This reverts commit b94b08081fcecf83fa690d6c5664f6316fe72208.

genksyms currently cannot handle complicated types for exported
percpu variables.  Drop this patch for now as it prevents a
module from being loaded on sn2 systems:

 xpc: no symbol version for per_cpu____sn_cnodeid_to_nasid
 xpc: Unknown symbol per_cpu____sn_cnodeid_to_nasid

[IA64] Require SAL 3.2 in order to do extended config space ops

We had assumed that SAL firmware would return an error if it didn't
understand extended config space.  Unfortunately, the SAL on the SGI 750
doesn't do that, it panics the machine.  So, condition the extended PCI
config space accesses on SAL revision 3.2.

Registers are not saved anywhere when INIT comes during fsys mode and
we cannot know what happened when we investigate vmcore captured by
kdump. This patch adds new function finish_pt_regs() so registers can
be saved in such a case.

Bound the wait time for the ptcg_sem by using similar idea to the
ticket spin locks.  In this case we have only one instance of a
spinaphore, so make it 8 bytes rather than try to squeeze it into
4-bytes to keep the code simpler (and shorter).
