Any recent updates to those patches?
Not since I sent the bunch to Christian for inclusion in the Debian
kernels. I thought I had sent them to debian-68k as well at the same time,
but I may be wrong there. The last stuff was the EtherNEC; I did some more
dead code cleanup on atafb but there's the modedb cleanup I'd like to get
done before posting a final patch.
I see Roman updated CVS to 2.6.19 so I'll pull a fresh copy and start on
that now.
Well, I've spent a little time to update my Atari patches to 2.6.19-m68k.
There's two details I'd need some advice on - lockdep for the case where
CONFIG_GENERIC_HARDIRQS is not set, and a small fix for scsi_lib. First
lockdep:
drivers/net/8390.c calls disable_irq_nosync_lockdep_irqsave and
enable_irq_lockdep_irqrestore in 2.6.19 now. The EtherNEC driver uses
8390.c so we need these functions on m68k now. I've just added dummy
declarations to make them behave as their non-lockdep counterparts for
now. Can m68k set CONFIG_GENERIC_HARDIRQS?

The second item concerns a warning given for each SCSI target scanned on
the Falcon, where sg_tablesize is set to SG_NONE (aka zero). The
blk_queue_max_hw_segments() call should set a minimum size of one
regardless of the sg_tablesize value (blk_queue_max_hw_segments() corrects
this and gives a warning).

This one should go directly upstream, I think.
Comments, anyone?
