s390 tt-mode needs to save not only syscall number, but an
further register also.

I accidentally included include/asm-um/elf.h as a real file in a previous
patch. This patch eliminates it.

tt-mode closes switch_pipes in exit_thread_tt and kills
processes in switch_to_tt, if the exit_state is
EXIT_DEAD or EXIT_ZOMBIE.
In very rare cases the exiting process can be scheduled out
after having set exit_state and closed switch_pipes (from

tt/mem.c still uses hardcoded TOP for i386 instead of
CONFIG_TOP_ADDR provided by subarch's Kconfig_,
which would be right.

So, there I was, looking at my own code, wondering what the magic setjmp
return values did. This patch turns the constants that are used to make
requests of the initial thread into meaningful symbols.

Command line handling cleanups - a couple of things made static and an

This fixes some x86_64 bugs -
maybe_map returns -1 on error instead of 0, which is interpretted as
physical address 0
removed an include of ipc.h, which isn't needed
fixed the calculation of signal frame location
the signal delivery code is now immune to the stack expansion check
From: Bodo Stroesser <[EMAIL PROTECTED]>
Only x86 and x86_64 use arch_align_stack(), all other subarches
have:
#define arch_align_stack(x) (x)
So, if this definition is found, UML's own arch_align_stack()
should be skipped.

Remove the __deprecated from verify_area_skas and verify_area_tt. Since
verify_area is itself marked __deprecated, and it is the only caller of
these, then they don't need to be marked. Marking them only makes the
build noisier.

s390 needs to change some parts of arch/um/kernel/ptrace.c.
Thus, the code regarding PEEKUSER and POKEUSER are shifted
to arch/um/sys-/ptrace.c.
Also s390 debug registers need to be updated, when
singlestepping is switched on / off. Thus, setting/resetting

No. The patch shifts code only, but AFAICS it doesn't alter the bahavior of
