correct add 1 to the current size, gpuRange as gpuRange
only specifies the end address of the pool, not the actual
size, which causes alignment issue of all the offsets of
allocated objects. Also, a page was added in the beginning
of the limited range memory pool to avoid the base address
of it to be 0x0 that is interpreted as invalid address by
heap allocator (This makes the size reduced by pageSize)
Internal 32bit allocator is also initialized in proper way
with corrected base address.
v2: added 'givenMemoryManagerLimimedRangeAllocator' unit
test
v3: adjust size to be freed when DrmMemoryManager instance
is destroyed to 4GB
v4: - defined external 32bit allocator for limited Range
allocation case.
- softpinning object on the correct GPU address

Intel(R) Graphics Compute Runtime for OpenCL(TM)
Introduction
The Intel(R) Graphics Compute Runtime for OpenCL(TM) is a open source project to converge Intel's development efforts on OpenCL(TM) compute stacks supporting the GEN graphics hardware architecture.
Please refer to http://01.org/compute-runtime for additional details regarding Intel's motivation and intentions wrt OpenCL support in the open source.
