Hello,
Here is the last version of the patch updated regarding your remarks.
Regards,
Julien Krauth
Changes:
- Indentation.
- Code optimisation: all boards except the APCI-7800 are now managed
with the pci_default_setup() function.
- Add pbn_b0_8_115200 to manage the APCI-7800-3

This bug has been in the ACPICA interpreter since the beginning of time.
It is a reference-after-free bug due to the interpreter doing a

when the objects are part of a package.

This modifies do_wait and eligible_child to take a pair of
enum pid_type and struct pid *pid to precisely specify what
set of processes are eligible to be waited for, instead of the
raw pid_t value from sys_wait4.

The most complete should be :

It depends on the kernel trace thread flag patchset.

When the flag is inactive upon syscall entry and concurrently activated before
exit, we seem to reach a state where the top of stack is incorrect upon return
to user space.
Fix this by fixing the top of stack and jumping to int_ret_from_sys_call if we
detect that thread flags has been modified.

Hi,
This is an RFC for addition of a new thread flag, TIF_KERNEL_TRACE, to each
architecture to activate system-wide system call tracing.
This is needed by LTTng architecture dependent instrumentation.
It applies on 2.6.24-rc4-git3.

Add an API to set/clear the kernel wide tracing thread flags. Implemented in
kernel/sched.c. Updates thread flags *asynchronously* while holding the tasklist
lock.
Upon fork, the flag must be re-copied while the tasklist lock is held.

The port_mutex is actually a semaphore, so easily converted to
a struct mutex.

It's called stopmachine_mutex now, but it's a semaphore. So make it
a "struct mutex" .

Core kernel events.
*not* present in this patch because they are architecture specific :
- syscall entry/exit
- traps
- kernel thread creation

This patch adds several markers around semaphore primitives.
Along with a tracing application this patch can be useful for measuring
kernel semaphore usage and contention.

Hi,
This is the second RFC post for the LTTng architecture independent
instrumentation. I have mostly received interesting ideas from the mm group,
which I have added here.
It applies on top of 2.6.24-rc4-git3, on top of the Linux Kernel Markers with
Immediate Values patchset.

This patch is a hack to make my life easier : it lessens the conflicts due to
header includes that changes between the kernel versions.
The proper way to do this is to include in every file using the
markers.
NOT FOR UPSTREAM.

You are entitled to your opinion.
POSIX says nothing about the semantics of route resolution.

Since the breakpoint handler is useful both to kprobes and immediate values, it
makes sense to make the required restore_interrupt() available through
asm-i386/kdebug.h.
