x86, 32-bit: fix kernel_trap_sp()
Use &regs->sp instead of regs for getting the top of stack in kernel mode. (on x86-64, regs->sp always points the top of stack) [ Impact: Oprofile decodes only stack for backtracing on i386 ] Signed-off-by: Masami Hiramatsu <mhiramat@redhat.com> [ v2: rename the API to kernel_stack_pointer(), move variable inside ] Acked-by: Linus Torvalds <torvalds@linux-foundation.org> Cc: systemtap@sources.redhat.com Cc: Harvey Harrison <harvey.harrison@gmail.com> Cc: Jan Blunck <jblunck@suse.de> Cc: Christoph Hellwig <hch@infradead.org> LKML-Reference: <20090511210300.17332.67549.stgit@localhost.localdomain> Signed-off-by: Ingo Molnar <mingo@elte.hu>
