sparc64: Properly truncate pt_regs framepointer in perf callback.
For 32-bit processes, we save the full 64-bits of the regs in pt_regs. But unlike when the userspace actually does load and store instructions, the top 32-bits don't get automatically truncated by the cpu in kernel mode (because the kernel doesn't execute with PSTATE_AM address masking enabled). So we have to do it by hand. Reported-by: Frederic Weisbecker <fweisbec@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
