Unfortunately, because of various bugs and changes to the kernel,

we have several cases to deal with.

In 2.4, the signal trampoline is 4 bytes, and pc should point directly at

the beginning of the trampoline and struct rt_sigframe.

In <= 2.6.5-rc2-pa3, the signal trampoline is 9 bytes, and pc points at

the 4th word in the trampoline structure. This is wrong, it should point
|
||
at the 5th word. This is fixed in 2.6.5-rc2-pa4.
|

|

To detect these cases, we first take pc, align it to 64-bytes
|
||
to get the beginning of the signal frame, and then check offsets 0, 4
|
||
and 5 to see if we found the beginning of the trampoline. This will

tell us how to locate the sigcontext structure.
