quick questions: kernel stack size and call gates

2000-10-17 Thread Chris Swiedler
1. Does Linux use call gates (as specified in the Intel SDK vol.3) when a user process makes a system call? From what I understand, call-gates let a ring-3 process execute ring-0 code, which sounds exactly like a system call. I've found all of the actual system call functions (sys_ni etc.) in

I complained few days ago that 'agpgart.o' module from 2.2.18pre is causing a kernel oops. The problem turned out to be an apparent assumption that PCI memory <-> memory mapping is an identity and this is not always the case. Here is a patch applicable to all 2.2.18pre kernels with agpgart
