[Crash-utility] [PATCH] do not check sp if ip points to user space

Friday, 23 September 2011

If the task is a user program, the sp can be points to anywhere,
because we can modify sp in assembly.
For example:

.globl main
        .type   main, @function
main:

        finit
        subq $16, (%rsp)
        movq $0, (%rsp)
.loop:
        jmp .loop
