Hi,
I have a quick question.
The math_state_restore() restores the FPU/MMX/XMM states.
However where do we save the previous task's states if it is necessary?

{
struct thread_info *thread = current_thread_info();

The line-wrapping in most of the include/asm/pgtable.h pte test/set
macros looks horrible in my 80 column terminal. The following "test the
waters" patch is how I would like to see them laid out. I realize that
the braces don't adhere to CodingStyle but the advantage is (when taking
wrapping into

Once you start reformatting things please make sure the result version
matches the documented codingstyle. That would be:
static inline int pte_user(pte_t pte)
{
return (pte).pte_low & _PAGE_USER;
}

The nfsd holds the big kernel lock upon exit, when it really shouldn't.
Not to mention that this breaks Ingo's RT patch. This is a trivial fix
to release the lock.
Ingo, this patch also works with your kernel, and stops the problem with
nfsd.
Note, there's a "goto out;" where "out:" is right abov
This bug is quite subtle and only happens in a very interesting
situation where a real-time threaded process is in the middle of a
coredump when someone whacks it with a SIGKILL. However, this deadlock
leaves the system pretty hosed and you have to reboot to recover.
Not good for real-time priorit

Except nothing in the network stack is using fp - the use of FP inside the
