This includes the function\nargument registers, and several others.\n\nThis patch seeks to alleviate this pressure by introducing wrapper\nthunks that will do the register saving/restoring, so that the\ncallsite doesn\u0027t need to worry about it, but the callee function can\nbe conventional compiler-generated code. In many cases (particularly\nperformance-sensitive cases) the callee will be in assembler anyway,\nand need not use the compiler\u0027s calling convention.\n\nStandard calling convention is:\n\t arguments\t return\tscratch\nx86-32\t eax edx ecx\t eax\t\t?\nx86-64\t rdi rsi rdx rcx rax\t\tr8 r9 r10 r11\n\nThe thunk preserves all argument and scratch registers. The return\nregister is not preserved, and is available as a scratch register for\nunwrapped callee code (and of course the return value).\n\nWrapped function pointers are themselves wrapped in a struct\nparavirt_callee_save structure, in order to get some warning from the\ncompiler when functions with mismatched calling conventions are used.\n\nThe most common paravirt ops, both statically and dynamically, are\ninterrupt enable/disable/save/restore, so handle them first. This is\nparticularly easy since their calls are handled specially anyway.\n\nXXX Deal with VMI. What\u0027s their calling convention?\n\nSigned-off-by: H.

Oops is at [1].\n\nBisection led to the following commit:\n\ncommit 37cc8d7f963ba2deec29c9b68716944516a3244f\n\n x86/early_ioremap: don\u0027t assume we\u0027re using swapper_pg_dir\n\n At the early stages of boot, before the kernel pagetable has been\n fully initialized, a Xen kernel will still be running off the\n Xen-provided pagetables rather than swapper_pg_dir[]. Therefore,\n readback cr3 to determine the base of the pagetable rather than\n assuming swapper_pg_dir[].\n\n static inline pmd_t * __init early_ioremap_pmd(unsigned long addr)\n {\n-\tpgd_t *pgd \u003d \u0026swapper_pg_dir[pgd_index(addr)];\n+\t/* Don\u0027t assume we\u0027re using swapper_pg_dir at this point */\n+\tpgd_t *base \u003d __va(read_cr3());\n+\tpgd_t *pgd \u003d \u0026base[pgd_index(addr)];\n \tpud_t *pud \u003d pud_offset(pgd, addr);\n \tpmd_t *pmd \u003d pmd_offset(pud, addr);\n\nTrying to analyze the problem, it seems on the guest side of lguest,\n%cr3 has a different value from \u0026swapper_pg-dir (which\nis AFAIK fine on a pravirt guest):\n\nPutting some debugging messages in early_ioremap_pmd:\n\n/* Appears 3 times */\n[ 0.000000] ***************************\n[ 0.000000] __va(%cr3) \u003d c0000000, \u0026swapper_pg_dir \u003d c02cc000\n[ 0.000000] ***************************\n\nAfter 8 hours of debugging and staring on lguest code, I noticed something\nstrange in paravirt_ops-\u003eset_pmd hypercall invocation:\n\nstatic void lguest_set_pmd(pmd_t *pmdp, pmd_t pmdval)\n{\n\t*pmdp \u003d pmdval;\n\tlazy_hcall(LHCALL_SET_PMD, __pa(pmdp)\u0026PAGE_MASK,\n\t\t (__pa(pmdp)\u0026(PAGE_SIZE-1))/4, 0);\n}\n\nThe first hcall parameter is global pgdir which looks fine. The second\nparameter is the pmd index in the pgdir which is suspectful.\n\nAFAIK, calculating the index of pmd does not need a divisoin over four.\nRemoving the division made lguest work fine again . Patch is at [2].\n\nI am not sure why the division over four existed in the first place. It\nseems bogus, maybe the Xen patch just made the problem appear ?\n\n[2]: The patch:\n\n[PATCH] lguest: fix pgdir pmd index cacluation\n\nRemove an error in index calculation which leads to removing\na not existing shadow page table (leading to a Null dereference).\n\nSigned-off-by: Ahmed S.
