.config changes should not appear in your patch file.

SAVE_FPR/REST_FPR definition style.
Caveats:
- Hard-float binaries which rely on in-kernel math emulation will give
wrong results since they expect 64-bit double-precision instead of 32-bit
single-precision numbers which Xilinx V4-FX Soft FPU produces.

Support the TXx9 SoC internal DMA controller. This can
have no objections. This sounds like a good plan.
Or we can put Xilinx-related headers to, i.e., include/linux/xilinx. There
might be some other candidates for this.

This code currently supports only soft MPMCs, i.e., only SDMA channels with
memory-mapped registers. In order to support channels with DCR, a few
modifications are needed.
Any comments and suggestions are appreciated.

Have a look at drivers/scsi/st.c at sgl_get_user_pages() or
drivers/infiniband/hw/ipath/ipath_user_pages.c for example of how to use that.

This fixes the missing acknowledge at the end of handle_level_irq().
It adds a field flags to struct irq_chip. If IRQ_CHIP_UNMASK_ACK is set in
this field, acknowledge is performed before unmasking.
