vsprintf: Introduce %pB format specifier ...
The %pB format specifier is for stack backtrace. Its handler
sprint_backtrace() does symbol lookup using (address-1) to
ensure the address will not point outside of the function.
If there is a tail-call to the function marked "noreturn",
gcc optimized out the code after the call then causes saved
return address points outside of the function (i.e. the start
of the next function), so pollutes call trace somewhat.
This patch adds the %pB printk mechanism that allows architecture
call-trace printout functions to improve backtrace printouts.
