EPR #410797 - Specific OCL kernel is 5x slower on Hawaii than on Nvidia K40 GPU when tested under Linux.
- The logic for local workgroup size search was prioritizing ALU utilization, but with multidemensional launches X dimension could affect address calculation and cacheline utlization more than others. Add cacheline size into the consideration.

EPR #403782 - IOMMU2/SVM
- For finegrainsystem, the app can pass a malloced pointer directly to the kernel. Copy pointer directly to the aqlArgBuf without exiting.

ECR #333755 - Part 2- Update to foundation spec 1.0 20141019:
- hsa_dispatch_packet_t now becomes hsa_kernel_dispatch_packet_t
- all bit mask in a struct are removed and replaced by enums that indicates the bit position and width.
Test: TC precheckin

ECR #333753 - HSA RT/Compiler Lib/Performance: Elimination of HSAIL text usage in RT
Extracting HSAIL from the binary and parsing it for the kernel names in RT were replaced with aclQueryInfo call for RT_KERNEL_NAMES.
Kernel names are obtained now from the corresponding metadata symbols names, which are already presented in BIF at kernel finalization stage.
Side effect: performance improvement
Next Step: Performance: elimination of BRIG disassembling to HSAIL as obligatory stage in Compiler Lib (previously was needed only by RT).
Testing: pre check-in, ocl conformnace 2.0 (basic, api, compiler, workgroups, device_execution)

ECR #333753 - Compiler Lib/RT: Metadata related code refactor, annotation, minor fixes & additional checks
+ refactor if_aclQueryInfo() in order to simplify code and to avoid direct usage of aclMetadata struct members types
+ annotation on why we need to use deserializeCLMetadata on "serialized" (to NULL) pointers
+ erroneously forgotten RT_KERNEL_NAME was added to aclQueryType enum
+ OCLRTGetInfo, CLEnumCheck tests from ocltst oclcomplib was updated to use RT_KERNEL_NAME
+ testing of printf is added to OCLRTGetInfo
+ minor fixes and additional checks
tests: pre check-in, ocltst -m oclcomplib

ECR #333753 - HSA RT: avoiding superfluous recompilations on ORCA RT/HSA path
Next compilation stage determination based on binary sections and options (while linkImpl).
If current HSAILProgram options are equal to binarys ones:
- Do not generate BRIG if BRIG sections are already presented in binary.
- Do not finalize BRIG->ISA if ISA is already presented in binary.
- Perform only CG phase if HSAIL is absent in binary.
Always perform only brig loading (even in case of ISA presented).
Testing: pre check-in, compile & basic ocl conformance 2.0 tests

ECR #333753 - Compiler Lib & RT: Fix for Compiler's build log printing on RT.
+ RT now asks correctly Compiler's build log by aclGetCompilerLog().
+ BuildLog is added for HSAILKernel by moving it from NullKernel class to Kernel class.
+ Compiler's Lib appendLogToCL() is fixed.
+ Usage of API's aclExtractSection/aclExtractSymbol/aclInsertSection/aclInsertSymbol in Compiler Lib itself replaced by it's inner realizations extSec/extSym/insSec/insSym due to unneded build log clearing in first case.
+ Phase info is added to build log even if CallBack function is not presented for aclCompiler.
How to verify:
set AMD_OCL_BUILD_OPTIONS_APPEND="-print-compile-phases -buildlog=stdout"
test_integer_ops integer_ctz
test_integer_ops integer_ctz cpu
Testing: make smoke_clang, selective OCL conf. tests, pre check-in
