sparc64: Fix end-of-stack checking in save_stack_trace().
[ Upstream commit 433c5f706856689be25928a99636e724fb3ea7cf ]
Bug reported by Alexander Beregalov.
Before we dereference the stack frame or try to peek at the
pt_regs magic value, make sure the entire object is within
the kernel stack bounds.
