Al Viro 325a80715f ipg: endianness fixes
if your mask is host-endian, you should apply it after le64_to_cpu();
if it's little-endian - before.  Doing both (for the same mask and
little-endian value) is broken.

trem 1dad939ddb ipg.c doesn't compile with with CONFIG_HIGHMEM64G
I've tried to compile 2.6.23-rc8-mm2, but it fails on ipg.c with the
error : ERROR: "__udivdi3" [drivers/net/ipg.ko] undefined!

I've instigated a bit, and I've found this code in ipg.c :

static void ipg_nic_txfree(struct net_device *dev)
{
       struct ipg_nic_private *sp = netdev_priv(dev);
       void __iomem *ioaddr = sp->ioaddr;
       const unsigned int curr = ipg_r32(TFD_LIST_PTR_0) -
               (sp->txd_map / sizeof(struct ipg_tx)) - 1;
       unsigned int released, pending;

sp->txd_map is an u64
because :
	dma_addr_t txd_map;

And in asm-i386/types.h, I see :
#ifdef CONFIG_HIGHMEM64G
typedef u64 dma_addr_t;
#else
typedef u32 dma_addr_t;
#endif
I my config, I use CONFIG_HIGHMEM64G

sizeof(struct ipg_tx) is an u32
So the div failed on i386 because of u64 / u32.
