Subject: PROBLEM: conflicting types for ‘sn_dma_flush’

Hi guys,
I had a problem in arch/ia64/include/asm/sn/io.h:
----------------------------------------------------------------------
arch/ia64/sn/pci/pcibr/pcibr_dma.c:237: error: conflicting types for 
‘sn_dma_flush’
/tmp/linux-2.6.33.2/arch/ia64/include/asm/sn/io.h:21: error: previous 
declaration of ‘sn_dma_flush’ was here
arch/ia64/sn/pci/pcibr/pcibr_dma.c:412: error: conflicting types for 
‘sn_dma_flush’
/tmp/linux-2.6.33.2/arch/ia64/include/asm/sn/io.h:21: error: previous 
declaration of ‘sn_dma_flush’ was here
CC arch/ia64/sn/kernel/huberror.o
make[4]: *** [arch/ia64/sn/pci/pcibr/pcibr_dma.o] Error 1
make[3]: *** [arch/ia64/sn/pci/pcibr] Error 2
make[2]: *** [arch/ia64/sn/pci] Error 2
make[2]: *** Waiting for unfinished jobs....
----------------------------------------------------------------------

Tested versions: 2.6.32.11, 2.6.33.2 also 2.6.34-rc5

arch/ia64/include/asm/sn/io.h:21:

extern void sn_dma_flush(unsigned long);

should be:

extern void sn_dma_flush(unsigned long long);

for:

arch/ia64/sn/pci/pcibr/pcibr_dma.c:237:

void sn_dma_flush(u64 addr)
{...}

After this change, works fine.
Cheers,
nevee
