The sleep_on function clears a running cqr without waiting for the related
interrupt. This can lead to a panic at the time the interrupt is processed
because the related memory might already be freed. Wait for clear-interrupt
and de-queue cqr prior to return.Signed-off-by: Horst Hummel

The return code of ccw_device_probe_console() is not properly handled. It
should only return a valid ccw device pointer or a error value converted by
ERR_PTR. Fix the console driver code to check with IS_ERR instead against
NULL.Signed-off-by: Peter Oberparleiter

Remove useless s390 define from hangcheck-timer, remove wrong definition of a
TOD second and other s390 ifdefs. Use monotonic_clock instead.Add hangcheck-timer option, copied from drivers/char/Kconfig. This is ugly
but unless we have a big Kconfig cleanup we cannot include
drivers/char/Kconfig...Signed-off-by: Jan Glauber

Add monotonic_clock interface, used by the hangcheck-timer. On s390 this is

The least significant bit of the TOD clock value returned by get_clock
is the 4096th part of a microsecond. To get to nanoseconds the value
needs to be divided by 4096 and multiplied with 1000.The current method multiplies first and then shifts the value to make the
result as precise as possible. The disadvantage is that the multiplication
with 1000 will overflow shortly after 52 days. sched_clock is used by the
scheduler for time stamp deltas, if an overflow occurs between two time stamps
the scheduler will get confused.With the patch the problem occurs only after approx. one year, so the chance
to run into this overflow is extremly low.Signed-off-by: Jan Glauber

- Remove all CVS generated information like e.g. revision IDs from
drivers/s390 and include/asm-s390 (none present in arch/s390).- Add newline at end of arch/s390/lib/Makefile to avoid diff message.

Olaf Hering
Olaf reported UML doesn't build for him with a clear analisys of what happened
- we're using NR_CPUS in files linked against glibc headers. Seems like it
defines CONFIG_SMP but not CONFIG_NR_CPUS, so we get CONFIG_NR_CPUS
undeclared.The fix is to move the declaration away from that header file and move it in
asm-um headers, and to add that header where needed.Signed-off-by: Paolo 'Blaisorblade' Giarrusso

In a recent fixup i386 code was copied raw to x86_64 subarch to make it
compile again.Here there are some little fixups and resyncs needed for it (mainly for
cleanliness sake) - I did an audit and found the rest of the code to be safe.Signed-off-by: Paolo 'Blaisorblade' Giarrusso

Fixes a bug introduced in commit e32dacb9f481fd6decb41adb28e720c923d34f54 -
index is initialized based on syscall before syscall is calculated.I'm bothering with this mainly because it gives a correct warning when the
config option is enabled, even if the code is for a almost unused debugging
option.Signed-off-by: Paolo 'Blaisorblade' Giarrusso

The C99 initialization, with GCC's bad handling, for 6K wide structs (which
_aren't_ on the stack), is causing GCC to use 12K for these silly procs with 3
vars. Workaround this.Note that .name = { '\0' } translates to memset(->name, 0, '->name' size) - I verified
this with GCC's docs and a testprogram.Signed-off-by: Paolo 'Blaisorblade' Giarrusso

This is a bug found by cpminer. The show_interrupts function reuses i as a
for loop counter, and therefore trashes its contents, which are needed
later.(akpm: rename local `i' to `irq', use for_each_inline_cpu())

Enable selection of different user/kernel VM splits for i386, including an
optimized mode for 1GB physical RAM, which gives the kernel a direct (non
HIGHMEM) mapping to the entire 1GB rather than just the first 896MB.There is a similarly a similarly optimized mode for machines with exactly 2GB
of physical RAM.This can speed up the kernel by avoiding having to create/destroy temporary
HIGHMEM mappings, and by not having to include HIGHMEM support at all on such
machines. The flip side is that there's less virtual addressing left for
userspace in these alternatives, and some binary-only kernel modules may
misbehave unless rebuilt with the same VMSPLIT option as the main kernel
image.Original idea/patch from Jens Axboe, modified based on suggestions from Linus
et al.Signed-off-by: Mark Lord
