Subject: uml: sparse inlines gcc-4.{2,3} compilation hack

Hi!

Small ARCH=um SUBARCH=i386 .config is in attach.
How to fix properly such kind of miscompilation? (gcc-4.3.1)
Now I have to use hacks like this:

    uml: sparse inlines gcc-4.{2,3} compilation fix.

    Patch fixes stuff like this:

      CC      mm/filemap.o
    /mnt/ext/backup3/dev/git/linux-2.6/mm/filemap.c: In function '__generic_file_aio_write_nolock':
    /mnt/ext/backup3/dev/git/linux-2.6/mm/filemap.c:1838: sorry, unimplemented: inlining failed in call to 'generic_write_checks': function body not available
    /mnt/ext/backup3/dev/git/linux-2.6/mm/filemap.c:2390: sorry, unimplemented: called from here
    make[2]: *** [mm/filemap.o] Error 1
    make[1]: *** [mm] Error 2
