Merge branch 'x86/um-header' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
* 'x86/um-header' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (26 commits) x86: canonicalize remaining header guards x86: drop double underscores from header guards x86: Fix ASM_X86__ header guards x86, um: get rid of uml-config.h x86, um: get rid of arch/um/Kconfig.arch x86, um: get rid of arch/um/os symlink x86, um: get rid of excessive includes of uml-config.h x86, um: get rid of header symlinks x86, um: merge Kconfig.i386 and Kconfig.x86_64 x86, um: get rid of sysdep symlink x86, um: trim the junk from uml ptrace-*.h x86, um: take vm-flags.h to sysdep x86, um: get rid of uml asm/arch x86, um: get rid of uml highmem.h x86, um: get rid of uml unistd.h x86, um: get rid of system.h -> system.h include x86, um: uml atomic.h is not needed anymore x86, um: untangle uml ldt.h x86, um: get rid of more uml asm/arch uses x86, um: remove dead header (uml module-generic.h; never used these days) ...
