Hi!
Just a short question: What is the correct method of copying large areas of
memory from userspace into userspace when running in kernel-mode?
According to just about any type of documentation out there something like
unsigned long *from = 0x0800;
unsigned long *to = 0x0900;
memcpy(to

Hi everyone!
I have a strange problem where I don't even know if there is a solution to it
at the moment:
I'm working on a new way of doing memory-management and currently I allocate

hi!
i'm working on a new concept of i386 memory management and have to change
