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.

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.
