[PATCH] Add comments to the PDA structure to annotate offsets

Browse Source 
Change the comments in the pda structure to make the first fields to have
their offset documented and to have the comments aligned.
The stack protector series needs a field at offset 40 (gcc ABI); annotate
upto 40 for that reason.
