2008-05-06Revert "uml: fix gcc problem"Linus Torvalds
This reverts commit 22eecde2f9034764a3fd095eecfa3adfb8ec9a98. Uli reports that it breaks UML on x86-64 with the Fedora 8 gcc (gcc 4.1.2), causing a crash on startup. See http://marc.info/?l=linux-kernel&m=121011722806093&w=2 for a trace.

2008-05-06x86: fix PAE pmd_bad bootup warningHugh Dickins
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.

2008-05-04x86: remove dell reboot dmi quirk board name matchBen
http://bugzilla.kernel.org/show_bug.cgi?id=10547 Newer Dell OptiPlex 745s hang before rebooting after 'sudo reboot'. A patch for some versions of the OptiPlex was proposed here -- http://lkml.org/lkml/2007/6/5/59 -- and is included in 2.6.23 and later kernels, according to http://lxr.linux.no/linux+v2.6.23/arch/i386/kernel/reboot.c . However, the DMI_BOARD_NAME ("0WF810") is too restrictive. Newer OptiPlex machines have a DMI_BOARD_NAME of "0RF703". I therefore suggest adding another clause to reboot.c, similar to the one in the original patch, but matching a DMI_BOARD_NAME of "0RF703". On further inspection, it seems that there are other DMI_BOARD_NAMEs for this same machine. They seem to change from time to time, which means that the current code is fragile. Moreover, using bios reboot should not break non-SFF OptiPlex 745s, and so a reasonable fix is to simply drop the match on DMI_BOARD_NAME.

2008-05-03unified (weak) sys_pipe implementationUlrich Drepper
This replaces the duplicated arch-specific versions of "sys_pipe()" with one unified implementation. This removes almost 250 lines of duplicated code. It's marked __weak, so that *if* an architecture wants to override the default implementation it can do so by simply having its own replacement version, since many architectures use alternate calling conventions for the 'pipe()' system call for legacy reasons (ie traditional UNIX implementations often return the two file descriptors in registers) I still haven't changed the cris version even though Linus says the BKL isn't needed.
