It is not necessary to share the same notifier.h.
This patch already moves register_reboot_notifier() and
unregister_reboot_notifier() from kernel/notifier.c to kernel/sys.c.[amwang@redhat.com: make allyesconfig succeed on ppc64]

Linux can have pids up to 4*1024*1024. To handle such huge numbers

Until now UML had no x86_64 vDSO. So glibc always used the vsyscall page
for gettimeday() and friends. Calls to gettimeday() returned falsely the
host time and confused some programs.This patch adds a vDSO which turns all __vdso_* calls into a system call
so that UML can trap them.As glibc still uses the vsyscall page for static binaries this patch
improves the situation only for dynamic binaries.Signed-off-by: Richard Weinberger

Commit 0954828fcbf3 ("kconfig: replace KERNELVERSION usage by the
mainmenu's prompt") made the kernel version disappear from the generated
.config file when configuring for UML. As UML's Kconfig doesn't have a
mainmenu, kconfig falls back to the default string "Linux Kernel
Configuration".Add a suitable mainmenu to the main UML Kconfig file to fix this.

With the recent mmu_gather changes that included generic RCU freeing of
page-tables, it is now quite straightforward to implement gup_fast() on
sparc64.This patch:
Remove the page table quicklists. They are pointless and make it harder
to use RCU page table freeing and share code with other architectures.BTW, this is the second time this has happened, see commit 3c936465249f
