Impact: generalize the sw-IOTLB range checks
Some architectures require special rules to determine whether a range
needs mapping or not. This adds a weak function for architectures to
override.Signed-off-by: Ian Campbell

Impact: generalize physbusphys conversions in the swiotlb code
Architectures may need to override these conversions. Implement a
__weak hook point containing the default implementation.Signed-off-by: Ian Campbell

Impact: generalize swiotlb allocation code
Architectures may need to allocate memory specially for use with
the swiotlb. Create the weak function swiotlb_alloc_boot() and
swiotlb_alloc() defaulting to the current behaviour.Signed-off-by: Jeremy Fitzhardinge

A series of patches introduce a generic header file for the software
IO/TLB implementation in lib/swiotlb.c. Currently each architecture using
this code defines the prototypes itself. The prototypes are moved to
include/linux/swiotlb.h and this file is included in architecture specific
code for X86 and IA64.This patch:
Create include/linux/swiotlb.h file which contains all function prototypes
for the lib/swiotlb.c file.(akpm: the dependent patches will be trickled through arch trees)
