In this context, it means,\n\"the number of mmu pages which this kvm instance should be able to\nallocate.\" But \"free\" implies much more that the objects are there\nand ready for use. \"available\" is a much better description, especially\nwhen you see how it is calculated.\n\nIn this patch, we abstract its use into a function. We\u0027ll soon\nreplace the function\u0027s contents by calculating the value in a\ndifferent way.\n\nAll of the reads of n_free_mmu_pages are taken care of in this\npatch. The modification sites will be handled in a patch\nlater in the series.\n\nSigned-off-by: Dave Hansen \u003cdave@linux.vnet.ibm.com\u003e\nSigned-off-by: Tim Pepper \u003clnxninja@linux.vnet.ibm.com\u003e\nSigned-off-by: Avi Kivity \u003cavi@redhat.com\u003e\n" }, { "commit": "61429142802b068609ffd8ef48d891e05eeea0b9", "tree": "aecc86a8e81fcc5f858e0bc59cbb1ee34bcdd392", "parents": [ "d46164dbd936bc11c7d2abed62f05b31c7a79ae7" ], "author": { "name": "Avi Kivity", "email": "avi@redhat.com", "time": "Thu Aug 19 15:13:00 2010 +0300" }, "committer": { "name": "Avi Kivity", "email": "avi@redhat.com", "time": "Sun Oct 24 10:51:16 2010 +0200" }, "message": "KVM: x86 emulator: implement CWD (opcode 99)\n\nSigned-off-by: Avi Kivity \u003cavi@redhat.com\u003e\n" }, { "commit": "d46164dbd936bc11c7d2abed62f05b31c7a79ae7", "tree": "1947ea98edac4f7800d08b16dfe29509846759ef", "parents": [ "7db41eb76244ae623de842e818e459755968a33b" ], "author": { "name": "Avi Kivity", "email": "avi@redhat.com", "time": "Wed Aug 18 19:29:33 2010 +0300" }, "committer": { "name": "Avi Kivity", "email": "avi@redhat.com", "time": "Sun Oct 24 10:51:16 2010 +0200" }, "message": "KVM: x86 emulator: implement IMUL REG, R/M, IMM (opcode 69)\n\nSigned-off-by: Avi Kivity \u003cavi@redhat.com\u003e\n" }, { "commit": "7db41eb76244ae623de842e818e459755968a33b", "tree": "9661ee9702be3746bb52cbc9ca9d6e5bb4c8fc99", "parents": [ "39f21ee546cf7d563d813c5fb4473431c1d8fce7" ], "author": { "name": "Avi Kivity", "email": "avi@redhat.com", "time": "Wed Aug 18 19:25:28 2010 +0300" }, "committer": { "name": "Avi Kivity", "email": "avi@redhat.com", "time": "Sun Oct 24 10:51:15 2010 +0200" }, "message": "KVM: x86 emulator: add Src2Imm decoding\n\nNeeded for 3-operand IMUL.\n\nSigned-off-by: Avi Kivity \u003cavi@redhat.com\u003e\n" }, { "commit": "39f21ee546cf7d563d813c5fb4473431c1d8fce7", "tree": "0761137083bb141e1f48c711e0c424cb94842089", "parents": [ "48bb5d3c401679e41e7a7f06ca31b3e54a6168f7" ], "author": { "name": "Avi Kivity", "email": "avi@redhat.com", "time": "Wed Aug 18 19:20:21 2010 +0300" }, "committer": { "name": "Avi Kivity", "email": "avi@redhat.com", "time": "Sun Oct 24 10:51:14 2010 +0200" }, "message": "KVM: x86 emulator: consolidate immediate decode into a function\n\nSigned-off-by: Avi Kivity \u003cavi@redhat.com\u003e\n" }, { "commit": "48bb5d3c401679e41e7a7f06ca31b3e54a6168f7", "tree": "0dd588a481026f84755307fdc98fca155d353c5d", "parents": [ "7077aec0bcd2f827aeb84ccc56c6f4367c376436" ], "author": { "name": "Avi Kivity", "email": "avi@redhat.com", "time": "Wed Aug 18 18:54:34 2010 +0300" }, "committer": { "name": "Avi Kivity", "email": "avi@redhat.com", "time": "Sun Oct 24 10:51:14 2010 +0200" }, "message": "KVM: x86 emulator: implement RDTSC (opcode 0F 31)\n\nSigned-off-by: Avi Kivity \u003cavi@redhat.com\u003e\n" } ], "next": "7077aec0bcd2f827aeb84ccc56c6f4367c376436" }
