Subject: Using PAT features from user space

Hi everyone,
I'm writing an high performance application on x86-64 that allocate
some memory to store a write only journal. I was wondering if there is
a way to ask the kernel to mark such pages as write combining memory.
More in general, it's possible to use PAT from userspace? I was
expecting some mmap flag like MAP_NOCACHE, but there not seems to be
any such flags.
Regards,
Alessandro
