This patch implements forwarding of SHUTDOWN intercepts from the guest

a triple fault (e.g. on reboot). This also fixes the bug that a guest

Hi,
I tried to call the following code in a kernel module:

I exported the function do_path_lookup() using

Hello,
I have written a kernel module which introduces a new subsystem in
sysfs, and it contains several attributes, one of which is binary. So
far, I've been testing it using text. My problem is, attempting to read
data continues forever. For example:

These patches allow the binaries which absolutely require that
their address space layout to be unaffected by address space
randomisation to specify that in their ELF header.
The first part defines the ELF header flag, the second implements
the corresponding part of the interpreter functionality.

Improve kernel/hrtimers.c locking: use a per-CPU base with a lock to
control locking of all clocks belonging to a CPU. This simplifies code
that needs to lock all clocks at once. This makes life easier for
high-res timers and dyntick.

The NMI watchdog implementation assumes that the local APIC timer
interrupt is happening. This assumption is not longer true when high
resolution timers and dynamic ticks come into play, as they may switch
off the local APIC timer completely. Take the PI

The TSC needs to be verified against another clocksource. Instead of
using hardwired assumptions of available hardware, provide a generic

The code which keeps track of jiffies and handles the long idle

The local apic timer calibration has two problem cases:
1. The calibration is based on readout of the PIT/HPET timer to detect the

>From what I can tell the Geode can safely use the TSC for highres, since:
1) Does not support frequency scaling,
2) The TSC _does_ count when the CPU is halted. Furthermore, the Geode
supports a mode called "suspension on halt", where Suspend mode (which

The tick-management code is the first user of the clockevents layer.
It takes clock event devices from the clock events core and uses them
