[PATCH] parisc: define SRCARCH=parisc for parisc64 builds

[Helge Deller]

The parisc64 target (HP PARISC, 64bit kernel) is similar to the sparc64 or 
m68knommu targets, as it shares all sources for 32- and 64-bit in one single
source path which is arch/parisc/.
This patch now allows one to use ARCH=parisc64 and just directly build the
64bit kernel without creating symlinks in arch/ and include/asm-* manually
the same way as it's done for sparc64 and m68knommu.

I'm going to drop this patch, powerpc and mips don't do it, and
'parisc64' hasn't been valid as $ARCH since v2.3 or something equally
ancient, so I can't see any point in it.

=C4h ?
And how do you build a 64bit parisc kernel then ?

CONFIG_64BIT.

No, this does not work with a cleanly checked-out tree.
Just remove the arch/parisc64 link which you created manually.

It's simple, set CONFIG_64BIT, and just call it 'parisc' like
everyone else has done for years now.

Thanks for the offer, Kyle.
But I think I can easily change my scripts, so it's not necessary.
