    SubjectUser Mode Linux still broken in 2.6.23.1
    Date
    Building with the attached .config on x86-64, it does this:

    CC arch/um/kernel/smp.o
    In file included from include/asm/arch/tlb.h:11,
    from include/asm/tlb.h:4,
    from arch/um/kernel/smp.c:8:
    include/asm-generic/tlb.h: In function ‘tlb_flush_mmu’:
    include/asm-generic/tlb.h:76: error: implicit declaration of function ‘release_pages’
    include/asm-generic/tlb.h: In function ‘tlb_remove_page’:
    include/asm-generic/tlb.h:105: error: implicit declaration of function ‘page_cache_release’
    make[1]: *** [arch/um/kernel/smp.o] Error 1
    make: *** [arch/um/kernel] Error 2

    I've been doing the following to fix it. I know it's not the right fix,
    (see the earlier thread about it at http://lkml.org/lkml/2007/8/24/441 )
    but could the one line fix go into the -stable queue 2.6.23 while a proper
    fix goes into 2.6.24?

    From: Rob Landley <rob@landley.net>

    Fix build break in User Mode Linux 2.6.23.1.
