The current method of printing out the trace is on every

Yes.
But this still leaves the fact that when someone says 'allyesconfig'
it's no longer clear which configuration he has. And no, I do not
consider it funny that this now

Hi!
the core of this patch series.
add /dev/mem_notify device for notification low memory to user process.
usage examle
fd = open(/dev/mem_notify, O_RDONLY);
if (fd 0) {
exit(1);
}
pollfds.fd = fd;
pollfds.events = POLLIN;

(Ingo, there is a question for you after the description, just before the
patch.)
When running an interrupt and network intensive stress test with PREEMPT_RT
enabled, the target system stopped processing received network packets.

This patch series is a few small fixes to kernel build errors for
the Toshiba RBTX4927 MIPS board in the 2.6.24-rc7 kernel, with the
2.6.24-rc7-rt2 patch previously applied. These patches are directly
related to the -rt2 patch, not to the vanilla MIPS tree.

This is probably just a temporary workaround for one procssor - the MIPS
community will most likely want to architect a solution to this issue.

Fix compile warning (which becomes compile error due to -Werror),
by changing from raw_spinlock_t to __raw_spinlock_t.

Hi Ingo,
More patches:
- rearrange paravirt.h to remove duplicate code, and to make it easy
to drop in 4th level pagetable functions.
- fix a warning I got from clear_bit in pgtable.h
- fix up some bogosity in pte_modify
- mask NX from pte_pfn
The last two may help with the problem that
In 32-bit PAE, mask NX from pte_pfn, since it isn't part of the PFN.
This code is due for unification anyway, but this fixes a latent bug.
