So here we go again. This time I am fairly confindent I got most things correct :) Also manged to use even less instructions in the TLB Miss handlers. Scott and Rex, forget previous versions and try this one out.
This patch set is better, userspace seems more stable but I am still
seeing some odd problems. This is from straceing mount, which displays
nothing even though /proc/mounts shows everything mounted properly:
open("/proc/mounts", O_RDONLY) = 3
fstat64(0x3, 0x7fe7e2a8) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x3001f000
read(3, 0x3001f000, 1024) = -1 EFAULT (Bad address)
exit_group(0) = ?
it looks like the memory allocated using mmap is bad?
take care!
