2005-09-28[SPARC64]: Simplify user fault fixup handling.David S. Miller
Instead of doing byte-at-a-time user accesses to figure out where the fault occurred, read the saved fault_address from the current thread structure. For the sake of defensive programming, if the fault_address does not fall into the user buffer range, simply assume the whole area faulted. This will cause the fixup for copy_from_user() to clear the entire kernel side buffer. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-09-28[SPARC64]: Fix fault handling in unaligned trap handler.David S. Miller
We were not calling kernel_mna_trap_fault() correctly. Instead of being fancy, just return 0 vs. -EFAULT from the assembler stubs, and handle that return value as appropriate. Create an "__retl_efault" stub for assembler exception table entries and use it where possible. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-09-28[SPARC64]: Convert to use generic exception table support.David S. Miller
The funny "range" exception table entries we had were only used by the compat layer socketcall assembly, and it wasn't even needed there. For free we now get proper exception table sorting and fast binary searching. Signed-off-by: David S. Miller <davem@davemloft.net>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
