From: Suganath Prabu S <suganath-prabu.subramani@broadcom.com> * Set the coherent dma mask to 64 bit and then allocate RDPQ pools, make sure that each of the RDPQ pools satisfies the 4gb boundary restriction. if any of the RDPQ pool doesn't satisfies this restriction then deallocate the pools and reallocate them after changing the coherent dma mask to 32 bit. * With this there is no need to change DMA coherent mask when there are outstanding allocations in mpt3sas. * Code-Refactoring Suganath Prabu S (5): mpt3sas: Don't change the dma coherent mask after allocations mpt3sas: Rename function name is_MSB_are_same mpt3sas: Separate out RDPQ allocation to new function. mpt3sas: Handle RDPQ DMA allocation in same 4G region mpt3sas: Update mpt3sas version to 33.101.00.00 drivers/scsi/mpt3sas/mpt3sas_base.c | 279 +++++++++++++++++++++--------------- drivers/scsi/mpt3sas/mpt3sas_base.h | 9 +- 2 files changed, 171 insertions(+), 117 deletions(-)
