kfraser@localhost.localdomain 576a882bc5 [LINUX] dma: Use swiotlb mask for coherent mappings too 
The recent change to use a default DMA bit width of 30 bits (required
by chips like the b44) only converted the streaming DMA primitives.
The coherent mappings are still hard-coded to 31 bits.  This means
that b44 still doesn't work under Xen.

This patch makes the io_tlb_dma_bits variable global and uses it for
coherent memory mappings.

Thanks to Calvin Webster for providing a machine with a b44 and 2G
of memory I've been able to verify that this finally makes the b44
work under Xen.

Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Rename 'io_tlb_dma_bits' to the more correct 'dma_bits'. This also
affects the name of the boot parameter, which is now 'dma_bits='.

awilliam@xenbuild2.aw 5fb6147b15 [IA64] evtchn_callback fix and clean 
Since we had changed to use event callback to deliver interrupts,

1. The pending_interruption is changed to pending_event.

2. get_ivr, set_tpr, get_trp and set_eoi are not used or only used
   in the initialization phase. There is no need to write this code
   in assembly.  This code is deleted.

3. hyper_ssm_i needs to be rewritten to jump to entchn_callback_handler
   instead of iva+0x3000 interrupt handler.  I will do this later.
