BUG_ON in arch/x86/mm/init_32.c triggered: BUG_ON((unsigned long)high_memory > VMALLOC_START); It's due to the vm area hole. In include/asm-x86/pgtable_32.h: #define VMALLOC_OFFSET (8 * 1024 * 1024) #define VMALLOC_START (((unsigned long)high_memory + 2 * VMALLOC_OFFSET - 1) \ & ~(VMALLOC_OFFSET - 1)) There's several related point: 1. MAXMEM : (-__PAGE_OFFSET - __VMALLOC_RESERVE). The space after VMALLOC_END is included as well, I set it to (VMALLOC_END - PAGE_OFFSET - __VMALLOC_RESERVE) 2. VMALLOC_OFFSET is not considered in __VMALLOC_RESERVE fixed by adding VMALLOC_OFFSET to it. 3. VMALLOC_START : (((unsigned long)high_memory + 2 * VMALLOC_OFFSET - 1) & ~(VMALLOC_OFFSET - 1)) So it's not always 8M, bigger than 8M possible. I set it to ((unsigned long)high_memory + VMALLOC_OFFSET) 4. the VMALLOC_RESERVE is an unused macro, so remove it here.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rusty, in his peevish way, complained that macros defining constants should have a name which somewhat accurately reflects the actual purpose of the constant. Aside from the fact that PTE_MASK gives no clue as to what's actually being masked, and is misleadingly similar to the functionally entirely different PMD_MASK, PUD_MASK and PGD_MASK, I don't really see what the problem is. But if this patch silences the incessent noise, then it will have achieved its goal (TODO: write test-case).

* x86: fix PAE pmd_bad bootup warningHugh Dickins2008-05-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix warning from pmd_bad() at bootup on a HIGHMEM64G HIGHPTE x86_32. That came from 9fc34113f6880b215cbea4e7017fc818700384c2 x86: debug pmd_bad(); but we understand now that the typecasting was wrong for PAE in the previous version: pagetable pages above 4GB looked bad and stopped Arjan from booting. And revert that cded932b75ab0a5f9181ee3da34a0a488d1a14fd x86: fix pmd_bad and pud_bad to support huge pages. It was the wrong way round: we shouldn't weaken every pmd_bad and pud_bad check to let huge pages slip through - in part they check that we _don't_ have a huge page where it's not expected. Put the x86 pmd_bad() and pud_bad() definitions back to what they have long been: they can be improved (x86_32 should use PTE_MASK, to stop PAE thinking junk in the upper word is good; and x86_64 should follow x86_32's stricter comparison, to stop thinking any subset of required bits is good); but that should be a later patch. Fix Hans' good observation that follow_page() will never find pmd_huge() because that would have already failed the pmd_bad test: test pmd_huge in between the pmd_none and pmd_bad tests. Tighten x86's pmd_huge() check? No, once it's a hugepage entry, it can get quite far from a good pmd: for example, PROT_NONE leaves it with only ACCESSED of the KERN_PGTABLE bits. However... though follow_page() contains this and another test for huge pages, so it's nice to keep it working on them, where does it actually get called on a huge page? get_user_pages() checks is_vm_hugetlb_page(vma) to to call alternative hugetlb processing, as does unmap_vmas() and others.

* x86: unify KERNEL_PGD_PTRSJeremy Fitzhardinge2008-04-24
| | | | | | | | | | | | | | | | | | | | | | | Make KERNEL_PGD_PTRS common, as previously it was only being defined for 32-bit. There are a couple of follow-on changes from this: - KERNEL_PGD_PTRS was being defined in terms of USER_PGD_PTRS. The definition of USER_PGD_PTRS doesn't really make much sense on x86-64, since it can have two different user address-space configurations. I renamed USER_PGD_PTRS to KERNEL_PGD_BOUNDARY, which is meaningful for all of 32/32, 32/64 and 64/64 process configurations. - USER_PTRS_PER_PGD was also defined and was being used for similar purposes. Converting its users to KERNEL_PGD_BOUNDARY left it completely unused, and so I removed it.

* x86: remove quicklistsThomas Gleixner2008-03-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | quicklists cause a serious memory leak on 32-bit x86, as documented at: http://bugzilla.kernel.org/show_bug.cgi?id=9991 the reason is that the quicklist pool is a special-purpose cache that grows out of proportion. It is not accounted for anywhere and users have no way to even realize that it's the quicklists that are causing RAM usage spikes. It was supposed to be a relatively small pool, but as demonstrated by KOSAKI Motohiro, they can grow as large as: Quicklists: 1194304 kB given how much trouble this code has caused historically, and given that Andrew objected to its introduction on x86 (years ago), the best option at this point is to remove them. [ any performance benefits of caching constructed pgds should be implemented in a more generic way (possibly within the page allocator), while still allowing constructed pages to be allocated by other workloads. ] Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>

The boot stops right after freeing the init memory." and while it's not clear exactly what triggers it, at this stage we're better off just reverting it while Ingo tries to figure out what went wrong.

* x86: fix pmd_bad and pud_bad to support huge pagesHans Rosenfeld2008-02-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I recently stumbled upon a problem in the support for huge pages. If a program using huge pages does not explicitly unmap them, they remain mapped (and therefore, are lost) after the program exits. I observed that the free huge page count in /proc/meminfo decreased when running my program, and it did not increase after the program exited. After running the program a few times, no more huge pages could be allocated. The reason for this seems to be that the x86 pmd_bad and pud_bad consider pmd/pud entries having the PSE bit set invalid. I think there is nothing wrong with this bit being set, it just indicates that the lowest level of translation has been reached. This bit has to be (and is) checked after the basic validity of the entry has been checked, like in this fragment from follow_page() in mm/memory.c: if (pmd_none(*pmd) || unlikely(pmd_bad(*pmd))) goto no_page_table; if (pmd_huge(*pmd)) { BUG_ON(flags & FOLL_GET); page = follow_huge_pmd(mm, address, pmd, flags & FOLL_WRITE); goto out; } Note that this code currently doesn't work as intended if the pmd refers to a huge page, the pmd_huge() check can not be reached if the page is huge. Extending pmd_bad() (and, for future 1GB page support, pud_bad()) to allow for the PSE bit being set fixes this. For similar reasons, allowing the NX bit being set is necessary, too. I have seen huge pages having the NX bit set in their pmd entry, which would cause the same problem. Signed-Off-By: Hans Rosenfeld <hans.rosenfeld@amd.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

* x86: don't special-case pmd allocations as muchJeremy Fitzhardinge2008-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | In x86 PAE mode, stop treating pmds as a special case. Previously they were always allocated and freed with the pgd. The modifies the code to be the same as 64-bit mode, where they are allocated on demand. This is a step on the way to unifying 32/64-bit pagetable allocation as much as possible. There is a complicating wart, however. When you install a new reference to a pmd in the pgd, the processor isn't guaranteed to see it unless you reload cr3. Since reloading cr3 also has the side-effect of flushing the tlb, this is an expense that we want to avoid whereever possible. This patch simply avoids reloading cr3 unless the update is to the current pagetable. Later patches will optimise this further.
