[parisc-linux] Mysterious hangs with parisc (a send_group_sig_info() analysis)

[Carlos O'Donell]

>         Q4: imho the most important: with 2 gcc where is the couple of ssm/rsm that jejb introduced in his patch:

The *most* important piece of imformation is the pre-compiled source.
You *must* determine that both paths of the if/else are different,
because if they are the same, then GCC is right to remove one of the
paths, and unconditionally call cpu_relax.

Where is the pre-compiled source to prove that the paths aren't identical?

Remember to work towards a solution!

Cheers,
Carlos.
