Hi Dan,

Since next-20090623, the linux-next build (i386 allmodconfig) has failed
like this:

crypto/async_tx/async_xor.c: In function ‘async_xor_init’:
crypto/async_tx/async_xor.c:310: error: size of array ‘type name’ is negative

The failing line is this:

	BUILD_BUG_ON(sizeof(dma_addr_t) > sizeof(struct page *));

in async_xor_init() introduced by commit
0036731c88fdb5bf4f04a796a30b5e445fc57f54 ("async_tx: kill tx_set_src and
tx_set_dest methods") in Feb, 2008.

Bisecting in the next-20090623 tree pointed to commit
3c30a9ca1fb95214e60e3bf43957971df6668033 ("dmaengine: move HIGHMEM64G
restriction to ASYNC_TX_DMA") from the async_tx tree.  This is now commit
f3c56e57f66a73a241299dbec1ad55491aa0e403.

Gah, yes that commit was half baked.  I have pushed out an updated tree
with the following fix:

Thanks, I will include that update today.

Thanks for the report, I have pushed out a fix for this and some other
fallout from adding CONFIG_I7300_IDLE=y to my build tests.

Hi Dan,

Today's linux-next build (x86_64 allmodconfig) failed like this:

drivers/dma/ioat/dma_v2.c: In function 'ioat2_enumerate_channels':
drivers/dma/ioat/dma_v2.c:346: error: too few arguments to function 'i7300_idle_platform_probe'

Caused by commit feed1bce2e6dc7e3307f122ac95be6741840bee8 ("ioat2,3:
convert to a true ring buffer").

I have used the version of the async_tc tree from next-20090904 for today.
