45807a1df9 vdso: print fatal signals
Add the print-fatal-signals=1 boot option and the
/proc/sys/kernel/print-fatal-signals runtime switch.

This feature prints some minimal information about userspace segfaults to
the kernel console.  This is useful to find early bootup bugs where
userspace debugging is very hard.

Defaults to off.

17973f5af7 Only send SIGXFSZ when exceeding rlimits.
Some users have been having problems with utilities like cp or dd dumping
core when they try to copy a file that's too large for the destination
filesystem (typically, > 4gb).  Apparently, some defunct standards required
SIGXFSZ to be sent in such circumstances, but SUS only requires/allows it
for when a written file exceeds the process's resource limits.  I'd like to
limit SIGXFSZs to the bare minimum required by SUS.

60bfba7e85 PIE randomization
This patch is using mmap()'s randomization functionality in such a way that
it maps the main executable of (specially compiled/linked -pie/-fpie)
ET_DYN binaries onto a random address (in cases in which mmap() is allowed
to perform a randomization).

Origin of this patch is in exec-shield

c3ed85a36f isofs: fix up CodingStyle
fs/isofs/* had a bunch of CodingStyle issues.
* Indentation was a mix of spaces and tabs
* "int * foo" instead of "int *foo"
* "while ( foo )" instead of "while (foo)"
* if (foo) blah; on one line instead of two
* Missing printk KERN_ levels
* lots of trailing whitespace
* lines >80 columns changed to wrap.
* Unnecessary prototype removed by shuffling code order in C file.

Should be no functional changes other than slight size increase due to
printk changes.  Further improvement possible, but this is a start..

c67ad917cb percpu_counters(): use cpu notifiers
per-cpu counters presently must iterate over all possible CPUs in the
exhaustive percpu_counter_sum().

But it can be much better to only iterate over the presently-online CPUs.  To
do this, we must arrange for an offlined CPU's count to be spilled into the
counter's central count.

We can do this for all percpu_counters in the machine by linking them into a
single global list and walking that list at CPU_DEAD time.

(I hope.  Might have race windows in which the percpu_counter_sum() count is
inaccurate?)

1c6b4aa945 cpu hotplug: fix ksoftirqd termination on cpu hotplug with naughty realtime process
Fix ksoftirqd termination on cpu hotplug with naughty real time process.

Assuming the following case:

 - Try to hot remove CPU2 from CPU1.
 - There is a real time process on CPU2, and that process doesn't sleep at all.
 - That rt process and ksoftirqd/2 is migrated to the CPU0

Then ksoftirqd/2 can't stop becasue that rt process runs everlastingly on
CPU0, and CPU1 waiting the ksoftirqd/2's termination hangs up.  To fix this
problem, set the priority of ksoftirqd/2 to max one before kthread_stop().

...  "kstopmachine" can't start to run and the CPU on which

7c3f1a5732 Introduce boot based time
The commits

  411187fb05 (GTOD: persistent clock support)
  c1d370e167 (i386: use GTOD persistent clock
    support)

changed the monotonic time so that it no longer jumps after resume, but it's
not possible to use it for boot time and process start time calculations then.
 Also, the uptime no longer increases during suspend.

I add a variable to track the wall_to_monotonic changes, a function to get the
real boot time and a function to get the boot based time from the monotonic
one.

Zhang, Yanmin
ed4aaadb1a fix jvc cdrom drive lockup
Before calling init_hwif_default, ide_unregister gets lock ide_lock and
disables irq.  init_hwif_default calls ide_default_io_base which calls
pci_get_device and later pci_get_subsys tries to apply for semaphore
pci_bus_sem and goes to sleep.

Mostly, pci_get_device should be called when irq is turned on.

ide_default_io_base just needs find if list pci_devices is empty.
