Some of these ops will be general to all x86, and some will be\n i386/x86-64 specific. This makes it easier to share common stuff\n while allowing separate implementations where needed.\n\n2. At the moment we must export all of paravirt_ops, but modules only\n need selected parts of it. This allows us to export on a case by case\n basis (and also choose which export license we want to apply).\n\n3. Functional groupings make things a bit more readable.\n\nStruct paravirt_ops is now only used as a template to generate\npatch-site identifiers, and to extract function pointers for inserting\ninto jmp/calls when patching. It is only instantiated when needed.\n\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy@xensource.com\u003e\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nCc: Zach Amsden \u003czach@vmware.com\u003e\nCc: Avi Kivity \u003cavi@qumranet.com\u003e\nCc: Anthony Liguory \u003caliguori@us.ibm.com\u003e\nCc: \"Glauber de Oliveira Costa\" \u003cglommer@gmail.com\u003e\nCc: Jun Nakajima \u003cjun.nakajima@intel.com\u003e\n" }, { "commit": "96a388de5dc53a8b234b3fd41f3ae2cedc9ffd42", "tree": "d947a467aa2da3140279617bc4b9b101640d7bf4", "parents": [ "27bd0c955648646abf2a353a8371d28c37bcd982" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Thu Oct 11 11:20:03 2007 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Thu Oct 11 11:20:03 2007 +0200" }, "message": "i386/x86_64: move headers to include/asm-x86\n\nMove the headers to include/asm-x86 and fixup the\nheader install make rules\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "5311ab62cdc7788784971ed816ce85e926f3e994", "tree": "08ceda3c1bbdc6c403107f5329d775c772b752ce", "parents": [ "90caccb9758e88db68a69553689baee38254287b" ], "author": { "name": "Jeremy Fitzhardinge", "email": "jeremy@goop.org", "time": "Wed May 02 19:27:13 2007 +0200" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Wed May 02 19:27:13 2007 +0200" }, "message": "[PATCH] i386: PARAVIRT: Allow paravirt backend to choose kernel PMD sharing\n\nNormally when running in PAE mode, the 4th PMD maps the kernel address space,\nwhich can be shared among all processes (since they all need the same kernel\nmappings).\n\nXen, however, does not allow guests to have the kernel pmd shared between page\ntables, so parameterize pgtable.c to allow both modes of operation.\n\nThere are several side-effects of this. One is that vmalloc will update the\nkernel address space mappings, and those updates need to be propagated into\nall processes if the kernel mappings are not intrinsically shared. In the\nnon-PAE case, this is done by maintaining a pgd_list of all processes; this\nlist is used when all process pagetables must be updated. pgd_list is\nthreaded via otherwise unused entries in the page structure for the pgd, which\nmeans that the pgd must be page-sized for this to work.\n\nNormally the PAE pgd is only 4x64 byte entries large, but Xen requires the PAE\npgd to page aligned anyway, so this patch forces the pgd to be page\naligned+sized when the kernel pmd is unshared, to accomodate both these\nrequirements.\n\nAlso, since there may be several distinct kernel pmds (if the user/kernel\nsplit is below 3G), there\u0027s no point in allocating them from a slab cache;\nthey\u0027re just allocated with get_free_page and initialized appropriately. (Of\ncourse the could be cached if there is just a single kernel pmd - which is the\ndefault with a 3G user/kernel split - but it doesn\u0027t seem worthwhile to add\nyet another case into this code).\n\n[ Many thanks to wli for review comments. ]\n\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy@xensource.com\u003e\nSigned-off-by: William Lee Irwin III \u003cwli@holomorphy.com\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nCc: Zachary Amsden \u003czach@vmware.com\u003e\nCc: Christoph Lameter \u003cclameter@sgi.com\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\n" }, { "commit": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "tree": "0bba044c4ce775e45a88a51686b5d9f90697ea9d", "parents": [], "author": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "message": "Linux-2.6.12-rc2\n\nInitial git repository build.
