2012-08-08s390: do not clobber personality flags in sys_32_personality()Jiri Kosina1-4/+5
There are multiple errors in how sys_32_personality() handles personality flags stored in top three bytes. - directly comparing current->personality against PER_LINUX32 doesn't work in cases when any of the personality flags stored in the top three bytes are used. - directly forcefully setting personality to PER_LINUX32 or PER_LINUX discards any flags stored in the top three bytes Fix the first one by properly using personality() macro to compare only PER_MASK bytes. Fix the second one by setting only the bits that should be set, instead of overwriting the whole value.

If the last block of the HSA is read, EVSTATE_ALL_STORED is returned by SCLP. Because of a missing break in the switch statement two trace entries are written in this case: "all stored" and "part stored". This patch adds the missing break and also adds a "fall through" comment to improve the readability.

2012-08-05time: Fix adjustment cleanup bug in timekeeping_adjust()Ingo Molnar1-14/+17
Tetsuo Handa reported that sporadically the system clock starts counting up too quickly which is enough to confuse the hangcheck timer to print a bogus stall warning. Commit 2a8c0883 "time: Move xtime_nsec adjustment underflow handling timekeeping_adjust" overlooked this exit path: } else return; which should really be a proper exit sequence, fixing the bug as a side effect. Also make the flow more readable by properly balancing curly braces.

2012-08-04vfs: kill write_super and sync_supersArtem Bityutskiy5-97/+0
Finally we can kill the 'sync_supers' kernel thread along with the '->write_super()' superblock operation because all the users are gone. Now every file-system is supposed to self-manage own superblock and its dirty state. The nice thing about killing this thread is that it improves power management. Indeed, 'sync_supers' is a source of monotonic system wake-ups - it woke up every 5 seconds no matter what - even if there were no dirty superblocks and even if there were no file-systems using this service (e.g., btrfs and journalled ext4 do not need it). So it was wasting power most of the time. And because the thread was in the core of the kernel, all systems had to have it. So I am quite happy to make it go away. Interestingly, this thread is a left-over from the pdflush kernel thread which was a self-forking kernel thread responsible for all the write-back in old Linux kernels. It was turned into per-block device BDI threads, and 'sync_supers' was a left-over. Thus, R.I.P, pdflush as well.

2012-08-03perf kvm: Use strtol for walking guestmount directoryDavid Ahern1-1/+9
Only want to process directories under the guestmnount directory that have a pid as a name (ie, all digits). Other entries in the guestmount directory should be ignored. There is already a check that requires the first character of each entry to be a digit, but atoi is used to convert the directory name to a pid. For example if guestmount contains a directory with the name 1foo, atoi converts it to a pid of 1 and a machine is created with a pid of 1. This is wrong; this directory really should be ignored. Use strtol to do that.

2012-08-03perf tool: Save cmdline from user in file header vs what is passed to recordDavid Ahern3-2/+12
A number of builtin commands process some user args and then pass the rest to cmd_record. cmd_record then saves argc/argv that it receives into the header of the perf data file. But this loses the arguments handled by the first command -- ie., the real command line from the user. This patch saves the command line as typed by the user rather than what was passed to cmd_record. As an example consider the command: $ perf kvm --guest --host --guestmount=/tmp/guest-mount record -fo /tmp/perf.data -ag -- sleep 10 Currently the command saved to the header is: cmdline : /tmp/p3.5/perf record -o perf.data.kvm -fo /tmp/perf.data -ag -- sleep 1 (ignore the duplicated -o -- the first would be yet another bug with perf-kvm). With this patch the command line saved to the header is: cmdline : /tmp/p3.5/perf kvm --guest --host --guestmount=/tmp/guest-mount record -fo /tmp/perf.data -ag -- sleep 1 v2: simplified to saving the command in parse_options per Stephane's suggestion Signed-off-by: David Ahern <[email protected]> Cc: Frederic Weisbecker <[email protected]> Cc: Ingo Molnar <[email protected]> Cc: Jiri Olsa <[email protected]> Cc: Namhyung Kim <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Stephane Eranian <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>
2012-08-03perf top: Error handling for counter creation should parallel perf-recordDavid Ahern1-2/+4
5a7ed29 fixed up perf-record but not perf-top. Similar argument holds for it -- fallback to PMU only if it does not exist and handle invalid attributes separately.

In commit 99b725084 "ACPI processor hotplug: Delay acpi_processor_start() call for hotplugged cores", acpi_processor_hotplug(pr) was wrongly replaced by acpi_processor_cst_has_changed() inside the acpi_cpu_soft_notify().
