[PATCH 0/4] m68k/atari: Add ARAnyM support
This patch series add improved support for running under the ARAnyM emulator
(Atari Running on Any Machine - http://aranym.org/).
Without these patches, you can run a Linux/m68k kernel with Atari support
under ARAnyM (it emulates the IDE interface), but you can't have network and
console access.
This support has been in active use for several years. In fact some Debian
build daemons run under ARAnyM, as it's the fastest m68k platform around.
[1/4] m68k/atari: Initial ARAnyM support
[2/4] m68k/atari: ARAnyM - Add support for block access
[3/4] m68k/atari: ARAnyM - Add support for console access
[4/4] m68k/atari: ARAnyM - Add support for network access
Questions:
- Who should be listed as author for patches 1 and 4?
- Can I please have Signed-off-by's from the ARAnyM people?

Changelog:
- Wrap natfeat calls
Add wrappers with proper prototypes for the natfeat calls in nfblock.
This fixes the problem where sector_t was pushed on the stack as a 64-bit
value if CONFIG_LBDAF=y, while all parameters of the nf_call() varargs
function are 32-bit.
- Update for v2.6.31 block layer changes,
- nfblock needs linux/slab.h,
- Make needlessly global functions static,
- Make struct block_device_operations const,
- Use pr_*(),
- Propagate error code from register_blkdev().

Re: [PATCH 4/4] m68k/atari: ARAnyM - Add support for network access
From: Geert Uytterhoeven ge...@linux-m68k.org Date: Sun, 6 Feb 2011 11:51:09 +0100 + dev-trans_start = jiffies; Device drivers no longer make this operation, the generic code does it (see net/core/dev.c:dev_hard_start_xmit() and how it invokes txq_trans_update() on -ndo_start_xmit() success). Therefore, please remove this line. + pr_debug(DRV_NAME : send %d bytes\n, len); For consistency with other network drivers, add an appropriate CPP define for pr_fmt and use netdev_info(), netdev_debug(), etc. In situations where a netdev pointer is not available (ie. pre-register_netdev()), use dev_*() instead. Thanks. -- To unsubscribe from this list: send the line unsubscribe linux-m68k in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
