Valdis and all,
I understand we cannot access the same physical memory both as cacheable and
non-cacheable.
and I'm pretty sure they were pointing to the same physical address. (I have

Think for a bit how shared libraries are implemented. Then think about how
mmap() of a shared region of a file at different virt
In my previous email below, virtual address 0xc800 (for nocache region) and

Is this situation normal? (in the kernel, two different virtual addresses
pointing to the same physical address.)
Thanks in advance.
