Having already merged the ppc and ppc64 versions of signal.c, this
patch finishes the job by merging signal.h.  The two versions were
almost identical already.  Notable changes:
	- We use BITS_PER_LONG to correctly size sigset_t
	- Remove some uneeded #includes and struct forward
declarations.  This does mean adding an include to signal_32.c which
relied on the indirect inclusion of sigcontext.h
	- As the ppc64 version, the merged signal.h has prototypes for
do_signal() and do_signal32().  Thus remove extra prototypes from
ppc_ksyms.c which had them directly.

Built and booted on POWER5 LPAR (ARCH=ppc64 and ARCH=powerpc).  Built
for 32-bit powermac (ARCH=ppc and ARCH=powerpc) and Walnut (ARCH=ppc).

AGP shouldn't use "global_flush_tlb()" to flush the AGP mappings, that i
spurely an x86'ism.  The proper AGP mapping flusher that should be used
is "flush_agp_mappings()", which on x86 obviously happens to do a global
TLB flush.

This makes AGP (or at least the config _I_ happen to use) compile again
on ppc64.

Currently connection tracking handles ICMP error like normal packets
if it failed to get related connection. But it fails that after all.

This makes connection tracking stop tracking ICMP error at early point.

Without this patch, any user can cause nfnetlink subsystems to be
autoloaded.  Those subsystems however could add significant processing
overhead to packet processing, and would refuse any configuration messages
from non-CAP_NET_ADMIN processes anyway.

This patch follows a suggestion from Patrick McHardy.

The reply tuple of the PNS->PAC expectation was using the wrong call id.

So we had the following situation:
- PNS behind NAT firewall
- PNS call id requires NATing
- PNS->PAC gre packet arrives first

then the PNS->PAC expectation is matched, and the other expectation
is deleted, but the PAC->PNS gre packets do not match the gre conntrack
because the call id is wrong.

We also cannot use ip_nat_follow_master().

The current sync_action for an array can be one of

   idle  - nothing happening
   resync - reduncancy being recalcualted
   recover - missing device being recoverred to spare
   check   - user initiated check of redundancy
   repair  - like resync but user-initiated and ignores
             bitmap optimisation.

Each of these strings can also be written to the 'sync_action' file to cause
that action to happen (if appropriate).

While 'sync' is not technically correct, as a recovery is *not* a 'sync', I
think it is the most servicable word here.  Also 'action' is a strong word
than 'mode'.
