Woo, it's happening a lot
I suspect this can go wrong anywhere, but it happens to have been a
CBQ-triggered gettimeofday() while sending an arp that did it. (My ADSL
router pretty much bombs the poor damn machine with ARP packets all the
time.)

Restructure the stub management code to make it simpler.
syscall_stub_done is extracted from do_syscall_stub.
The counters are gone since I never looked at them.
The common code in run_syscall_stub and syscall_stub_data is extracted
into flush_syscalls.

UML's supposed nanosecond clock interacts badly with NTP when NTP
decides that the clock has drifted ahead and needs to be slowed down.
Slowing down the clock is done by decrementing the cycle-to-nanosecond
multiplier, which is 1. Decrementing that gives you 0 and time is
stopped.
This is fixed b
Lots of asm-*/futex.h call pagefault_enable and pagefault_disable,
which are declared in linux/uaccess.h, without including
linux/uaccess.h.
They all include asm/uaccess.h, so this patch replaces asm/uaccess.h
with linux/uaccess.h.
Compile-tested on sparc64, x86, ia64, mips, and powerpc.

Add the BLOCK dependency for RAW_DRIVER, to match what's in
drivers/char/Kconfig. Also, while we're there, update the alleged
obsolesence of RAW_DRIVER since it doesn't seem to be going away any
time soon.

Alarm delivery could be noticably late in the !CONFIG_NOHZ case
because lost ticks weren't being taken into account. This is now
treated more carefully, with the time between ticks being calculated
and the appropriate number of ticks delivered to the timekeeping system.

Here's the stuff I have accumulated for 2.6.26. Cleanups and fixes of
varying sizes.
Patch 8 fiddles the includes of a bunch of the asm/futex.h's, so isn't
UML-specific.

Reintroduce uml_kmalloc for the benefit of UML libc code. The
previous tactic of declaring __kmalloc so it could be called directly
from the libc side of the house turned out to be getting too intimate
with slab, and it doesn't work with slob.
So, the uml_kmalloc wrapper is back. It calls kmallo

The top of physical memory should be below the initial process stack,
not the top of the address space, at least for as long as the stack
isn't known to the kernel VM system and appropriately reserved.

This patch includes page.h header into liker scripts that
allow us to use PAGE_SIZE macro instead of numeric constant.
To be able to include page.h into linker scripts page.h is
needed for some modification - i.e. we need to use __ASSEMBLY__

The random driver would essentially hang if the host's /dev/random

to work anyway.
The right way is to ask for an interrupt when there is input available
