* We cannot use a bare sigtramp page for hppa-linux.

* Unlike other guests where we use the instructions at PC to validate
* an offset from SP, the hppa libgcc signal frame fallback unwinding uses
* the PC address itself to find the frame. This is due to the fact that
* the hppa grows the stack upward, and the frame is of unknown size.
*
* TODO: We should be able to use a VDSO to address this, by providing
* proper unwind info for the sigtramp code, at which point the fallback
* unwinder will not be used.
