David S. Miller	aa9143b971	[SPARC64]: Implement sun4v TSB miss handlers. When we register a TSB with the hypervisor, so that it or hardware can handle TLB misses and do the TSB walk for us, the hypervisor traps down to these trap when it incurs a TSB miss. Processing is simple, we load the missing virtual address and context, and do a full page table walk. Signed-off-by: David S. Miller <davem@davemloft.net>	2006-03-20 01:12:05 -08:00

[SPARC64]: Implement sun4v TSB miss handlers.

When we register a TSB with the hypervisor, so that it or hardware can
handle TLB misses and do the TSB walk for us, the hypervisor traps
down to these trap when it incurs a TSB miss.

Processing is simple, we load the missing virtual address and context,
and do a full page table walk.

[SPARC64]: Initial sun4v TLB miss handling infrastructure.

Things are a little tricky because, unlike sun4u, we have
to:

1) do a hypervisor trap to do the TLB load.
2) do the TSB lookup calculations by hand
