arcmsr: fix IRQs disabled warning spew
As of 2.6.24, running the archttp passthrough daemon with the arcmsr
driver produces an endless spew of dma_free_coherent warnings:
WARNING: at arch/x86/kernel/pci-dma_64.c:169 dma_free_coherent()
It turns out that coherent memory is not needed, so commit 76d78300 by
Nick Cheng <[EMAIL PROTECTED]> switched it to kmalloc (as well as
making a lot of other changes which have not been included here).
James Bottomley pointed out that the new kmalloc usage was also wrong,
I corrected this in commit 69e562c2.
This patch combines both of the above for the purpose of fixing 2.6.24.
