4bdf8bc4a1 uml: borrow const.h techniques
Suggested by Geert Uytterhoeven - use const.h to get constants that are usable
in both C and assembly.  I can't include it directly since this code can't
include kernel headers.  const.h is also for numeric constants that can be
typed by tacking a "UL" or similar on the end.  The constants here have to be
typed by casting them.

So, the relevant parts of const.h are copied here and modified in order to
allow the constants to be uncasted in assembly and casted in C.

9226b83847 uml: further bugs.c tidying
bugs.c, for both i386 and x86_64, can undergo further cleaning -
	The i386 arch_check_bugs only does one thing, so we might as
well inline the cmov checking.
	The i386 includes can be trimmed down a bit.
	arch_init_thread wasn't used, so it is deleted.
	The panics in arch_handle_signal are turned into printks
because the process is about to get segfaulted anyway, so something is
dying no matter what happens here.  Also, the return value was always
the same, so it contained no information, so it can be void instead.
The name is changed to arch_examine_signal because it doesn't handle
anything.
	The caller of arch_handle_signal, relay_signal, does things in
a different order.  The kernel-mode signal check is now first, which
puts everything else together, making things a bit clearer conceptually.

that are kernel text.  The second one which isn't in the scheduler is the one
that's returned.  The first one is ignored because that will be UML's own

The pgd/pud/pmd/pte page table allocation functions get a mm_struct pointer as
first argument.  The free functions do not get the mm_struct argument.  This
is 1) asymmetrical and 2) to do mm related page table allocations the mm
argument is needed on the free function as well.

4dbed85a35 uml: stop gdb from deleting breakpoints when running UML
Sometimes when UML is debugged gdb miss breakpoints.

When process traced by gdb do fork, debugger remove breakpoints from
child address space. There is possibility to trace more than one fork,
but this not work with UML, I guess (only guess) there is a deadlock -
gdb waits for UML and UML waits for gdb.

When clone() is called with SIGCHLD and CLONE_VM flags, gdb see this
as PTRACE_EVENT_FORK not as PTRACE_EVENT_CLONE and remove breakpoints
from child and at the same time from traced process, because either
have the same address space.

Maybe it is possible to do fix in gdb, but I'm not sure if there is
easy way to find out if traced and child processes share memory. So I
do fix for UML, it simply do not call clone() with both SIGCHLD and
CLONE_VM flags together.  Additionally __WALL flag is used for
waitpid() to assure not miss clone and normal process events.

(d30f53aeb3) to move a call to netif_rx(skb)

This was found using the following semantic match.

364e3a3d8a uml: fix !NO_HZ busy-loop
With NO_HZ disabled, the UML idle loop effectively becomes a busy loop, as
it will sleep for no time.

The cause was forgetting to restart the tick after waking up from sleep.
It was disabled before sleeping, and the remaining time used as the
interval to sleep.  So, the tick needs to be restarted when nanosleep
finishes.

This is done by introducing after_sleep_interval, which is empty in the
NO_HZ case, but which sets the tick starting in the !NO_HZ case.
