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:

The open_count is increased for every opener, that includes the blkdev_get in dasd_scan_partitions. This tampers the open_count in BIODASDINFO. Hide the internal open from user-space. Signed-off-by:

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:

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:

Add monotonic_clock interface, used by the hangcheck-timer. On s390 this is the same as sched_clock(). Signed-off-by:

Jan Glauber authored
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:

- 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. Acked-by:

Olaf Hering <olh@suse.de> 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.

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:

Fixes a bug introduced in commit e32dacb9 - 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:

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: -

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()) Signed-off-by:

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.

machine_halt() managed to trigger the soft lockup detection due to not disabling interrupts before going to sleep, so correct that. machine_power_off() should be using pm_power_off, which lets us drop the board-specific hacks from here. Signed-off-by:

Trivial patch updating the voyagergx cchip code to reference a platform device instead, now that the dma mask is taken care of. Given this, there's no longer any reason to drag around the SH-bus code, so kill that off entirely. Signed-off-by:
