It holds a number of\n low level bits with no/few dependencies that are commonly used (eg.\n memory barriers) and a number of bits with more dependencies that\n aren\u0027t used in many places (eg. switch_to()).\n\n These patches break asm/system.h up into the following core pieces:\n\n (1) asm/barrier.h\n\n Move memory barriers here. This already done for MIPS and Alpha.\n\n (2) asm/switch_to.h\n\n Move switch_to() and related stuff here.\n\n (3) asm/exec.h\n\n Move arch_align_stack() here. Other process execution related bits\n could perhaps go here from asm/processor.h.\n\n (4) asm/cmpxchg.h\n\n Move xchg() and cmpxchg() here as they\u0027re full word atomic ops and\n frequently used by atomic_xchg() and atomic_cmpxchg().\n\n (5) asm/bug.h\n\n Move die() and related bits.\n\n (6) asm/auxvec.h\n\n Move AT_VECTOR_SIZE_ARCH here.\n\n Other arch headers are created as needed on a per-arch basis.\"\n\nFixed up some conflicts from other header file cleanups and moving code\naround that has happened in the meantime, so David\u0027s testing is somewhat\nweakened by that.

Remove slab destructors from kmem_cache_create().\n\nSlab destructors were no longer supported after Christoph\u0027s\nc59def9f222d44bb7e2f0a559f2906191a0862d7 change. They\u0027ve been\nBUGs for both slab and slub, and slob never supported them\neither.\n\nThis rips out support for the dtor pointer from kmem_cache_create()\ncompletely and fixes up every single callsite in the kernel (there were\nabout 224, not including the slab allocator definitions themselves,\nor the documentation references).\n\nSigned-off-by: Paul Mundt \u003clethal@linux-sh.org\u003e\n" }, { "commit": "88be9f990fe70f0f177ef44a16a477599e91f825", "tree": "d48ed0c934fc20dc3f7cacfc3b1eca3058246b65", "parents": [ "de05a0cc2a2ae16eb8d8dbf88fe728ace45beb9a" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Tue Jun 05 10:42:27 2007 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Tue Jul 10 23:40:23 2007 -0400" }, "message": "NFS: Replace vfsmount and dentry in nfs_open_context with struct path\n\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "de05a0cc2a2ae16eb8d8dbf88fe728ace45beb9a", "tree": "363a6afc01a935d9e34b3559235687f8fec4d512", "parents": [ "44dd151d5c21234cc534c47d7382f5c28c3143cd" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Sun May 20 13:05:05 2007 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Tue Jul 10 23:40:23 2007 -0400" }, "message": "NFS: Minor read optimisation...\n\nSince PG_uptodate may now end up getting set during the call to\nnfs_wb_page(), we can avoid putting a read request on the wire in those\nsituations.\n\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "60945cb7c8377b727288275f21791914fe65311c", "tree": "eb84b18a1e590d3c56b3779b4e1d071b21fca2bc", "parents": [ "550facd138d8f6b0ca683c1e894b5cd0f381cb63" ], "author": { "name": "Nate Diller", "email": "nate.diller@gmail.com", "time": "Thu May 10 22:55:08 2007 -0700" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Mon May 14 19:33:45 2007 -0400" }, "message": "NFS: use zero_user_page\n\nUse zero_user_page() instead of the newly deprecated memclear_highpage_flush().\n\nSigned-off-by: Nate Diller \u003cnate.diller@gmail.com\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: \"J.
