This avoids having to maintain a separate\nenum for patch site types.\n\nAlso, since the identifier is derived from the offset into\nparavirt_ops, the offset can be derived from the identifier. This is\nused to remove replicated information in the various callsite macros,\nwhich has been a source of bugs in the past.\n\nThis patch also drops the fused save_fl+cli operation, which doesn\u0027t\nreally add much and makes things more complex - specifically because\nit breaks the 1:1 relationship between identifiers and offsets. If\nthis operation turns out to be particularly beneficial, then the right\nanswer is to define a new entrypoint for it.\n\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy@xensource.com\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nCc: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nCc: Zachary Amsden \u003czach@vmware.com\u003e\n" }, { "commit": "98de032b681d8a7532d44dfc66aa5c0c1c755a9d", "tree": "7e36cf682a113354427ad1076b38d0c3d0aebd8c", "parents": [ "d6dd61c831226f9cd7750885da04d360d6455101" ], "author": { "name": "Jeremy Fitzhardinge", "email": "jeremy@goop.org", "time": "Wed May 02 19:27:14 2007 +0200" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Wed May 02 19:27:14 2007 +0200" }, "message": "[PATCH] i386: PARAVIRT: rename struct paravirt_patch to paravirt_patch_site for clarity\n\nRename struct paravirt_patch to paravirt_patch_site, so that it\nclearly refers to a callsite, and not the patch which may be applied\nto that callsite.\n\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy@xensource.com\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nCc: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nCc: Zachary Amsden \u003czach@vmware.com\u003e\n" }, { "commit": "d6dd61c831226f9cd7750885da04d360d6455101", "tree": "30f84a429821d207f7de5dd6225d3d9515042c0a", "parents": [ "5311ab62cdc7788784971ed816ce85e926f3e994" ], "author": { "name": "Jeremy Fitzhardinge", "email": "jeremy@goop.org", "time": "Wed May 02 19:27:14 2007 +0200" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Wed May 02 19:27:14 2007 +0200" }, "message": "[PATCH] x86: PARAVIRT: add hooks to intercept mm creation and destruction\n\nAdd hooks to allow a paravirt implementation to track the lifetime of\nan mm.

When\nthe VM subsystem is initialized, it creates a proper pagetable which\nrespects the PAE mode, large pages, etc.\n\nWhen booting under a hypervisor, there are many possibilities for what\npaging environment the hypervisor establishes for the guest kernel, so\nthe constructon of the kernel\u0027s pagetable depends on the hypervisor.\n\nIn the case of Xen, the hypervisor boots the kernel with a fully\nconstructed pagetable, which is already using PAE if necessary. Also,\nXen requires particular care when constructing pagetables to make sure\nall pagetables are always mapped read-only.\n\nIn order to make this easier, kernel\u0027s initial pagetable construction\nhas been changed to only allocate and initialize a pagetable page if\nthere\u0027s no page already present in the pagetable. This allows the Xen\nparavirt backend to make a copy of the hypervisor-provided pagetable,\nallowing the kernel to establish any more mappings it needs while\nkeeping the existing ones.\n\nA slightly subtle point which is worth highlighting here is that Xen\nrequires all kernel mappings to share the same pte_t pages between all\npagetables, so that updating a kernel page\u0027s mapping in one pagetable\nis reflected in all other pagetables. This makes it possible to\nallocate a page and attach it to a pagetable without having to\nexplicitly enumerate that page\u0027s mapping in all pagetables.\n\nAnd:\n\n+From: \"Eric W.

COMPAT_VDSO maps the VDSO at\na specific system-wide fixed address. Previously this was all done at\nbuild time, on the grounds that the fixed VDSO address is always at\nthe top of the address space. However, a hypervisor may reserve some\nof that address space, pushing the fixmap address down.\n\nThis patch does the adjustment dynamically at runtime, depending on\nthe runtime location of the VDSO fixmap.\n\n[ Patch has been through several hands: Jan Beulich wrote the orignal\n version; Zach reworked it, and Jeremy converted it to relocate phdrs\n as well as sections. ]\n\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy@xensource.com\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nCc: Zachary Amsden \u003czach@vmware.com\u003e\nCc: \"Jan Beulich\" \u003cJBeulich@novell.com\u003e\nCc: Eric W.

The technique used is to\ncompile the decompressor with -fPIC and modify it so the decompressor\nis fully relocatable. For the main kernel the page tables are\nmodified so the kernel remains at the same virtual address. In\naddition a variable phys_base is kept that holds the physical address\nthe kernel is loaded at. __pa_symbol is modified to add that when\nwe take the address of a kernel symbol.\n\nWhen loaded with a normal bootloader the decompressor will decompress\nthe kernel to 2M and it will run there. This both ensures the\nrelocation code is always working, and makes it easier to use 2M\npages for the kernel and the cpu.\n\nAK: changed to not make RELOCATABLE default in Kconfig\n\nSigned-off-by: Eric W.

This is especially true with a relocatable kernel as\n__pa_symbol needs to peform an extra variable read to resolve\nthe address.\n\nThere is a third macro that is added for the vsyscall data\n__pa_vsymbol for finding the physical addesses of vsyscall pages.\n\nMost of this patch is simply sorting through the references to\n__pa or __pa_symbol and using the proper one. A little of\nit is continuing to use a physical address when we have it\ninstead of recalculating it several times.\n\nswapper_pgd is now NULL. leave_mm now uses init_mm.pgd\nand init_mm.pgd is initialized at boot (instead of compile time)\nto the physmem virtual mapping of init_level4_pgd.
