenghua Yu", "email": "[fenghua.yu@intel.com]", "time": "Tue Aug 11 14:52:10 2009 -0700" }, "committer": { "name": "Fenghua Yu", "email": "fenghua.yu@intel.com", "time": "Tue Aug 11 14:52:10 2009 -0700" }, "message": "Bug Fix arch/ia64/kernel/pci-dma.c: fix recursive dma_supported() call in iommu_dma_supported()\n\nIn commit 160c1d8e40866edfeae7d68816b7005d70acf391,\ndma_ops-\u003edma_supported \u003d iommu_dma_supported;\n\nThis dma_ops-\u003edma_supported is first called in platform_dma_init() during kernel\nboot.
